VMWare backdoor interface should work with IN/OUT port ops, but
currently only IN is supported. BOCHS bios uses OUT to query UUID.
The patch adds OUT support.

This patch moves the pty char device imlementation away from the generic
filehandle code. It tries to detect as good as possible whenever there
is someone connected to the slave pty device and only send data down the
road in case someone is listening. Unfortunaly we have to poll via
timer once in a while to check the status because we have to use read()
on the master pty to figure the status (returns -EIO when unconnected).
Poll intervall for an idle guest is one second, when the guest sends
data to the virtual device linked to the pty we check more frequently.
The point for all of this is to avoid qemu blocking and not responding
any more. Writing to the master pty handle succeeds even when nobody is
connected to (and reading from) to the slave end of the pty. The kernel
just bufferes the writes. And as soon as the kernel buffer is full the
write() call blocks forever ...

That should teach one to not blindly trust documentation that will
(out of the blue) use decimal and binary representation for numbers in
the same chart for no apparent reason and without any prefixes, sigh..
Unbreaks MIPS.

VDE isn't used unless the user explicitly asks for it so if the library is
present on the system, we should include support for it.

When using -daemonize, we want to avoid chdir() until after we've opened the
block devices. It's also perfectly fine to use -dameonize along with SDL.
