Now that time_t is unconditionally 64-bit (signed int64_t) and the
struct timespec fields tv_sec / tv_nsec are wide enough on their own,
the explicit (uint64_t)/(int64_t)/(int) casts that used to guard the
multiplications and subtractions in *_us / *_ms / *_ns helpers are no
longer needed. Drop them to keep the timekeeping math readable and
consistent with the previous sclock_t/time_t cleanup.
In the same spirit, this commit also:
* Normalises the printf-style format specifiers and casts used to
print tv_sec / tv_nsec / tv_usec values across arch/, drivers/,
fs/, sched/ and libs/. The prior code was a mix of
"%d"/"%u"/"%ld"/"%lu"/"%lld"/PRIu32/PRIu64 with matching
(int)/(unsigned long)/(long long)/PRIu* casts; some formats
truncated time_t on 32-bit hosts, others mismatched signedness or
width. Replace all such cases with the portable POSIX-recommended
forms:
- tv_sec (time_t, signed, impl-defined width) -> %jd + (intmax_t)
- tv_nsec (long, signed) -> %ld (no cast)
- tv_usec (suseconds_t / long) -> %ld (no cast)
Add #include <stdint.h> where required.
* Drops a few stale `(FAR const time_t *)&ts.tv_sec` casts and
related `(FAR struct tm *)` / `(const time_t *)` casts in
gmtime_r() / localtime_r() / gmtime() callers; ts.tv_sec is plain
time_t now and the casts only obscured the type.
* Fixes one overflow in fs/procfs/fs_procfscritmon.c where
all_time.tv_sec * 1000000 could overflow on 32-bit time_t before
being multiplied again; cast to uint64_t at the start.
No behavioural change.
