Remove ancient SCCS tags from the tree, automated scripting, with two
minor fixup to keep things compiling. All the common forms in the tree
were removed with a perl script.

ktrace: Increase precision of timestamps.

Replace struct timeval in header with struct timespec.
To differentiate header formats, add a new KTR_VERSIONED flag
set in the header type field similar to the existing KTRDROP flag.

To make it easier to extend ktrace headers in the future,
extend the existing header with a version field (version 0 is
reserved for older records without KTR_VERSIONED) as well as
new fields holding the thread ID and CPU ID.

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

Add `-S' to display syscall numbers in the output as well.

This is useful for debugging compat modules.

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.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

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.

- Import the HEAD csup code which is the basis for the cvsmode work.

Spell -t option's argument by name.

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.

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.

Bump document date on behalf of the -E option.

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. :-)

Add a -E (elapsed time) flag to kdump. This is like -T, except it is

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.
