Check for VM limit RPCs
* config.h.in: add #undef for HAVE_MACH_VM_GET_SIZE_LIMIT and
HAVE_MACH_VM_SET_SIZE_LIMIT.
* sysdeps/mach/configure.ac: use mach_RPC_CHECK to check for
vm_set_size_limit and vm_get_size_limit RPCs in gnumach.defs.
* sysdeps/mach/configure: regenerate file.
Use vm_get_size_limit to initialize RLIMIT_AS
* hurd/hurdrlimit.c(init_rlimit): use vm_get_size_limit to initialize
RLIMIT_AS entry of the _hurd_rlimits array.
Notify the kernel of the new VM size limits
* sysdeps/mach/hurd/setrlimit.c: use the vm_set_size_limit RPC,
if available, to notify the kernel of the new limits. Retry RPC
calls if they were interrupted by a signal.

Check the availability of host_get_time64 and use it to replace
host_get_time for CLOCK_REALTIME when it's available. Fall back to
host_get_time if gnumach does not support host_get_time64 but the
gnumach headers do.
host_get_time is deprecated
See https://git.savannah.gnu.org/cgit/hurd/gnumach.git/commit/?id=569df850cd7badd1e36132ad3b44aa76a4d27c25
However, it's kept for backward compactbility.
* config.h.in: Add HAVE_HOST_GET_TIME64 config entry.
* sysdeps/mach/clock_gettime.c: Use host_get_time64 for CLOCK_REALTIME
when it's possible, fall to host_get_time otherwise.
* sysdeps/mach/configure: Check the existence of host_get_time64 RPC.
* sysdeps/mach/configure.ac: Check the existence of host_get_time64 RPC.

The Mach RPC host_get_uptime64() is implemented. It returns the elapsed time
value since bootup. See
https://git.savannah.gnu.org/cgit/hurd/gnumach.git/commit/?id=fc494bfe3fb6363e1077dc035eb119970d84a9d1
In this patch, the RPC is used to implement the monotonic clock for
mach.
* config.h.in: Add HAVE_HOST_GET_UPTIME64 config entry
* sysdeps/mach/clock_gettime.c: Add CLOCK_MONOTONIC case
* sysdeps/mach/configure: Check the existence of host_get_uptime64 RPC
* sysdeps/mach/configure.ac: Check the existence of host_get_uptime64 RPC

We use thread_get_name and thread_set_name to get and set the thread
name, so nothing is stored in the thread structure since these functions
are supposed to be called sparingly.
One notable difference with Linux is that the thread name is up to 32
chars, whereas Linux's is 16.
Also added a mach_RPC_CHECK to check for the existing of gnumach RPCs.

Bump autoconf requirement to 2.71 to allow regenerating configure on
more recent distributions. autoconf 2.71 has been in Fedora since F36
and is the current version in Debian stable (bookworm). It appears to
be current in Gentoo as well.
All sysdeps configure and preconfigure scripts have also been
regenerated; all changes are trivial transformations that do not affect
functionality.

We do not want mach_i386.h to get installed into machine/, but into
i386/ or x86_64/ depending where mach_i386.defs was found, i.e.
according to 32/64 bitness.
We already did the same change for Hurd
(https://git.savannah.gnu.org/cgit/hurd/hurd.git/commit/?id=ef5924402864ef049f40a39e73967628583bc1a4)
Due to MiG requiring the subsystem to be defined early in order to know the
size of a port, this was causing a division by zero error during ./configure.
We could have just move subsystem to the top of the snippet, however it is
simpler to just remove the check given that we have no plans to use some other
MiG anyway.
HAVE_MIG_RETCODE is removed completely since this will be a no-op either
way (compiling against old Hurd headers will work the same, new Hurd
headers will result in the same stubs since retcode is a no-op).

8b8c768e3c ("Force use of -ffreestanding when checking for gnumach
headers") was passing -ffreestanding to CFLAGS only, but headers checks are
performed with the preprocessor, so we rather need to pass it to CPPFLAGS.
Without this ./configure assumes that we are in a fully hosted
environment, which might not be the case. After this patch, we can rely on
the freestanding header files provided by GCC such as stdint.h.

This patch replaced obsolete AC_TRY_COMPILE to AC_COMPILE_IFELSE or
AC_PREPROC_IFELSE.
It has been confirmed that GNU 'autoconf' 2.69 suppressed obsolete
warnings, updated the following files:
- configure
- sysdeps/mach/configure
- sysdeps/mach/hurd/configure
- sysdeps/s390/configure
- sysdeps/unix/sysv/linux/configure
and didn't change the following files:
