hurd: Fix pselect atomicity
In case the signal arrives before the __mach_msg call, we need to catch
between the sigprocmask call and the __mach_msg call.  Let's just reuse
the support for sigsuspend to make the signal send a message that
our __mach_msg call will just receive.

* hurd/hurdselect.c (_hurd_select): Add sigport and ss variables. When
sigmask is not NULL, create a sigport port and register as
ss->suspended.  Add it to the portset.  When we receive a message on it,
set error to EINTR.  Clean up sigport and portset appropriately.

* hurd/hurdsig.c (wake_sigsuspend): Note that pselect also uses it.

y2038: Replace __clock_gettime with __clock_gettime64
The __clock_gettime internal function is not supporting 64 bit time on
architectures with __WORDSIZE == 32 and __TIMESIZE != 64 (like e.g. ARM 32
bit).

The __clock_gettime64 function shall be used instead in the glibc itself as
it supports 64 bit time on those systems.
This patch does not bring any changes to systems with __WORDSIZE == 64 as
for them the __clock_gettime64 is aliased to __clock_gettime (in
./include/time.h).

elf: Turn _dl_printf, _dl_error_printf, _dl_fatal_printf into functions
This change makes it easier to set a breakpoint on these calls.

This also addresses the issue that including <ldsodefs.h> without
<unistd.h> does not result usable _dl_*printf macros because of the
use of the STD*_FILENO macros there.

(The private symbol for _dl_fatal_printf will go away again

elf: Do not read hwcaps from the vDSO in ld.so
This was only ever used for the "nosegneg" flag.  This approach for

y2038: linux: Provide __clock_adjtime64 implementation
This patch replaces auto generated wrapper (as described in
sysdeps/unix/sysv/linux/syscalls.list) for clock_adjtime with one which adds
extra support for reading 64 bit time values on machines with __TIMESIZE != 64.

To achieve this goal new __clock_adjtime64 explicit 64 bit function for
adjusting Linux clock has been added.
Moreover, a 32 bit version - __clock_adjtime has been refactored to internally
use __clock_adjtime64.

The __clock_adjtime is now supposed to be used on systems still supporting 32
bit time (__TIMESIZE != 64) - hence the necessary conversions between 64 bit
struct __timespec64 and struct timespec.

The new __clock_adjtime64 syscall available from Linux 5.1+ has been used, when
applicable.
Up till v5.4 in the Linux kernel there was a bug preventing this call from
obtaining correct struct's timex time.tv_sec time after time_t overflow
(i.e. not being Y2038 safe).

Build tests:
- ./src/scripts/build-many-glibcs.py glibcs

Run-time tests:
- Run specific tests on ARM/x86 32bit systems (qemu):
  https://github.com/lmajewski/meta-y2038 and run tests:
  https://github.com/lmajewski/y2038-tests/commits/master

Linux kernel, headers and minimal kernel version for glibc build test matrix:
- Linux v5.1 (with clock_adjtime64) and glibc build with v5.1 as
  minimal kernel version (--enable-kernel="5.1.0")
  The __ASSUME_TIME64_SYSCALLS flag defined.

- Linux v5.1 and default minimal kernel version
  The __ASSUME_TIME64_SYSCALLS not defined, but kernel supports clock_adjtime64
  syscall.

- Linux v4.19 (no clock_adjtime64 support) with default minimal kernel version
  for contemporary glibc (3.2.0)
  This kernel doesn't support clock_adjtime64 syscall, so the fallback to
  clock_adjtime is tested.

Above tests were performed with Y2038 redirection applied as well as without
(so the __TIMESIZE != 64 execution path is checked as well).

No regressions were observed.

Historically, this mechanism was used to process "nosegneg"

subdirectories.  With nosegneg support gone from ld.so, this is part

The entire mechanism is not well-designed because it causes the

that was used to generate the cache, which makes it difficult to use
this mechanism for anything else in the future.

y2038: Provide conversion helpers for struct __ntptimeval64
Those functions allow easy conversion between Y2038 safe, glibc internal

The reserved fields (i.e. __glibc_reserved{1234}) during conversion are
zeroed as well, to provide behavior similar to one in ntp_gettimex function
(where those are cleared before the struct ntptimeval is returned).

Those functions are put in Linux specific sys/timex.h file, as putting
them into glibc's local include/time.h would cause build break on HURD as
it doesn't support struct timex related syscalls.
