38a9346b2f Switch procstat from subcommand flags to verbs
- Use an enumerated value instead of separate flags for commands
- Look for a verb if no command flag is set
- Lookup the "xocontainer" value based on the command
- Document the new command verbs in the man-page

533491cf99 Make procstat(1) recognize process descriptors, so that it shows
"P" instead of "?" in "procstat -af" output. Note that there are
still a few more DTYPE_* kinds we don't decode yet.

f90116537f Start writing up some basic feature tests for procstat
These tests query a running process for information related to the -b,
-c, -e, and -f flags; the -f testcase is largely stubbed out, pending
additional work to determine a good, deterministic descriptor.

Core file test support is coming soon--it requires a bit more effort
due to the fact that:
- coredumps can be disabled (kern.coredump=0).
- corefiles can be put in different directories than the current
  directory, or be named something other than `<prog>.core`
  (`kern.corefile`).

- Fix a typo (SIGIGN -> SIG_IGN). Use .Dv when referencing SIG_IGN.
- Use semi-colons as soft breaks when separating sentences for
  the FLAGS section.
- Tweak wording for C slightly to flow better and to be a bit
  more technically correct (signals with handlers installed will
  be caught by the target program).
- Reference signal(3) in the SEE ALSO section.

I will handle separately.  Bump __FreeBSD_version.

066f63003b Decompose linkat()/renameat() rights to source and target.
To make it easier to understand how Capsicum interacts with linkat() and
renameat(), rename the rights to CAP_{LINK,RENAME}AT_{SOURCE,TARGET}.

This also addresses a shortcoming in Capsicum, where it isn't possible
to disable linking to files stored in a directory. Creating hardlinks
essentially makes it possible to access files with additional rights.

- Add an -H flag to request information about threads rather than processes

  resource usage for individual threads instead of the entire process.

6175f0915f Replace CAP_POLL_EVENT and CAP_POST_EVENT capability rights (which I had
a very hard time to fully understand) with much more intuitive rights:

	CAP_EVENT - when set on descriptor, the descriptor can be monitored
		with syscalls like select(2), poll(2), kevent(2).

	CAP_KQUEUE_EVENT - When set on a kqueue descriptor, the kevent(2)
		syscall can be called on this kqueue to with the eventlist
		argument set to non-NULL value; in other words the given
		kqueue descriptor can be used to monitor other descriptors.
	CAP_KQUEUE_CHANGE - When set on a kqueue descriptor, the kevent(2)
		syscall can be called on this kqueue to with the changelist
		argument set to non-NULL value; in other words it allows to
		modify events monitored with the given kqueue descriptor.

Add alias CAP_KQUEUE, which allows for both CAP_KQUEUE_EVENT and
CAP_KQUEUE_CHANGE.

Add backward compatibility define CAP_POLL_EVENT which is equal to CAP_EVENT.

734382a525 Add a resource limit for the total number of kqueues available to the
user.  Kqueue now saves the ucred of the allocating thread, to
correctly decrement the counter on close.

Under some specific and not real-world use scenario for kqueue, it is
possible for the kqueues to consume memory proportional to the square
of the number of the filedescriptors available to the process.  Limit
allows administrator to prevent the abuse.

This is kernel-mode side of the change, with the user-mode enabling
commit following.
