Update to SeaBIOS 0.5.0

The only change is updating the makefile but that way we're carrying an official
release.

Fix thinko in linuxboot.S

The %gs segment that was used was not matching the comments.
I just moved the GDT descriptor on the stack instead.

Make -kernel for linux work with bochsbios

While trying to run -kernel with -bios pc-bios/pcbios.bin, I realized
that I was actually writing data to %es, but only set up %ds to a 32-bit
segment we want to write to.

So at the end of the day the data hasn't actually been copied. Oops....

Allow build of linuxboot.S with old assemblers

In the spirit of ff56954baf9cfab5cbbe18d10b4a09e4a17f39a8, fix the
build of linuxboot.S with old as(1) (as found in some BSD base systems)
by emitting the bytes of the insn it doesn't like instead.

Move common option rom code to header file

We will have a linux boot option rom soon, so let's take all functionality
that might be useful for both to a header file that both roms can include.

That way we only have to write fw_cfg access code once.

Convert linux bootrom to external rom and fw_cfg

We already have a working multiboot implementation that uses fw_cfg to get
its kernel module etc. data in int19 runtime now.

So what's missing is a working linux boot option rom. While at it I figured it
would be a good idea to take the opcode generator out of pc.c and instead use...
