276de18cc9 Fill in the some new fields 'struct kinfo_proc', namely ki_childstime,
ki_childutime, and ki_emul.  Also uses the timeradd() macro to correct
the calculation of ki_childtime.  That will correct the value returned
when ki_childtime.tv_usec > 1,000,000.

This also implements a new KERN_PROC_GID option for kvm_getprocs().
It also implements the KERN_PROC_RGID and KERN_PROC_SESSION options
which were added to sys/kern/kern_proc.c revision 1.203.

d688cb4c0d Add some more fields to the 'struct kinfo_proc', including some fields
which just mark areas which are empty due to issues with the alignment
of already-existing fields.  This defines several unrelated variables
in one shot, because most of the work for updating kinfo_proc is making
sure the sizeof(struct kinfo_proc) remains the same across all hardware
platforms, and that no space is wasted on any platform due to alignment
issues with the new variables.

83cca9682f Removed foot-shooting setting of CR0_TS in exec_setregs(). It is
unnecessary because cpu_setregs() and/or npxinit() always sets CR0_TS
during system initialization, and CR0_TS is set in the next statement
(fpstate_drop()) if necessary after system initialization.  Setting
it unnecessarily was less than a pessimization since it broke the
invariant that the npx can be used without an npxdna() trap if
fpucurthread is non-null.  The broken invariant became harmful when I
added an fnclex to npxdrop().

Removed setting of CR0_MP in exec_setregs().  This was similarly
unnecessary but was harmless.

Updated comments (mainly by removing them).  Things are simpler now
that we have cpu_setregs() and don't support a math emulator or pretend
to support not having either a math emulator or an npx.

Removed the ifdef for avoiding setting CR0_NE in the !SMP case in
cpu_setregs().  npx_probe() should reverse the setting if it wants to
force IRQ13 exception handling for testing.

5ff798ca5f Fix the check for a "duplicate filename to compress", so that we're checking
the *filename* and not the pid_file(!).   Stupid brain-fault on my part.
This could cause a segfault under -neworder if newsyslog had to rotate
multiple files, and later ones had specifed the 'N' flag.

2a6bf1fadb Memory's free, but all the world ain't a VAX anymore. Bring math.3
kicking and screaming into the 1980's.  This change converts most of
the markup from man(7) to mdoc(7) format, and I believe it removes or
updates everything that was flat out wrong.  However, much work is
still needed to sanitize the markup, improve coverage, and reduce
overlap with other manpages.  Some of the sections would better belong
in a philosophy_of_w_kahan.3 manpage, but they are informative and
remain at least as reminders of topics to cover.

31f555a1c5 Assert socket buffer lock in sb_lock() to protect socket buffer sleep
lock state.  Convert tsleep() into msleep() with socket buffer mutex
as argument.  Hold socket buffer lock over sbunlock() to protect sleep
lock state.

Assert socket buffer lock in sbwait() to protect the socket buffer
wait state.  Convert tsleep() into msleep() with socket buffer mutex
as argument.

Modify sofree(), sosend(), and soreceive() to acquire SOCKBUF_LOCK()
in order to call into these functions with the lock, as well as to
start protecting other socket buffer use in their implementation.  Drop
the socket buffer mutexes around calls into the protocol layer, around
potentially blocking operations, for copying to/from user space, and
VM operations relating to zero-copy.  Assert the socket buffer mutex
strategically after code sections or at the beginning of loops.  In
some cases, modify return code to ensure locks are properly dropped.

Convert the potentially blocking allocation of storage for the remote
address in soreceive() into a non-blocking allocation; we may wish to
move the allocation earlier so that it can block prior to acquisition
of the socket buffer lock.

Drop some spl use.

NOTE: Some races exist in the current structuring of sosend() and
soreceive().  This commit only merges basic socket locking in this
code; follow-up commits will close additional races.  As merged,
these changes are not sufficient to run without Giant safely.
