y2038: nptl: Convert pthread_cond_{clock|timed}wait to support 64 bit time

The pthread_cond_clockwait and pthread_cond_timedwait have been converted
to support 64 bit time.

This change introduces new futex_abstimed_wait_cancelable64 function in
./sysdeps/nptl/futex-helpers.c, which uses futex_time64 where possible
and tries to replace low-level preprocessor macros from
lowlevellock-futex.h
The pthread_cond_{clock|timed}wait only accepts absolute time. Moreover,
there is no need to check for NULL passed as *abstime pointer as
__pthread_cond_wait_common() always passes non-NULL struct __timespec64
pointer to futex_abstimed_wait_cancellable64().

For systems with __TIMESIZE != 64 && __WORDSIZE == 32:
- Conversions between 64 bit time to 32 bit are necessary
- Redirection to __pthread_cond_{clock|timed}wait64 will provide support
  for 64 bit time

The futex_abstimed_wait_cancelable64 function has been put into a separate
file on the purpose - to avoid issues apparent on the m68k architecture
related to small number of available registers (there is not enough
registers to put all necessary arguments in them if the above function
would be added to futex-internal.h with __always_inline attribute).

In fact - new function - namely __futex_abstimed_wait_cancellable32 is
used to reduce number of needed registers (as some in-register values are
stored on the stack when function call is made).

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

Above tests were performed with Y2038 redirection applied as well as without
to test the proper usage of both __pthread_cond_{clock|timed}wait64 and
__pthread_cond_{clock|timed}wait.

RISC-V: Use 64-bit time_t and off_t for RV32 and RV64

Using the original glibc headers under bits/ let's make small
modifications to use 64-bit time_t and off_t for both RV32 and RV64.

For the typesizes.h, here are justifications for the changes from the
generic version (based on Arnd's very helpful feedback):
- All the !__USE_FILE_OFFSET64 types (__off_t, __ino_t, __rlim_t, ...)
  are changed to match the 64-bit replacements.

- __time_t is defined to 64 bit, but no __time64_t is added. This makes
  sense as we don't have the time64 support for other 32-bit
  architectures yet, and it will be easy to change when that happens.

- __suseconds_t is 64-bit. This matches what we use the kernel ABI for
  the few drivers that are relying on 'struct timeval' input arguments
  in ioctl, as well as the adjtimex system call. It means that timeval
  has to be defined without the padding, unlike timespec, which needs
  padding.

Samuel Thibault [Wed, 5 Aug 2020 21:48:58 +0000 (23:48 +0200)]
hurd: Rework sbrk

Making the brk start exactly at the end of the main application binary was
requiring to get it through the _end symbol, which does not work any more
with recent toolchains, and actually produces in libc.so a confusing
external _end symbol that produces odd results, see
https://sourceware.org/bugzilla/show_bug.cgi?id=23499

Trying to do so is quite outdated anyway with the tendency for address
randomization.

Using _end was also allowing to include the main binary data within
the RLIMIT_DATA, but this also seems outdated with dynamic library
loading, and nowadays' memory consumption via malloc and mmap rather than
statically-allocated data.

This adds a BRK_START macro in <vm_param.h> that just tells where we
want to start the brk, and thus removes the _end symbol.

* sysdeps/mach/hurd/i386/vm_param.h: New file.
* sysdeps/mach/hurd/brk.c: Use BRK_START as brk start instead of _end.
