Add support for timeconting in userland.2020-07-06T13:33:05Zpiroftipirofti@openbsd.org2020-07-06T13:33:05Zurn:sha1:d82e6535c6efd8305182f77041b2246ccfae1196
This diff exposes parts of clock_gettime(2) and gettimeofday(2) to
userland via libc eliberating processes from the need for a context
switch everytime they want to count the passage of time.
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!

Stop exporting the internal _mcount symbol as that's only referenced2019-10-26T18:47:10Zguentherguenther@openbsd.org2019-10-26T18:47:10Zurn:sha1:589b4acdbba65d6ecc6e77d9aac5e27618bc75fb
by the ASM stub, which is also in libc. The compiler only generates
invocations of the latter.

Clear the sign bit in the QNAN constants used by strtof, strtod and strtold,2018-05-28T03:20:25Zjmatthewjmatthew@openbsd.org2018-05-28T03:20:25Zurn:sha1:4f3262728f75ab09c39d31185a1ebdf9938b762e
so passing "nan" and "-nan" produces a NaN with the right sign.

Instead of trying to handle ffs() with the normal rename-mark-hidden-and-alias2018-01-18T08:23:44Zguentherguenther@openbsd.org2018-01-18T08:23:44Zurn:sha1:ae3cb403620ab940fbaabb3055fac045a63d56b7
dance, mark it protected. This works better for both gcc and clang: gcc
blocks overriding of internal calls, while clang permits inlining again.

easier to review the substantive diffs.
