Subject: user-mode port 0.40-2.4.3

The user-mode port of 2.4.3 is available.

Added --help and --version, which do the obvious things

UML now creates a /tmp/uml/<name> pid file. The name can be set with the
'-umid=<name>' switch. This is intended to make it easier for a UI to control
a number of virtual machines. There is a more general interface coming which
will replace the pid file with a socket to a low-level console inside UML.

Fixed several major crashes and numerous smaller bugs. The major fixes
required some surgery from which UML still hasn't totally recovered, so it's
still a bit wobbly. In particular, if it swaps, processes will start
segfaulting, and the swap code will start spitting out various
frightening-sounding messages.

A number of hostfs bugfixes and cleanup. One major new feature here - hostfs
can now be the root filesystem. This is done by assigning a directory to a
ubd device, i.e. 'ubd0=/path/to/uml/root'. A little bit of magic will cause
this to be mounted as a hostfs filesystem. Requirements: hostfs compiled into
the kernel, /etc/fstab in that filesystem must have the / fs type as hostfs,
you (the user running UML) must own all the files (they will be magically
owned by root inside the virtual machine).

modify_ldt is now implemented.

/proc/cmdline is now right.

gdb automatically gets breakpoints set on panic and BUG.
