Even though building glibc with 64 bit time_t flags is not supported,
and the usual way is to patch the build system to avoid it; some
systems do enable it by default, and it increases the requirements
to build glibc in such cases (it also does not help newcomers when
trying to build glibc).
The conform namespace and linknamespace tests also do not expect
that flag to be set by default, so disable it as well.
Checked with a build/check for major ABI and some (i386, arm,
mipsel, hppa) with a toolchain that has LFS flags by default.

All the crypt related functions, cryptographic algorithms, and
make requirements are removed, with only the exception of md5
implementation which is moved to locale folder since it is
required by localedef for integrity protection (libc's
locale-reading code does not check these, but localedef does
generate them).
Besides thec code itself, both internal documentation and the
manual is also adjusted. This allows to remove both --enable-crypt
and --enable-nss-crypt configure options.
Checked with a build for all affected ABIs.

I used these shell commands:
../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright
(cd ../glibc && git commit -am"[this commit message]")
and then ignored the output, which consisted lines saying "FOO: warning:
copyright statement not found" for each of 7061 files FOO.
I then removed trailing white space from math/tgmath.h,
support/tst-support-open-dev-null-range.c, and
sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following
obscure pre-commit check failure diagnostics from Savannah. I don't
know why I run into these diagnostics whereas others evidently do not.

My glibc bot showed that my conformtest changes fail the build of the
conformtest execution tests for x86_64-linux-gnu-static-pie, because
linking the newly built object with the newly built libc and the
associated options normally used for linking requires it to be built
as PIE. Add $(pie-default) to the compiler command used so that PIE
options are used when required.
There's a case for using the whole of $(CFLAGS-.o) (which includes
$(pie-default)), but that raises questions of any impact from using
optimization flags from CFLAGS in these tests. So for now just use
$(pie-default) as the key part of $(CFLAGS-.o) that's definitely
needed.
Tested with build-many-glibcs.py for x86_64-linux-gnu-static-pie.

Although the conform/ header tests are built using the headers of the
glibc under test, the execution tests from conformtest (a few tests of
the values of macros evaluating to string constants) are linked and
run with system libc, not the newly built libc.
Apart from preventing testing in cross environments, this can be a
problem even for native testing. Specifically, it can be useful to do
native testing when building with a cross compiler that links with a
libc that is not the system libc; for example, on x86_64, you can test
all three ABIs that way if the kernel support is present, even if the
host OS lacks 32-bit or x32 libraries or they are older than the
libraries in the sysroot used by the compiler used to build glibc.
This works for almost all tests, but not for these conformtest tests.
Arrange for conformtest to link and run test programs similarly to
other tests, with consequent refactoring of various variables in
Makeconfig to allow passing relevant parts of the link-time command
lines down to conformtest. In general, the parts of the link command
involving $@ or $^ are separated out from the parts that should be
passed to conformtest (the variables passed to conformtest still
involve various variables whose names involve $(@F), but those
variables simply won't be defined for the conformtest makefile rules
and I think their presence there is harmless).
This is also most of the support that would be needed to allow running
those tests of string constants for cross testing when test-wrapper is
defined. That will also need changes to where conformtest.py puts the
test executables, so it puts them in the main object directory
(expected to be shared with a test system in cross testing) rather
than /tmp (not expected to be shared) as at present.
Tested for x86_64.

The stub implementations are turned into compat symbols.
Linux actually has two reserved system call numbers (for getpmsg
and putpmsg), but these system calls have never been implemented,
and there are no plans to implement them, so this patch replaces
the wrappers with the generic stubs.
According to <https://bugzilla.redhat.com/show_bug.cgi?id=436349>,
the presence of the XSI STREAMS declarations is a minor portability
hazard because they are not actually implemented.
This commit does not change the TIRPC support code in
sunrpc/rpc_svcout.c. It uses additional XTI functionality and
therefore never worked with glibc.

Continuing the consolidation on Python for various miscellaneous build
and test scripts, this patch moves conformtest from Perl to Python.
The substance of the tests run is intended to be the same as before,
except that the previous test for tags did not actually achieve the
intended purpose of verifying whether a tag was already declared, so
is changed to one that would actually fail for a tag that wasn't
declared, and a typo in the old test for variables being available
($xyzzy instead of xyzzy) would have made that test not use the
correct type (but it would have passed anyway with warnings). No
attempt is made to keep the details of what the test output looks
like; instead, tests are given names which are made to follow PASS: /
FAIL: / XFAIL: / SKIP: / MISSING: as appropriate.
In the new version, there is more consistent parsing of test lines
(into a series of words, either surrounded by {} or separated by
spaces) that applies for all kinds of test lines, rather than the old
approach of different regular expressions for every kind of test. A
few of the conform/data/ files are adjusted so their syntax works with
the new script (which now requires spaces in certain cases where the
old script tolerated them being missing, and does not allow stray
semicolons at the end of "function" lines). Similarly, common logic
is used around what happens with a second subtest if a first one fails
(e.g., a test for a symbol's type if the test for availability fails),
rather than such logic being replicated separately for each kind of
test. Common parsing also applies for test lines both when they are
lines for the header under test and when they are lines for another
header specified with allow-header, again unlike the old script.
Tested for x86_64, and with build-many-glibcs.py.

