ddb enhancements

[Frank Wille <frank%phoenix.owl.de@localhost>]

Hi,

I was working on ddb for PPC the last two days and mainly did a lot of bug
fixes and enhancements to the disassembler.

But also the machine directive got two new sub commands: bat (show all BAT
registers with detailed information) and mmu (show sdr1, asr, sr
registers).

The new commands should probably also be mentioned on the man-page, but
where do I find the ddb man page source?
