Fix #63839: iconv_mime_decode_headers function is skipping headers

We have to cater to the possibility that `=?` is not the start of an
encoded-word, but rather a literal `=?`. If a line break is found
while we're still looking for the charset, we can safely assume that
it's a literal `=?`, and act accordingly.

Fix #53891: iconv_mime_encode() fails to Q-encode UTF-8 string

The minimum length of an encoded-word is actually the pure encoding
overhead plus the length of the `output-charset` plus the minimum unit
of encoded text, which is 4 for B-encoding and (for simplicity) 3 for
Q-encoding. We also cater to the possibility that we need further
encoded words, which would be split by the `line-break-chars` followed
by a space character. Obviously, the former `out_charset_len + 12` is
too simplistic and wrong in the given case (where the magic number
would be 13).

These simplifications are somewhat wasteful, but iconv_mime_encode()
with Q-encoding is wasteful anyway (see bug 66828[1]), and the proper
solution to convert the whole input to the desired output charset
upfront, and applying the encoding afterwards appears too much a change
for the stable releases.

Remove unused Git attributes ident

The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.

In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.

This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
