- cpu_thread now stops and waits on a pthread condition variable, rather
than sleep(1)ing and waiting to be pthread_kill()'d. Signals don't
work well on Windows, apparently.
- fopen() now open binary files with the "b" mode
- the keymap red-black tree no longer casts pointers to ints, because
mingw/gcc complains about it
- added a dumb batch script to compile the sdl gui on windows
- {n,h}to{h,n}{s,l,ll} is now handled better on windows
- sdl-gui/sdl.c is a tiny, basically working SDL2-based GUI that can compile and run on linux.
It still needs PRAM integration and a config file.
- Fixed a dumb bug in shoebill_initialize that was causing sporadic crashes
- Replaced a million printf() calls with slog(), to make the SDL client run more quietly on the CLI
- Added more corruption checking to alloc_pool
Restart/shutdown now work (most of the time)
PRAM is now integrated into the GUI
The real time clock sorta works, but is a bit wonky
Full-screen support
Lots of other little bug 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
