biosemu (non-yabel) cleanup
* Drop pcbios folder that only exists for a single function * include int1a handler in biosemu.c * Wipe a lot of dead code, and set up F segment correctly * include return value check from yabel. On the long run we should teach yabel to be able to run with a reduced feature set, ie. no emulation of (almost) all system hardware. Then we could drop the non-yabel x86emu. But for now this patch cleans up the non-yabel biosemu.c to a state where it's not all that ugly anymore..
