dot.profile: handle symlinked $HOME

Reapply 4cea05a273c875b5d5d4c41bfa6f2f0a60fa4a66:

Make sh(1) recognize the default $HOME. By default /home
is a symlink; without this change, when you log in, sh(1)
won't realize the current directory (eg '/usr/home/test')
is the same as $HOME ('/home/test').

/home is no longer a symlink by default, but new users may be added on
systems that started out with an earlier version of FreeBSD (and still
have /home as a symlink) or admins may do so.

This test is not particularly expensive, so just restore it.

.profile: Don't bother checking for /home symlink

Since FreeBSD 14.0, user directories are created directly under /home.
This check should no longer be needed.

This reverts commit 4cea05a273c875b5d5d4c41bfa6f2f0a60fa4a66.

Remove $FreeBSD$: one-line sh pattern

Remove /^\s*#[#!]?\s*\$FreeBSD\$.*$\n/

Don't mess with BLOCKSIZE in shell startup files - it's set by login.conf(5);
there's no need to even mention it in shell rc files. Not that it's wrong;
just pointless and somewhat misleading.

Cosmetic tweaks to the default shell rc files, mostly comments.

MFC after: 2 weeks

Run "resizewin -z" from the default shell profile files. This makes
the terminal work properly out of the box when logging over a serial
line, which is quite important for the user experience on boards like
Raspberry Pi. It doesn't affect cases where the terminal size is
already non-zero, such as SSH or vt(4) sessions.

Note that this doesn't handle a scenario pointed out by rgrimes@:
when the terminal is resized after login, the terminal size won't
get updated even after logging out and back in.

Step 1 of eliminating the "games" distribution: Move binaries to /usr/bin;
update paths; and include everything in the "base" distribution.

The "games" distribution being optional made sense when there were more
games and we had small disks; but the "games-like" games were moved into
the ports tree a dozen years ago and the remaining "utility-like" games
occupy less than 0.001% of my laptop's small hard drive. Meanwhile every
new user is confronted by the question "do you want games installed" when
they they try to install FreeBSD.

The next steps will be:

2. Removing punch card (bcd, ppt), phase-of-moon (pom), clock (grdc), and
caesar cipher (caesar, rot13) utilities. I intend to keep fortune, factor,
morse, number, primes, and random, since there is evidence that those are
still being used.

3. Merging src/games into src/usr.bin.

This change will not be MFCed.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

Switch the default terminal emulation style to xterm for most platforms.

Right now syscons(4) uses a cons25-style terminal emulator. The
disadvantages of that are:

- Little compatibility with embedded devices with serial interfaces.
- Bad bandwidth efficiency, mainly because of the lack of scrolling
regions.
- A very hard transition path to support for modern character sets like
UTF-8.

Our terminal emulation library, libteken, has been supporting
xterm-style terminal emulation for months, so flip the switch and make
everyone use an xterm-style console driver.

I still have to enable this on i386. Right now pc98 and i386 share the
same /etc/ttys file. I'm not going to switch pc98, because it uses its
own Kanji-capable cons25 emulator.

IMPORTANT: What to do if things go wrong (i.e. graphical artifacts):

- Run the application inside script(1), try to reduce the problem and
send me the log file.
- In the mean time, you can run `vidcontrol -T cons25' and `export
TERM=cons25' so you can run applications the same way you did before.
You can also build your kernel with `options TEKEN_CONS25' to make all
virtual terminals use the cons25 emulator by default.

Add explicit test so that non-existence of /usr/games/fortune
doesn't affect command exit status.

- Import the HEAD csup code which is the basis for the cvsmode work.

Revert $FreeBSD$ to $Id$

Various sanitizations:

. Don't clobber the TERM setting; it's supposed to be done by /etc/ttys
already.
. Comment out the Interviews stuff, 98 % of all users probably won't
ever use it.
. Install the files with better default permissions in the skeleton
directory; pw(8) retains the permissions when creating a new
acount, and installing them read-only is stupid, yet installing
.rhosts world-readable is dangerous.

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.

Similarly spartan dotfiles.

on.

Make the default paths a bit more rational for our systems (sheesh!).
