commit f4d6ef2d417e0fc10a159ab64827f837c9a3be84

time.h: Introduce Linux-specific CLOCK id values
- Add CLOCK_REALTIME_COARSE, CLOCK_MONOTONIC_RAW,
CLOCK_MONOTONIC_COARSE and CLOCK_BOOTTIME
- Guard new values with __GNU_VISIBLE
- Add CLOCK_REALTIME_COARSE as (clockid_t) 0 for simplicity
(It allows to have all values < 8 and so be used as array
index into an array of clocks)
- Fix macro bracketing
