If a timecounter clock can be exposed to userland than it needs to set its tc_user member to a non-zero value. Tested with one or multiple counters per architecture. The timing data is shared through a pointer found in the new ELF auxiliary vector AUX_openbsd_timekeep containing timehands information that is frequently updated by the kernel. Timing differences between the last kernel update and the current time are adjusted in userland by the tc_get_timecount() function inside the MD usertc.c file. This permits a much more responsive environment, quite visible in browsers, office programs and gaming (apparently one is are able to fly in Minecraft now). Tested by robert@, sthen@, naddy@, kmos@, phessler@, and many others!

Then in _csu_finish(), invoke the dl_clean_boot() callback to free ld.so's startup bits before main() gets control. Other cleanups this permits: - move various startup structures into .data.rel.ro - the dl* stubs in libc can be strong and call the callbacks provided via _dl_cb - no longer need to conditionalize dlctl() calls on presence of _DYNAMIC original concept and full diff ok kettenis@ ok deraadt@ 2019-05-10T15:03:24Z otto otto@openbsd.org 2019-05-10T15:03:24Z urn:sha1:e03a31515fc3008507a9ab3997d0ac6226da8bb6 counterparts but return memory in pages marked MAP_CONCEAL and on free() freezero() is actually called. 2019-01-12T00:16:03Z jca jca@openbsd.org 2019-01-12T00:16:03Z urn:sha1:13e54a3ce65615faaf13e4717a510eb52bfb2efe POSIX wants it in libc, that's where the function can be found on other systems.
