* Remove unused upper case tag static data
* Shrink size of static binary search tree
This also makes it more efficient on the data cache.
* Update patches
* Avoid passing NULL to xmlSwitchToEncoding
This otherwise switches to UTF-8 on libxml2 2.12.0
* Split tests for different error reporting behaviour in libxml2 2.12.0
* Avoid deprecation warnings for libxml2 2.12.0
We can't fully get rid of the parser globals as there are still APIs
that implicitly use them.
* Temporarily disable part of test for libxml 2.12.0 regression
See https://gitlab.gnome.org/GNOME/libxml2/-/issues/634
* Review fixes
* [ci skip] Update test description
The former implementation of huge pages for PHP code segments may
fail to map in certain scenarios. For instance, if the initial
'r-x-' segment is not PHP, it will result in a failure to map into
huge pages. Consequently, the optimization for huge pages with PHP
code will no longer be effective.
This patch improves the implementation by accurately matching all
'r-x-' segments until it locates the PHP code segment. Subsequently,
it performs the necessary huge page mapping.

This is _not_ exploitable right now because libxml guarantees right now
a maximum string length of 1M bytes. But if that limit were to ever
change this could overflow in the future leading to exploits.
Again, not exploitable right now, but just making it more future-proof.
* Fast path for when there is nothing to trim in mb_trim
* Make mb_trim decide between linear search vs hash table lookup
Using empirical experiments I noticed that on my i7-4790 the hash table
approach becomes faster once we have more than 4 code points in the trim
characters, when evaluated on the worst case.
This patch changes the logic so that a hash table is used for a large
number of trim characters, and linear search when the number of trim
characters is <= 4.
Some jobs on GA apparently consume a lot of CPU resources, possibly hindering
communication between master and runner. This only seems to happen on Linux+ASAN
and macOS. For these jobs, keep one core idle.
Closes GH-12742
Now that we have class aliases (DOMNode -> DOM\Node), it has become important to add them to the class map so that it will be possible to generate class synopses for them.
This has been the case at least since PHP 5.4. Thanks to Girgias for
pointing it out.
It appears that there are several global variables internal to mbstring
which can be queried via mb_get_info() and which could be NULL, but
at the very least, we know that "mbstring.http_input" is one of them.
