Subject: iconv: Add UTF-7-IMAP variant in utf-7.c

UTF-7-IMAP differs from UTF-7 in the followings ways (see RFC 3501[1]
for reference) :

- The shift character is '&' instead of '+'
- There is no "optional direct characters" and the "direct characters"
  set is different
- There is no implicit shift back to US-ASCII from BASE64, all BASE64
  sequences MUST be terminated with '-'
