jdolecek a5ae7c6ca4 command(): don't start using procfs_getargv() instead of kvm_getargv()
just because the latter returned a NULL - that may normally happen,
when the process is, for example, a kernel thread

procfs_getargv(): if the name is brackened in '(' and ')', just
	return NULL immediately - the code in command() will DTRT
	and the output will be same for procfs- and kvm- based lookup
	in all cases

jdolecek e52880e76a getkinfo_kvm(): fix bug in previous - handled size_t i as if it would be signed
saveuser(): don't check kd - if we get here, kd is never NULL

jdolecek f848d2ec0c When using the procfs for extracting process information, extract
also process start time, process arguments and session leadership status.

The procfs fallback is also used when kvm_openfiles() completely fails
(e.g. when /dev/mem is not readable).

Solves PR 7772, though the final implementation is different.

bgrayson 05e0706ac9 Minor fixes:
1.  Use statfs() to verify that /proc is a procfs.
2.  Add -K option to disable /proc-based method.
3.  Make warnings less verbose, but still accurate.

bgrayson be8534f744 Added experimental fallback /proc-based lookup. Warnings are printed when the
fallback method is used, as the results could be untrustworthy if an
intruder is present.  It is highly likely that NetBSD-1.5 will have
an improved kvm interface for reading process information, at which
point this code can be garbage-collected.  Also added a word to the
man page -x option description while I was here.

kim 26cc4401e8 Fixed segfaulting for "ps -T". There is no optarg with -T, so instructions
under label "tty:" need to use ttname instead.

mrg 80efe80bc9 - change setgid kmem programs (that lend themselves to this) so setegid(getgid())
and the top, and then set the effective gid back to kmem around the call to
  kvm_openfiles().  this reduces the time group kmem is available.
- for those above that also allow this, setgid(getgid()) after the call to
  kvm_openfiles() to fully revoke priviledges.
- some KNF
- use err(3) over fprintf(3) in some places

cgd 40194b0e50 from Brian Somers <brian@awfulhak.demon.co.uk>:
The kvm entry isn't updated for command unless 'time' is given,
therefore
	ps -o command
outputs blank lines [or, in NetBSD, seg faults]
	ps -o time,command
works.
