6aed20fe1a Remove unused variables.
Simply annotate the function parameters with __unused, instead of adding
the ve-variables. This makes the code build with GCC 4.7 and -Werror.

2d455a01bd Tweaks to ps(1):
- there's no reason the semantics of the -x flag are being explained in
  the -a flag description
- be more precise regarding the relation between the -a flag and the
  security.bsd.see_other_uids sysctl
- describe the format of the -t flag's argument
- 'con' no longer is a possible entry in the 'TT' column
- explain that the 'TT' column refers to pseudo-terminals via mere numbers
- add a hint in the 'tt' keyword description that a keyword 'tty' exists,
  which will give the full terminal pathname

9f365aa1d6 Get rid of major/minor number distinction.
As of FreeBSD 6, devices can only be opened through devfs. These device
nodes don't have major and minor numbers anymore. The st_rdev field in
struct stat is simply based a copy of st_ino.

Simply display device numbers as hexadecimal, using "%#jx". This is
allowed by POSIX, since it explicitly states things like the following
(example taken from ls(1)):

	"If the file is a character special or block special file, the
	size of the file may be replaced with implementation-defined
	information associated with the device in question."

This makes the output of these commands more compact. For example, ls(1)
now uses approximately four columns less. While there, simplify the
column length calculation from ls(1) by calling snprintf() with a NULL
buffer.

Don't be afraid; if needed one can still obtain individual major/minor
numbers using stat(1).

4610a8114d [1] When showing threads, the thread name just appears if the comm
label is choosen as last printout (ucomm suffers of this such bug
	too).  That bug is caused by the fact that the fixed size of
	printout doesn't leave enough space for them to be printed out.
	Implement ucomm and comm commands with a dynamic size lenght for
	buffers.

[2]	On AMD64 architecture pointers don't have enough chars space to
	be shown (8 chars while they need 16).  Fix them by providing
	a variadic space so that it fits well on both 64 and 32 bits
	architectures.

[3]	Check a return value of malloc() that wasn't checked before.

7ab24ea3b9 Introduce a way to make pure kernal threads.
kthread_add() takes the same parameters as the old kthread_create()
plus a pointer to a process structure, and adds a kernel thread
to that process.

kproc_kthread_add() takes the parameters for kthread_add,
plus a process name and a pointer to a pointer to a process instead of just
a pointer, and if the proc * is NULL, it creates the process to the
specifications required, before adding the thread to it.

All other old kthread_xxx() calls return, but act on (struct thread *)
instead of (struct proc *). One reason to change the name is so that
any old kernel modules that are lying around and expect kthread_create()
to make a process will not just accidentally link.

fix top to show  kernel threads by their thread name in -SH mode
add a tdnam formatting option to ps to show thread names.

make all idle threads actual kthreads and put them into their own idled process.
make all interrupt threads kthreads and put them in an interd process
(mainly for aesthetic and accounting reasons)
rename proc 0 to be 'kernel' and it's swapper thread is now 'swapper'

man page fixes to follow.

b61ce5b0e6 - Move all of the PS_ flags into either p_flag or td_flags.
- p_sflag was mostly protected by PROC_LOCK rather than the PROC_SLOCK or
   previously the sched_lock.  These bugs have existed for some time.
 - Allow swapout to try each thread in a process individually and then
   swapin the whole process if any of these fail.  This allows us to move
   most scheduler related swap flags into td_flags.
 - Keep ki_sflag for backwards compat but change all in source tools to
   use the new and more correct location of P_INMEM.
