Commit 721fdf34167580ff98263c74cead8871d76936e6 introduced a subtle bug
by accidently removing the "static" from iodc_dbuf. This resulted in, what
appeared to be, a trap without *current set to a task. Probably the result of
a trap in real mode while calling firmware.
Also do other misc clean ups. Since the only input from firmware is non
blocking, share iodc_dbuf between input and output, and spinlock the
only callers.

There's really no reason not to print more than one character at a
time to the PDC console... Booting is measurably speedier, and now I don't
have to watch individual characters get drawn.

MAX_NR_CONSOLES, fg_console, want_console and last_console are more of a
function of the VT layer than the TTY one. Moving these to vt.h and vt_kern.h
allows all of the framebuffer and VT console drivers to remove their
dependency on tty.h.

Get rid of some unnecessary includes
Remove a layer of macro indirection around pdc_console_device
Delete pdc_console_die() as it is unused
Avoid double-printing on panic by clearing CON_PRINTBUFFER rather than
setting con_start to be log_end
Make con_start and log_end static again

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
