- release/* update to use freebsd-doc-* packages instead of building
FreeBSD docset during 'make release' this will speed up release
builds;
- sysinstall(8) has also been updated to use these packages with a new
menu allowing people to choose what localized doc to install;
- mention in UPDATING that docs from the FreeBSD Documentation project
are now installed in /usr/local/share/doc/freebsd instead of
/usr/share/doc.

s/package_exists/package_installed/g as that's much more descriptive of
what the function does.

Fix links to the FAQ and the Handbook

Change the name of the 'bin' distribution to 'base'.
This is done since it contains much more than /bin, and also gets in the
way when making a combined install+fixit CD.

Fix benign but stupid variable typo.

Make the doc menu work again by checking the right variables.

Whoops, I broke the doc browser (not that anyone would notice since nobody
READS the docs, but anyway.. :). Fix it.

Completely rip-out and redesign sysinstall's refresh model as well
as redoing all the menus to have proper, or at least non-hallucinogenic,
keyboard accelerators.

This requires my recent update to libdialog to work properly and will
probably also exhibit some other "interesting" behavior while the last
few missing screen clears are found (which is why I'm not going to MFC
immediately). At least now, however, sysinstall does not gratuitously
redraw random screens at the drop of a hat and drive serial console
installers out of their minds.

Update for new doc paths.

$Id$ -> $FreeBSD$

Correct bogus msg dialog.
Update to Lynx 2.7 (need to build 2.1/2.2 versions of this package).

It's easier to go forwards than backwards with this, and the RELENG_2_1_0
sysinstall was already broken (I think there's a PR for this somewhere).
This will require some additional changes elsewhere, like bringing in pw.

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.

fix FAQ URL. Note for Jordan: don't merge this change into 2.1.6!

Support compressed doc files again.
Add a few strategic screen clears.
Do a lot less wasted screen I/O in restoring screen contents that don't need
restoring.
Use tar instead of cp to back up /etc in installUpdate.
Don't panic when upgrade shell exits.

Make it plainer how to exit.

Fix some long-standing malloc bugs in the package handling code (freeing garbage
in one place, leaking memory in another).

Add a facility to invoke subsystems directly by naming them on
sysinstall's command-line when running post-install. A replacement
for pkg_manage might, for example, be `/stand/sysinstall configPackages'

Fix bogon where upgrade shell was entered with tty modes spammed.

Fix bug with release name checking in ftp_strat. Turned a bunch of
bogus exit()s into proper calls to systemShutdown().

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

Quite a few changes:

1. Fix the last display bugs (I hope) by use of dialog rebuilds at stategic
points.
2. Clean up the distributions menus so that everybody (that's reasonable)
has All and Clear options for setting/clearing things en-masse.
3. Various attempts at display optimization.
4. Change the wording of the `Don't use Write!' dialogs to make them more
explicitly define when and when not to use the option.

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.

Major surgery.

1. Use new dialog menu hacks (no strings, just arrays of dialogMenuItem structs)
so that I can create composite menus with radio/checkbox/... items in them,
removing some long-standing UI bogons in various menus. This work isn't
finished yet, but will be done in two phases. This is phase one.

2. Remove all the script installation stuff. I never got time to document it,
it was arcane and it just complicated much of the code. There are better
ways of doing this if I want to do auto-driven installations later.

3. Remove much dead code and otherwise attempt to remove as much historical
grot as possible so that this code is easier to hack on. This is also
a two-stage process, phase one of which is now complete.

Some general fixes for the package menu (still need to fix the "more than 10
items checked bug though). Now allow user to specify a PKG_TMPDIR. If
not selected, we try to make one.

Various tweaks to adjust things more to my liking. Also bring in Rich's
changes to update XFree86 to 3.1.2-S.

Be more aggressive about writing out configuration files.

Fix the bug I introduced with /etc/sysconfig not being updated
properly.
Make some cosmetic doc changes here and there in response to user
feedback.

Sync up for this snapshot.

Second round of screen update changes. Now handle the yes/no dialogs
as well as the confirmation dialogs.

Style changes. Clear the screen before a lot of error dialogs so that they
don't bogusly restore the screen to the message that was the cause of the
abort. That resulted in lots of weird flickering dialog boxes that appeared
to be displayed out of sequence.

Style police throughout.
Fix the ppp startup code.
Make the disklabel and fdisk screens "automatable"

Sync for Westhill build.

Finally split this off from system.c, as intended.
