b3d01a2ad7 Fix warnings with lib/libpmc
* Use `MIN` instead of similar hand rolled macro.
* Sort headers.
* Use `errno.h` instead of `sys/errno.h`.
* Wrap the argument to sizeof in parentheses for clarity.
* Remove `__BSD_VISIBLE` and `_XOPEN_SOURCE` #defines to mute warnings about
  incompatible snprintf definitions.

This fixes a number of warnings I've been seeing lately in my builds.

Sort makefile variables per style.Makefile(9) (`CFLAGS`/`CWARNFLAG.gcc`) and
bump `WARNS` to 3.

2fa224b17d Fix get_maxfds() in jevents
If RLIM_INFINITY == -1ULL (such as on macOS) the min() call will result
in a value of less than 1 being returned. This causes nftw() to fail
with EINVAL.

While touching this file also fix includes to work on Linux/macOS and don't
declare snprintf since it may have different attributes in the system
headers there.

959826ca1b pmc(3)/hwpmc(4): update supported Intel processors to rely fully on the
vendor provided pmu-events tables and sundry cleanups.

The vendor pmu-events tables provide counter descriptions, default
sample rates, event, umask, and flag values for all the counter
configuration permutations. Using this gives us:

- much simpler kernel code for the MD component
- helpful long and short event descriptions
- simpler user code
- sample rates that won't overload the system

Update man page with newer sample types and remove unused sample type.
