kdump.1: use past tense for history

Add comma in enumeration.

Note ioctlprint(1) in SEE ALSO

Sort flags in SYNOPSIS. Remove unnecessary .Tn. Remove trailing whitespace.

Option name from FreeBSD. While here, make it possible to use a
combination of -T -E and -R to display timestamps in several formats.

New sentence, new line; add comma in enumeration.

Following mycroft's comment, restore -x to its original behavior: without
an argument. Introduce -Xsize to do the job. -x is equivalent to -X1
Of course -x and -Xsize are mutually exclusive.

Bump date for previous. New sentence, new line.

Add an argument to the -x flag to choose between byte per byte display
and word per word display in hex dumps.
-x1 gives you byte per byte, -x4 word per word, and -x defaults to -x1

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22365, verified by myself.

Grok KTR_EXEC_ENV and KTR_EXEC_ARG.
Make ktrace -c default to removing all trace points (not just the default ones).
Make kdump default to dumping everything in the trace file.
Add 'A' (all) and '-'

Grok KTR_EXEC_ENV and KTR_EXEC_ARG.
Make ktrace -c default to removing all trace points (not just the default ones).
Make kdump default to dumping everything in the trace file.
Add 'A' (all) and '-' (remove following) to valid -t arguments.
Dump data block of UNKNOWN trace points in hex + ascii.
Make first time output with -R 0 (instead of time since epoch).
Use svis() instead of vis() to get " escaped (as \") (needs fixed libc)
Correctly pass unsigned values to svis()
Update man pages.

Bump date for -x addition.

Add a '-x' option to display GIO data blocks in hex and ascii (instead of
vis(3) format).
Maybe there could be a heuristic to decide whether the data is printable...

Back out previous.

add appropriate hack to display ktr_buf as the lwpid if -L is supplied on
the command line.

.Nm does not need a dummy argument ("") before punctuation or
for correct formatting of the SYNOPSIS any longer.

Bump date for -N; sort options.

Add -N which inhibits translation of system calls numbers into names.

Bump date for .Op Ar file addition.

Allow passing of the ktrace file as the last argument without a -f.

It's easy for ktrace can generate trace files that contain data from
multiple processes, so let's add a "-p pid" option to kdump so that it
can pull out the data for one process easily.

Whitespace cleanup.

use 'trstr' for parameter to -t; both 'cenis' (SYNOPSIS) and 'cnis' (DESCRIPTION)
were already out of date and we really don't want keep the info on two
places

clarify -e usage

More and more .Os cleanups. .Os is defined in the tmac.doc-common file,
so we shouldn't override it with versions in the manpages. Many more to
come.
