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.

adds support for named subpatterns to `mb_ereg_replace`

Named subpatterns are now passed to `mb_ereg_replace_callback`.

This commit also adds a subset of the oniguruma back-reference syntax
for replacements:
* `\k<name>` and `\k'name'` for named subpatterns.
* `\k<n>` and `\k'n'` for numbered subpatterns
These last two notations allow referencing numbered groups where n > 9.

Fix #76113: mbstring does not build with Oniguruma 6.8.1

As of Oniguruma 6.8.1, the regex structure has been moved from the
public `oniguruma.h` to the private `regint.h`. Thus, it is no longer
possible to directly access the struct's members, and actually, there
is no need to, since there are respective accessor functions available
at least of 2.3.1.
