d19c17812c New debugger + inital PRAM/real-time clock + fixes
- Refactored VIA rega/b implementation
  - Timers don't "work" yet, but they work a little better
  - Split rega/b into input and output versions
  - Fixed a bug that would mistake VIA1 accesses for VIA2

- Added basic support for PRAM and the RTC, although they're not
  wired into the GUI yet

- Replaced every *alloc() call with an alloc_pool call, which is
  a start toward supporting clean restarts

- Replaced ea_addr, ea_read, ea_write, and ea_read_commit with
  jump tables

- Got rid of ~inst() macro in cpu.c

- added a GLUT-based debugger

9f0e6ed115 Speed improvements + little fixes + 0.0.2 release
- Converted condition-code + physical_get/set switch statements to jump tables
- Moved the pmmu_cache lookup code out of translate_logical_addr
- Broke MOVE into move-to-datareg, -from-datareg, and datareg-to-datareg
- Fixed UFS code to ignore high 32 bits of inode size (it sometimes contains garbage)
- Support for zero-length reads in scsi.c + 256kb read/write buffer
- pushing interrupt stack frames now actually changes the priority mask
- Updated the READMEs, screencaps for 0.0.2
