[PATCH v2 0/4] c2y proposal add monotonicwait support for mtx and ctx

[Yonggang Luo]

For c11 threads, the mtx and cnd doesn't support for monotonic timedlock and timedwait;
So add two proposal function mtx_timedlock_base cnd_timedwait_base to do that.
The protype of these two functions is:

int mtx_timedlock_base(mtx_t *restrict m, int time_base, const struct timespec *restrict ts);

int cnd_timedwait_base(cnd_t *restrict c, mtx_t *restrict m, int time_base, const struct timespec *restrict ts);

The time_base at least can be TIME_UTC/TIME_MONOTONIC, the implementer can implement it with any provided
TIME_* base parameter provided in c2y time.h, if TIME_MONOTONIC can not natively supported, fallback to TIME_UTC
should provided, for other TIME_* base parameter, it's implementer's choice.

Yonggang Luo (4):
  clang-format: should format with 2 space and do not usage tab
  time: Implement c23 timespec_get base
  c11: Switch to use pthread_mutex_clocklock and pthread_cond_clockwait
    to implement cnd and mtx lock and wait
  c2y: Add function cnd_timedwait_base and mtx_timedlock_base
