Rewrote memory access handling to properly split execute from read, bus from CPU (but the mappings will still match until otherwise specified), and fixed exec[] usage by the mem_*_phys() functions.

Removed the redundant mem_write_null* functions (the few mappings that use them, now use NULL pointers instead) and made the _phys function used by DMA not write to the exec buffer if the address has no write mapping (as in that case, it's clearly not intended to be writable), fixes #1332 .

And of course, I forgot the modified include files in the previous commit.

Got rid of the last differences between the old and new recompilers with regards to the readmem*/writemem* functions.

Implemented PIC IRQ latch and delay (per the datasheet), IBM PCjr now works without a workaround delay in cpu/808x.c which was therefore removed; also redid memory and I/O accesses in cpu/808x.c to fix word writes on 8086.

PIC rewrite, proper SMRAM API, complete SiS 471 rewrite and addition of 40x, 460, and 461, changes to mem.c/h, disabled Voodoo memory dumping on exit, bumped SDL Hardware scale quality to 2, bumped IDE/ATAPI drives to ATA-6, finally bumped emulator version to 3.0, redid the bus type ID's to allow for planned ATAPI hard disks, made SST flash set its high mappings to the correct address if the CPU is 16-bit, and added the SiS 401 AMI 486 Clone, AOpen Vi15G, and the Soyo 4SA2 (486 with SiS 496/497 that can boot from CD-ROM), assorted 286+ protected mode fixes (for slightly more accuracy), and fixes to 808x emulation (MS Word 1.0 and 1.10 for DOS now work correctly from floppy).

Overhauled the SiS 496/497 chipset emulation (and added the DRB locking to it) (later Zida Tomato 4DPS BIOS'es now work, and we now use the actual 1.72), fixed the W83787F and FDC37C932FR Super I/O chips, removed the no longer needed Acer M3A registers (that's now correctly handled as FDC37C932FR GPIO), and a number of bugfixes here and there.

Some chipset extended SMRAM-related clean-ups and SMM-supporting chipsets now correctly set shadow RAM states for SMM mode in addition to non-SMM mode, fixes Windows 98 SE hanging in a SMI# handler.

Implemented the Intel 420EX combined northbridge and southbridge, added the ASUS PVI-486AP4, and overhauled SMRAM handling (which also implements some previously missing extended SMRAM features of the 440BX+ and VIA Apollo series of chipsets).

Applied Ryuzaki's Media menu patch, fixed a bug in cpu.c reported by ms. person, fixed bugs (and added a workaround for the Windows 2000 PCnet problems) to mem.c, and added a network packet queue to cap network speed (and do the actual rx poll in the main thread instead) for more stability, also some ES1371 fixes (but not enough to make it work on Linux).

Move all include files to src/include
...
- 86Box's own headers go to /86box
- munt's public interface goes to /mt32emu
- all slirp headers go to /slirp (might want to consider using only its public inteface)
- single file headers from other projects go in include root
