GCC's default visibility is "public" but can be changed to
"hidden" with the argument "-fvisibility=hidden".
Tested with x86_64 / Ubuntu Linux 18.04 LTS:
[before]
$ nm -g -C libmimalloc.so | grep "T " | wc -l
142
[after]
$ nm -g -C libmimalloc.so | grep "T " | wc -l
93
This patch does not change the build on macOS.
clock_gettime(CLOCK_REALTIME, &ts) is equivalent to timespec_get(&ts,
TIME_UTC) in C11.
It has the advantage that avoids the following building error when building
with macOS:
warning: 'timespec_get' is only available on macOS 10.15 or newer
[-Wunguarded-availability-new]
GCC does want to complain about parameter-less functions declared
without the recommended `void` as parameter list.