This patch replaces conform/linknamespace.pl with a new
conform/linknamespace.py, so continuing the consolidation on Python
instead of Perl for miscellaneous scripts used in building and testing
glibc. The new script follows the same logic as the old one; as a
recently-added script, there were no major cleanups to be made in the
course of the language conversion.
Tested for x86_64, and with build-many-glibcs.py. For x86_64 I also
tested that if the Perl and Python scripts were made to print all the
symbols in seen_where and the paths of symbol references by which
those symbols were linked in, even when those symbols were OK,
identical symbol lists appeared in the output with both versions of
the script (the differences in linknamespace.out files were only in
paths to temporary files in diagnostics for e.g. deprecated functions,
and error output for the expected compilation failures when testing
ndbm.h and varargs.h).

This patch makes Python 3.4 or later a required tool for building
glibc, so allowing changes of awk, perl etc. code used in the build
and test to Python code without any such changes needing makefile
conditionals or to handle older Python versions.
This patch makes the configure test for Python check the version and
give an error if Python is missing or too old, and removes makefile
conditionals that are no longer needed. It does not itself convert
any code from another language to Python, and does not remove any
compatibility with older Python versions from existing scripts.

This patch adds the thrd_* definitions from C11 threads (ISO/IEC 9899:2011),
more specifically thrd_create, thrd_curent, rhd_detach, thrd_equal,
thrd_exit, thrd_join, thrd_sleep, thrd_yield, and required types.
Mostly of the definitions are composed based on POSIX conterparts, such as
thrd_t (using pthread_t). For thrd_* function internally direct
POSIX pthread call are used with the exceptions:
1. thrd_start uses pthread_create internal implementation, but changes
how to actually calls the start routine. This is due the difference
in signature between POSIX and C11, where former return a 'void *'
and latter 'int'.
To avoid calling convention issues due 'void *' to int cast, routines
from C11 threads are started slight different than default pthread one.
Explicit cast to expected return are used internally on pthread_create
and the result is stored back to void also with an explicit cast.
2. thrd_sleep uses nanosleep internal direct syscall to avoid clobbering
errno and to handle expected standard return codes. It is a
cancellation entrypoint to be consistent with both thrd_join and
cnd_{timed}wait.
3. thrd_yield also uses internal direct syscall to avoid errno clobbering.
Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu,
arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu, m68k-linux-gnu,

This patch completes the ucontext.h namespace fixes by fixing issues
related to the use of struct sigcontext as mcontext_t, and inclusion
of <bits/sigcontext.h> even when struct sigcontext is not so used.
Inclusion of <bits/sigcontext.h> by <sys/ucontext.h> is removed; the
way to get the sigcontext structure is by including <signal.h> (in a
context where __USE_MISC is defined); the sysdeps/generic version of
sys/ucontext.h keeps the inclusion by necessity, with a comment about
how this is not namespace-clean, but the only configuration that used
it, MicroBlaze, gets its own version of the header in this patch.
Where mcontext_t was typedefed to struct sigcontext, the contents of
struct sigcontext are inserted (with appropriate namespace handling to
prefix fields with __ when __USE_MISC is not defined); review should
check that this has been done correctly in each case, whether the
definition of struct sigcontext comes from glibc headers or from the
Linux kernel. This changes C++ name mangling on affected
architectures (which do not include x86_64/x86).
Tested for x86_64, and with build-many-glibcs.py.

In sys/wait.h, waitid and associated constants and types are UX-shaded
in XPG4.2 (so not in XPG4), and XSI-shaded in POSIX before 2008, so
should be appropriately conditional in the headers. This patch fixes
the conditionals accordingly. (WCONTINUED is actually still
XSI-shaded in POSIX.1:2008, but W* is also reserved there without
XSI-shading, so nothing special needs to be done about the
conditionals on WCONTINUED to conform to POSIX.1:2008 namespace
rules.)

This patch corrects the conformtest expectations for sys/wait.h for
XPG4. This does not change the test results for this header at the
makefile level since it fixes some spurious failures for this header
while introducing other failures previously hidden by incorrect
expectations. However, it shows up issues with stdlib.h for XPG4
defining W* names that are not permitted in this case (previously

conform/ namespace tests of arpa/inet.h, netdb.h and netinet/in.h fail
for UNIX98 and XPG42 because of inclusion of stdint.h, which defines
macros not permitted in those headers for those standards. UNIX98
allows them to include inttypes.h, but (predating C99) has restricted
inttypes.h contents (not yet tested in the conform/ tests) not
including those macros; XPG4.2 has no such permission and no
inttypes.h / stdint.h at all.
This patch rearranges the headers to avoid this issue. intN_t
definitions move to bits/stdint-intn.h, and uintN_t definitions to
bits/stdint-uintn.h. (These are not bits/types/ headers because they
each define four types. They are separate rather than just a single
header because sys/types.h defines intN_t but u_intN_t rather than
uintN_t - and while sys/types.h could define uintN_t because of the
POSIX reservation of *_t, existing practice there is largely to
condition types on appropriate feature test macros, and indeed there
is at least one open bug report (14553) about a type that's not
so-conditioned, so maybe types there should actually have conditions
added where appropriate.) The affected network headers are then made
to include bits/stdint-uintn.h instead of stdint.h. This allows six
XFAILs to be removed.
This doesn't do anything about inttypes.h defining more than it should
for UNIX98, but we don't have conformtest expectations for that case
at present (and my inclination is that a fix for that should be as
local as possible - affecting only inttypes.h, not stdint.h, only for
the case of __USE_UNIX98 && !__USE_ISOC99).
Tested for x86_64.
