Add '-c' option to gen_initramfs.sh to choose the compression type.
Currently, it supports the following types: gzip (default), bzip2, lzma,
and none.

The toplevel Makefile now has a variable to specify the compression type
of the initramfs, and passes it to gen_initramfs.sh.  Currently it is
set to lzma by default.

The following components of the Linux MFS were updated:

Linux kernel => 2.6.32.9
buildroot => 2010.02
uClibc => 0.9.30.2
busybox => 1.16.0
binutils => 2.20
gcc => 4.2.4
gmp => 4.2.4

The Dell Optiplex reboot patch was removed from the kernel build as it
is already present in 2.6.32.9.

The update was done because:
- The kernel was over a year old and significant updates have happened
  since then.
- A few new useful features were added to busybox
- The kernel now supports bzip2 and lzma compression for itself and
  initramfs in addition to gzip.  Using lzma instead of gzip saves us at
  least 1.5 MB for the kernel+initramfs, possibly more.

The toolchain build should be dependent on an actual file to ensure we
don't rebuilt it for every target that goes into the initramfs.

Also rename old fake tcsh to tcsh.fake, and run a new script that
symlinks tcsh and csh to tcsh.fake if tcsh doesn't exist.  This way tcsh
can be removed from the build but tcsh/csh users can still log in.

Added a makefile to build the toolchain via buildroot.  Everything now
depends on the toolchain having been built, so a simple 'make' should
build everything.

Added patches to change getline() to _getline() in Linux's and uClibc's
unifdef build utility.  This fixes compile errors on recent glibc
versions that define their own getline() function.

Kernel modules are now compressed into a tarball in addtion to being
installed into the initramfs.  This way all modules are still available
even if modules are removed from the initramfs to reduce its size.

The final initramfs image is now located in $(TOPDIR) along with the
kernel and modules tarball.

- Cleanup of filesystem layout
- Some patches to make busybox's adduser and addgroup commands a bit more
  compatible with the standard useradd and groupadd commands
- Wrappers for ((user|group)(add|del))
- Getopt perl module added
- Working sudo setup
- Portmap added to support NFS mounts with locking.
- Syslog added, but not currently configured. Primarily intended for
  troubleshooting strange problems.
- Fixes to permissions
- rc.mounts, rc.localize, and rc.accounts work now.

- /usr/bin/perl is only 850K (due to being linked against uClibc)
- 99.572% of test cases pass (some Embed tests and pwent/grent tests fail)
- First pass at installing only modules we need: /usr/lib/perl5/5.88
  is only 1.2 meg decompressed.

- Added iPOD, o745-reboot, and bsdlabel kernel patches
- Updated kernel config

- New versions of linux, busybox, buildroot, hdparm, etc.
- Moved target_template to source tree
- Cleaned up makefiles

Finally committed all of my Linux MFS stuff.  It's not done yet, but enough is there that I need to get it into version control before I lose it.

This includes:
- Build tree for a Linux frisbee MFS (the source tarballs are in ops:/share/linux/mfs/source)
- Patch for pxelinux to add bootinfo support
- Patch for grub to support our magic config sector
