Split the 286/386 interpreter away from the 486+ one (the 286/386 interpreter does not use the pccache's, readlookup's, and writelookup's as the emulated CPU's are too slow for them to be required, and also has more accurate FPU timings), also added a LPT status read function for future-proofing.

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.
