37f9e627ba Change from last_opcode/last_operand to opcode/operand
This change also makes it so that those values are set once they are
known, rather than only at the end of the execute function.

8e810e724f Add addr_mode field, rely upon it vs. the opcode
This makes testing _slightly_ easier, because now the handlers require a
type of state in the cpu vs. a specific opcode state in the segment that
we execute from. (The latter being just more complex to work with and
require in testing.)

This change simply replicates the behavior demonstrated in AppleWin.

6e77e99813 Add ability to debug separate from pausing
Also, pausing just pauses now; no debugger prompt is shown. ALT+P
toggles pausing, so just hit it again to unpause. Also, when things are
paused, you can perform other keyboard events (like quitting).

f9d130ba97 Add an extremely crude method to slow things down
It's not configurable, and not accurate to any particular measure. But
it's something for now.

281544bf43 Avoid polling for events until we're ready for a frame redraw
This change drastically cuts the number of times we poll for events, and
consequently drastically speeds up the number of frames we can draw
within any given span of time.

In other words, we go from "this barely moves as fast as the actual
Apple II" to "holy shit this moves so fast".

c178e417b7 Separate window and renderer creation; use software rendering
It seems _slightly_ faster than hardware acceleration for the uses we
have.

221d798c82 Remove online checks
That doesn't seem to be how the motor on/off status works. This
basically stops the motor from actively spinning, but it does not
prevent the drive from basic operation.

Peter Evans
0ccabda71e Rewrite SBC logic
The carry handling was incorrect; carry is set if we went below zero,
but bit 7 is not enough to determine that. It follows that negative
handling needed to be modified accordingly. Overflow handling was also
incorrect.

523b9c4a03 Several changes...
1. We have much more logging.
2. We were not properly turning off drives when we would get called with
   C0x8.
3. We now roll over sector pos if we are greater than ENC_ETRACK.
4. We now reset sector pos when we step.

d2047457e9 Use log_crit() instead of log_critical()
This change also removes the former log_critical and log_error macros.
