* zend_globals: Embed `in_autoload` into `zend_executor_globals`
Nowadays virtually any PHP application is making use of autoloading, making the
lazy allocation of the `HashTable` struct a needless pointer indirection.
* zend_globals: Rename `in_autoload` to `autoload_current_classnames`
The old name `in_autoload` was somewhat misleading by implying a `bool`ean
value rather than a `HashTable`. Since the previous change to embed the
`HashTable` is breaking anyway, we can also rename it.

As of PHP 8.5 the minimum required SQLite library is 3.7.17, and this
removes the following preprocessor macros checks:
- HAVE_SQLITE3_CLOSE_V2 (sqlite3_close_v2() function is available since
SQLite 3.7.14.)
- HAVE_SQLITE3_ERRSTR (sqlite3_errstr() function is available since
SQLite 3.7.15)
- SQLITE_VERSION_NUMBER should be now always greater than 3006011
(3.6.11).
The AC_STRUCT_ST_BLOCKS expects fileblocks object to be compiled with
AC_LIBOBJ if stat.st_blocks is missing on the system. This can be
simplified with the usual AC_CHECK_MEMBERS since PHP is using the
stat.st_blocks (and stat.st_blksize) conditionally.
These members are mostly present on all POSIX-based systems except on
Windows these days.
This also removes the obsolete HAVE_ST_BLOCKS symbol:
https://git.savannah.gnu.org/cgit/autoconf.git/tree/lib/autoconf/types.m4?h=v2.72#n1055
Additionally, the st_blksize and st_blocks members are checked
conditionally with HAVE_ preprocessor macros. Instead of filtering
Windows specifically here, the preprocessor macros
HAVE_STRUCT_STAT_ST_BLKSIZE and HAVE_STRUCT_STAT_ST_BLOCKS can be used.
At the time of writing, PHP found on host system must be at least 8.0
for build/gen_stub.php and Zend/zend_vm_gen.php scripts to work.
Minimum required version is updated to 8.1 to still support building PHP
from source on any possible old systems, and enabling new features in
build/gen_stub.php, such as readonly properties.
Rather than "manually" doing it in the READ handler.
At the same time, get rid of various inconsistent legacy handler macro definitions, thus mandating all modules to implement the create and validate SID handlers.
The only handler that remains optional is the update timestamp one.
in the ipv6 address creation helper we need to use, for the error
message, the converted data rather than assuming the original
is a proper zend_string().

The SysV shared memory allocator in OPcache hardcodes a maximum segment size of
32MB (SEG_ALLOC_SIZE_MAX). If the JIT buffer exceeds this, which it does with
the default 64MB size, startup will fail with "Insufficient shared memory!".
The allocator will now try allocating a contiguous buffer first, and only then
use segmentation by searching for continuously smaller powers of 2.
