Be more precise about possible types for mysqli methods

mysqli has an uncommon approach to 64-bit compatibility:
it will convert numbers that can't be represented on 32-bit
platforms

Be more precise about possible types for mysqli methods

mysqli has an uncommon approach to 64-bit compatibility:
it will convert numbers that can't be represented on 32-bit
platforms to a string.
This is documented at
https://www.php.net/manual/en/mysqli-stmt.affected-rows.php#refsect1-mysqli-stmt.affected-rows-returnvalues

So if there's a query to a remote mysqli server that affects
more than 2.2 billion rows, then the opcache inference might be
incorrect.

(It's possible to add a MAY_BE_STRING_ON_32_BIT_PLATFORM bitflag macro to
account for this, but I don't think there's a need or want to?)

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.

This is a very very old thing dated back to year 2009.
MYSQL_OPT_READ_TIMEOUT was never a macro in mysqlnd but an enum value.
So this never actually worked correctly. mysqlnd provides these so it is
safe to have them when mysqlnd used.
