Disallow pending interrupts to be checked during `FiberScheduler#unblock`.
Ractors can send signals at any time, so the previous debug assertion can fail if a Ractor sends a signal.

Prism can parse multiple versions of ruby. Because of that branch release managers are ok with simply
bumping prism to its latest version.
However, if no version is specified, it will parse as the latest known version, which can be ahead of the maintenance branch.
So we need to explicitly pass a version to not accidentally introduce new syntax to maintenance branches.

Cast up `int` instruction code to `VALUE`
Fix Visual C warnings:

iseq.c(3793): warning C4312: 'type cast': conversion from 'int' to 'void *' of greater size

Do not let files depend on a phony target
Detect `clock_gettime` and `clock_getres` for winpthreads
Fix Symbol#to_proc (rb_sym_to_proc) to be ractor safe
In non-main ractors, don't use `sym_proc_cache`. It is not thread-safe
to add to this array without a lock and also it leaks procs from one
ractor to another. Instead, we create a new proc each time. If this
results in poor performance we can come up with a solution later.
Fixes [Bug #21354]
Fix redefinition of `clock_gettime` and `clock_getres`
winpthreads-git 12.0.0.r720 provides `clock_gettime` and
`clock_getres` as inline functions.
digest.so needs ruby/digest.h which is installed by build-ext
Copy to path with the base name
[Bug #21170]
st_table reserves -1 as a special hash value to indicate that an entry
has been deleted. So that that's a valid value to be returned from the
hash function, do_hash replaces -1 with 0 so that it is not mistaken for
the sentinel.
Previously, when upgrading an AR table to an ST table,
rb_st_add_direct_with_hash was used which did not perform the same
conversion, this could lead to a hash in a broken state where one if its
entries which was supposed to exist being marked as a tombstone.
The hash could then become further corrupted when the ST table required
resizing as the falsely tombstoned entry would be skipped but it would
be counted in num entries, leading to an uninitialized entry at index
15.
In most cases this will be really rare, unless using a very poorly
implemented custom hash function.
This also adds two debug assertions, one that st_add_direct_with_hash
does not receive the reserved hash value, and a second in
rebuild_table_with, which ensures that after we rebuild/compact a table
it contains the expected number of elements.

We have name fragmentation for this feature, including "shared GC",
"modular GC", and "external GC". This commit standardizes the feature
name to "modular GC" and the implementation to "GC library".
Use PR_SET_VMA_ANON_NAME to set human-readable names for anonymous
virtual memory areas mapped by `mmap()` when compiled and run on Linux
5.17 or higher. This makes it convenient for developers to debug mmap.
This will add +MOD_GC to the version string and Ruby description when
Ruby is compiled with shared gc support.
When shared GC support is compiled in and a GC module has been loaded
using RUBY_GC_LIBRARY, the version string will include the name of
the currently active GC as reported by the rb_gc_active_gc_name function
in the form
+MOD_GC[gc_name]
