a56be37e68 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.

60e15db992 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.

Derived from patches by Andrew Li <andrew2.li@citi.com>.

a9ac598b36 Add a "-H" argument to kdump, which causes kdump to print an additional
field holding the threadid.  This is more useful for libthr than
libpthread, but still quite useful in libpthread as it can be used to
process interlaced records from multiple threads over the course of a
system call.

Detect old ktr_buffer values using the heuristic "if it's negative,
then it must not be a valid threadid".  This may leave something to be
desired.

24b648094d First pass at attempted debrucification:
- sort the -E switch into the right place.
- add previously missing -p pid in usage (from the last few commits).
- add -E to usage.
- consistently use trfile in the man page.

I knew I shouldn't have touched the man page.  If I commit to a man page,
it just makes people suspicious. :-)

ec13191464 Add a -E (elapsed time) flag to kdump. This is like -T, except it is
relative to start of the dump.

ec4beb5d8b Two enhancements for kdump.
1) add a "-p pid", which is rather useful for selecting a single pid in
a combined trace file (eg: with ktrace -i).
2) display binary genio data in a more precise format.
