This removes the old i386 setup code. This is done as a separate patch
to avoid breaking git bisect as some of the i386 code was also used by
the old x86-64 code.

Video mode probing for the new x86 setup code. This code breaks down
different drivers into modules. This code deliberately drops support
for a lot of the vendor-specific mode probing present in the assembly
version, since a lot of those probes have been found to be stale in
current versions of those chips -- frequently, support for those modes
have been dropped from recent video BIOSes due to space constraints,
but the video BIOS signatures are still the same.
However, additional drivers should be extremely straightforward to plug
in, if desirable.

To support multiple TC microthreads acting as "CPUs" within a VPE,
VPE-wide interrupt mask bits must be specially manipulated during
interrupt handling. To support legacy drivers and interrupt controller
management code, SMTC has a "backstop" to track and if necessary restore
the interrupt mask. This has some performance impact on interrupt service
overhead. Disable it only if you know what you are doing.
