hwpmc(4): update DEBUGGING section details

The examples I wrote previously do not work. We parse the flags using
explicit names, not the shortened flag suffix. Fix the list of major
flags, and add a compact list of minor flags. Fix the examples, and
tweak some wording for clarity.

hwpmc(4): document debugging options

The debug options for hwpmc are not documented in detail anywhere, and
setting it up was error-prone the first time I had to figure it out (and
each time I've had to remember it). Add some explanation of the required
options and describe the kern.hwpmc.debugflags sysctl format.

pmc: Initialise and check the pm_flags field for CONFIGURELOG

Whilst the former is not breaking, the latter is, and so this will be
followed by a bump to the pmc major version. This will allow the flags
to actually be usable in future, as otherwise we cannot distinguish
uninitialised stack junk from a deliberately-initialised value.

hwpmc: Permit the minimum sampling count to be set as a sysctl.

A rarely occurring event (e.g. an event that occurs less than 1000
times during execution of a program) may require a lower minimum
threshold than 1000. Replace the hardcoded 1000 with a sysctl that
the administrator can use to permit smaller sampling count values.
