msdos -> msdosfs.

- sys/msdosfs moved to sys/fs/msdosfs
- msdos.ko renamed to msdosfs.ko
- /usr/include/msdosfs moved to /usr/include/fs/msdosfs

$Id$ -> $FreeBSD$

Collapse the "get" code substantially by combining common functions.
Also make mountpoint for each media type easier to change.
Also reshuffled some menus for easier usage.

Check for C:\FREEBSD also, for backwards compatibility

Correct braino: msdos -> dos. Now DOS installations should work again
(cough).

Go back to using MSDOSFS instead of Robert Nordier's stand-alone DOS
library. I have to include MSDOSFS on the boot floppy anyway (so I can
read DOS floppies in a few other contexts) and since both -stable and
-current MSDOSFS handle long filenames, I'm OK on that now. Should
save about 10K of space.

Revert $FreeBSD$ to $Id$

Now that I know which parts of the installation really need it (since
there's no menu display bug to work around now), be far more selective
in my use of DITEM_RECREATE (which is slow and involves much screen I/O).

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.

Do a few things I've been threatening to do for a long time:

1. Don't use the MSDOSFS code for accessing FreeBSD distribution data.
Use Robert Nordier's stand-alone DOS I/O library for the purpose.
It this works as well as Robert says it does, it should drastically reduce
(or even eliminate) our "I can't install from my DOS partition!" calls.

2. As a result of the above, go to stdio file descriptors for all
media types.

3. Taking advantage of #2, start using libftpio for FTP transfers instead
of maintaining our own parallel version of the FTP transfer code.
Yay! I ripped something out for a change!

#1 Submitted-By: Robert Nordier <rnordier@iafrica.com>

Conditionalize some annoying debug statements, update the docs.

Whoops! Now that I'm decompressing docs into /tmp, it's important to
make sure that /tmp is there first! :-) While I'm at it, clean up the
somewhat inexplicably bogus Mkdir() function.

Fix an ancient index list bug.
Make FTP re-initializion work.
Fix fix fix.

Bring this into sync.

I still have a _very very annoying_ display bug which occurs when a menu
item causes a submenu to be displayed - the screen repaints for the original
menu (which is restored upon return from the submenu) are off by about 4
characters. I've tried restoring the screen, the cursor position, you name
it - same deal. Grrrr! This commit is my first step in trying to get someone
else to help me look into this one since I'm just tearing my hair out at this
point!

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.

Miscellaneous cleanup before big round of menu restructuring (to use new
libdialog features).

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...

Merge RELENG_2_0_5 into HEAD

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.

Humanize Poul-Henning's code. Status values should be properly
respected now.

Major cleanup. Mediaroutines now get asked about a file. All the
multi part stuff centralized.
The final check is backwards or something so it always said it failed,
even it it didn't.
Fixed tcpip address check to not be stupid, 10.0.255.1 is legal.

Things were getting seriously hard to find. Do a quick reorg pass over
the code and split things into more logical groupings.
