Don't trace or dump page fault records in the default set of tracepoints
as they can be quite noisy.

Requested by: Peter Jeremy
MFC after: 3 days

Add new ktrace records for the start and end of VM faults. This gives
a pair of records similar to syscall entry and return that a user can
use to determine how long page faults take. The new ktrace records are
enabled via the 'p' trace type, and are enabled in the default set of
trace points.

Tested with: make universe

Add a new type of KTRACE record for sysctl(3) invocations. It uses the
internal sysctl_sysctl_name() handler to map the MIB array to a string
name and logs this name in the trace log. This can be useful to see
exactly which sysctls a thread is invoking.

Spell -t option's argument by name.

Fix usage string.

This patch adds a new ktrace(2) record type, KTR_STRUCT, whose payload
consists of the null-terminated name and the contents of any structure
you wish to record. A new ktrstruct() function constructs and emits a
KTR_STRUCT record. It is accompanied by convenience macros for struct
stat and struct sockaddr.

In kdump(1), KTR_STRUCT records are handled by a dispatcher function
that runs stringent sanity checks on its contents before handing it
over to individual decoding funtions for each type of structure.
Currently supported structures are struct stat and struct sockaddr for
the AF_INET, AF_INET6 and AF_UNIX families; support for AF_APPLETALK
and AF_IPX is present but disabled, as I am unable to test it properly.

Since 's' was already taken, the letter 't' is used by ktrace(1) to
enable KTR_STRUCT trace points, and in kdump(1) to enable their
decoding.
