MFC r286701:
If a specific timecounter has been chosen via sysctl, and a new
timecounter with higher quality registers (presumably in a module that has
just been loaded), do not undo the user's choice by switching to the new
timecounter.
Document that behavior, and also the fact that there is no way to
unregister a timecounter (and thus no way to unload a module containing
one).

MFC r279728, r279729, r279756, r279773, r282424, r281367:
Add mutex support to the pps_ioctl() API in the kernel.
Add PPS support to USB serial drivers.
Use correct mode variable for PPS support.
Switch polarity of USB serial PPS events.
The ftdi "get latency" and "get bitmode" device commands are read
operations, not writes.
Implement a mechanism for making changes in the kernel<->driver PPS
interface without breaking ABI or API compatibility with existing drivers.
Bump version number to indicate the new PPS ABI version changes in the
pps_state structure.

MFC 276724:
On some Intel CPUs with a P-state but not C-state invariant TSC the TSC
may also halt in C2 and not just C3 (it seems that in some cases the BIOS
advertises its C3 state as a C2 state in _CST). Just play it safe and
disable both C2 and C3 states if a user forces the use of the TSC as the
timecounter on such CPUs.
