This also fixes the build for AArch64 since cmph_uint32 is not big
enough to hold a pointer there. I found this while building for CHERI
since the compiler errors there when casting from a non-inptr_t integer.
This also fixes warnings when building for AArch64 with clang.
This doesn't appear to work reliably on s390x and ppc64, returning
the results that were expected without %E or intermittently crashing.
It seems that on little-endian 64-bit, the intptr_t returned by the
undocumented _NL_TIME_ERA_NUM_ENTRIES correctly has the number of entries
in its low-order half (at the time of writing, 0x0000'0000'0000'000b for
Japan), but on big-endian 64-bit, it has the number of entries in its
high-order half instead (for example 0x0000'000b'0000'0000 for Japan),
with the low-order half being all-zero or possibly uninitialized.
Making this reliable will require some sort of defined API from glibc.

We only care about the introspection data for documentation purposes;
the GStaticMutex and GStaticRecMutex types are long since deprecated,
and they cannot be used from language bindings anyway, so their size is
immaterial.

There are several reasons why we might not be able to do the test setup
for --external-data: non-Linux platform, missing ld or objcopy,
objcopy doesn't support --add-symbol, or the CPU family is MIPS
(on which cc -r does not necessarily emit the specific MIPS ABI flavour
that we are targeting, for example different functionality levels or
different NaN encodings).
If we can't link in the test data, then obviously this test is not going
to pass. It was already skipped on non-Linux, but not on platforms that
hit one of the other reasons for the test setup to fail.
In particular, this test failed on Debian mips64el since commit 81059169,
which stopped linking the necessary resource on MIPS platforms, but
continued to assert that the resource is present at runtime.

Now that the reference documentation uses gi-docgen, it's more
troublesome to generate in less standard build scenarios like
cross-compiling.
In distributions like Debian, reference documentation is generally
packaged separately (in libglib2.0-doc in Debian's case), but man pages
are generally packaged alongside the executables themselves (in the
libglib2.0-bin and libglib2.0-dev-bin packages, in Debian's case). We
can exclude the reference documentation when cross-compiling, but ideally
we would like the man pages to still be built, so that a cross-compiled
libglib2.0-bin or libglib2.0-dev-bin package has the same content as a
native build.

Previously, the girs and typelibs generated from gobject-introspection
ommited the deprecated apis, however we want them annotated for
documentation purposes.
Skip the deprecated gthead api so they do not make it into the
typelibs which caused problems as not all the symbols exist.

Comparing reallocated pointers is UB, but this happens to work for now
on most compilers. However, for CHERI systems if g_bsearch_array_insert()
reallocs in-place then the new `hlbsa` pointer may have larger bounds
than `o` and using the old pointer with the smaller bounds can result
in a bounds error. I don't think this code is performance critical, so
removing the optimization and inserting unconditionally should be fine.
Currently, this realloc() UB rarely causes issues, but newer versions of
GCC with _FORTIFY_SOURCE=3 might also be able to observe the valid
memory range (assuming sufficient inlining).

Not sure what it was doing there — these arguments get written to as
part of the invocation. The in-args should be `const` qualified, but not

The whole point of a `GICallableInfo` struct is to contain information
about how a function is callable, and that includes information about
whether it’s a method and whether it throws a `GError`. The caller
shouldn’t need to specify those things separately.
So drop those arguments.

It was deprecated since before libgirepository was moved into this
repository. Take the opportunity now to remove it entirely, as it’s a
bit confusing to have it in the public API.
This should not affect the binary typelib format, as it still has its
`BLOB_TYPE_INVALID_0` member, and that will remain in place until the
binary format next breaks compatibility (no plans to do that).

And rename it to `gi_repository_get_shared_libraries()`. Previously it
returned a comma-separated string, which wasn’t particularly typesafe or
machine-friendly. Now it returns the same data as an array.

Having it be nullable means the type system forces the caller to check
the result for nullability every time, even though it’s straightforward
for the caller to check the index argument in advance and guarantee a
non-`NULL` result.
Change `gi_repository_get_info()` to never return `NULL` to tidy this
up. This also brings it inline with other `gi_*_get_info()` functions,
which are not nullable.

In general, we must not call out to external, unknown code while holding
a lock. That is prone to dead lock.
g_object_ref() can emit a toggle notification. In g_weak_ref_set(), we
must not do that while holding the lock.
