debugMsg() should end with "\n".

Silence warnings on alpha :

Use '%p' when printing out the address of a function.
sizeof(int) != sizeof(long)

Mark relevant functions __printflike()/__printf0like() and silence some of
the non-constant format string warnings.

$Id$ -> $FreeBSD$

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

1. Update all the copyrights to delete useless clauses 3 and 4.
2. Change more of the menu code over to new system.
3. Streamline label editor.

Update the -current sources from the 2.1 branch.

This mega-commit brings in Jordan's latest sysinstall version..
This looks like it was developed offline, and is being spammed over the
top of the existing. "That's fine by me! I dont really care how you do
it, just get it in there..." said Jordan in a conversation a short while
ago...

Remove trailing whitespace.

Sync up my work for the night. This should implement ALL possible
installation methods and provide a fairly robust set of menu options.
This should also fix a few more bugs on Poul-Henning's latest gripe
list.

Clear the screen on msgNotifys.
Don't notify in vsystem() - it obscures the original message.
Put some debugging code into cpio_extract() so that I can see
why it doesn't work now. :(

More assorted verbosity. Also don't log informational messages.

Sigh. Add a ++ which was causing the newfs'ing of non-root filesystems to
fail :-(

1. Primitive bad144 support (I believe an additional command is needed, but
won't know until Poul wakes up again).
2. Make vsystem() put its output on the debugging fd.
3. DTRT with root filesystem placement - now I see how this has to work
(thanks, Poul).
4. Many miscellaneous spelling errors fixed and general cleanup.

Use my own version of system() everywhere - it knows where to find the
shell!

This will now compile and even scribble helpfully on your disks.
It remains to be seen how successfully. The distribution loading code
is still not here yet, but the partition/newfs/mount/cpio-extract cycle
is as complete as it's ever going to get, modulo possible bug fixes.
The TCP/IP setup screen is also sort of here, albeit in a highly-changing
state due to the fact that per-interface information isn't being kept
right now but is being added (thanks, Gary!).

This does _not yet compile_; I'm simply bringing in my changes from
this weekend in order to more easily sync with my CVS tree at home.
Another commit relative to these changes will follow shortly.

1. Don't check CHUNK_BSD_COMPAT for now; it always returns "no" and is
getting in the way of testing right now.
2. Call system() on commands, not vsystem(). No need for vsystem() here.
3. Add a path for the shell.

Add the sorted command executor code.
