We should not include glibc headers from BIOS code which can't rely on glibc at
runtime.

This patch fixes the following build breakage on 64-bit:

  make: *** [bios/bios.bin.elf] Error 1

when built without the 'glibc-devel.i686' package on Fedora, for example.

This patch makes debug output go to a 'debug_fd' instead of stdout.

Doing so allows us to send the output to a different console when
required.

This patch also changes the behaviour of 'kvm debug' to show the debug
output in the console that executed the debug command instead of in the
console of the guest.

Add some missing keys to the SDL ui. This needed a bit of rework of
keyboard event handling since some of the new codes are multi-byte,
so I had to introduce a struct that keeps that information alongside
the code itself. Peculiar cases like PAUSE or PRNT SCRN are special
cased, however they aren't wired yet since I couldn't test them (I think
input grabbing is required to make them work).

This patch adds the '-tty' option to 'kvm run' which allows the user to
remap a guest TTY into a PTS on the host.

Usage:
        'kvm run --tty [id]'

The tty will be mapped to a pts and will be printed on the screen:
        '  Info: Assigned terminal 1 to pty /dev/pts/X'

At this point, it is possible to communicate with the guest using that pty.

This is useful for debugging guest kernel using KGDB:

1. Run the guest:
        'kvm run -k [vmlinuz] -p "kgdboc=ttyS1 kgdbwait" --tty 1'

And see which PTY got assigned to ttyS1.

2. Run GDB on the host:
        'gdb [vmlinuz]'

3. Connect to the guest (from within GDB):
        'target remote /dev/pty/X'

4. Start debugging! (enter 'continue' to continue boot).

This patch removes the manual/usermode dhcp client configuration and instead
uses the DHCP client built within the kernel.

Since this client is tightly integrated with NFS (if NFS config is set), we
will add a specific NFS root addr in our DHCP offer to point it to a non
existent address so that we won't hang trying to poke it for our root.
