elf: Add missing dependency between resolvfail and testobj1.so
It was possible to run this test individually and have it fail because
it can't find testobj1.so.  This patch adds that dependency, to prevent
such issues.

libio: Do not autogenerate stdio_lim.h
Instead define the required fields in system dependend files.  The only
system dependent definition is FILENAME_MAX, which should match POSIX
PATH_MAX, and it is obtained from either kernel UAPI or mach headers.
Currently set pre-defined value from current kernels.

It avoids a circular dependendy when including stdio.h in
gen-as-const-headers files.

stdio-common: tests: don't double-define _FORTIFY_SOURCE
Exactly the same as 35bcb08eaa953c9b8bef6ab2486dc4361e1f26c0.

If using -D_FORITFY_SOURCE=3 (in my case, I've patched GCC to add
=3 instead of =2 (we've done =2 for years in Gentoo)), building
glibc tests will fail on tst-bz11319-fortify2 like:
```
<command-line>: error: "_FORTIFY_SOURCE" redefined [-Werror]
<built-in>: note: this is the location of the previous definition
cc1: all warnings being treated as errors
```

It's just because we're always setting -D_FORTIFY_SOURCE=2
rather than unsetting it first. If F_S is already 2, it's harmless,
but if it's another value (say, 1, or 3), the compiler will bawk.

(I'm not aware of a reason this couldn't be tested with =3,
but the toolchain support is limited for that (too new), and we want
to run the tests everywhere possible.)

As Siddhesh noted previously, we could implement some fallback
logic to determine the maximal F_S value supported by the toolchain,
which is a bit easier now that autoconf-archive has been updated for F_S=3
(https://github.com/autoconf-archive/autoconf-archive/pull/269), but let's
revisit this if it continues to crop up.

linux: fix ntp_gettime abi break (BZ# 30156)
Between versions v2.11 and v2.12 struct ntptimeval got new fields.
That wasn't a problem because new function ntp_gettimex was created
(and made default) to support new struct.  Old ntp_gettime was not
using new fields so it was safe to call with old struct
definition.  Then commits 5613afe9e3dff and b6ad64b907a (added for
64 bit time_t support), ntp_gettime start setting new fields.

Sets fields manually to maintain compatibility with v2.11 struct
definition.

Resolves #30156

hppa: Drop 16-byte pthread lock alignment
Linux threads were removed about 12 years ago and the current
nptl implementation only requires 4-byte alignment for pthread
locks.

The 16-byte alignment causes various issues. For example in
building ignition-msgs, we have:

/usr/include/google/protobuf/map.h:124:37: error: static assertion failed
  124 |  static_assert(alignof(value_type) <= 8, "");
      |                ~~~~~~~~~~~~~~~~~~~~^~~~

This is caused by the 16-byte pthread lock alignment.

LoongArch: ldconfig: Ignore EF_LARCH_OBJABI_V1 in shared objects
Binutils 2.40 sets EF_LARCH_OBJABI_V1 for shared objects:

    $ ld --version | head -n1
    GNU ld (GNU Binutils) 2.40
    $ echo 'int dummy;' > dummy.c
    $ cc dummy.c -shared
    $ readelf -h a.out | grep Flags
    Flags:                            0x43, DOUBLE-FLOAT, OBJ-v1

We need to ignore it in ldconfig or ldconfig will consider all shared
objects linked by Binutils 2.40 "unsupported".  Maybe we should stop
setting EF_LARCH_OBJABI_V1 for shared objects, but Binutils 2.40 is
already released and we cannot change it.

Move libc_freeres_ptrs and libc_subfreeres to hidden/weak functions
They are both used by __libc_freeres to free all library malloc
allocated resources to help tooling like mtrace or valgrind with
memory leak tracking.

The current scheme uses assembly markers and linker script entries
to consolidate the free routine function pointers in the RELRO segment
and to be freed buffers in BSS.

This patch changes it to use specific free functions for
libc_freeres_ptrs buffers and call the function pointer array directly
with call_function_static_weak.

It allows the removal of both the internal macros and the linker
script sections.

Remove set-hooks.h from generic includes
The hooks mechanism uses symbol sets for running lists of functions,
which requires either extra linker directives to provide any hardening
(such as RELRO) or additional code (such as pointer obfuscation via
mangling with random value).

Currently only hurd uses set-hooks.h so we remove it from the generic
includes.  The generic implementation uses direct function calls which
provide hardening and good code generation, observability and debugging
without the need for extra linking options or special code handling.

Update printf %b/%B C2x support
WG14 recently accepted two additions to the printf/scanf %b/%B
support: there are now PRIb* and SCNb* macros in <inttypes.h>, and
printf %B is now an optional feature defined in normative text,
instead of recommended practice, with corresponding PRIB* macros that
can also be used to test whether that optional feature is supported.
See N3072 items 14 and 15 for details (those changes were accepted,
some other changes in that paper weren't).

Add the corresponding PRI* macros to glibc and update one place in the
manual referring to %B as recommended.  (SCNb* should naturally be
added at the same time as the corresponding scanf %b support.)

Tested for x86_64 and x86.

memalign: Support scanning for aligned chunks.
This patch adds a chunk scanning algorithm to the _int_memalign code
path that reduces heap fragmentation by reusing already aligned chunks
instead of always looking for chunks of larger sizes and splitting
them.  The tcache macros are extended to allow removing a chunk from
the middle of the list.

The goal is to fix the pathological use cases where heaps grow
continuously in workloads that are heavy users of memalign.

Note that tst-memalign-2 checks for tcache operation, which
malloc-check bypasses.
