Debugger: Add IRQ support to LBR and new command to Break on Interrupt (#987, PR #990)
Extend LBR so that it includes the control-flow on a taken interrupt
Add a new command 'brkint <0|1>' to support Break on Interrupt

Internal: in core emulation loop, moved IRQ/NMI check to start of loop so that just the "interrupt vectoring" case can be single-stepped (instead of previously opcode + interrupt vector).

Debugger help chm: update Breakpoints section to include BRK, BRKOP and BRKINT

Improve SSI263 (PR #939)
New class for SSI263 (2 instances per MB/Phasor card)
- support 2nd SSI263 at $Cn20 connected to 6522-A (at $Cn00)

Switch from one-shot phoneme playback to ring-buffer
Use a new dedicated ring-buffer (distinct from the AY8910 ring buffer)
Gets rid of: SSI263Thread, the 2 events, and the 64 voices

Support the 2-bit Duration b7:6 of phoneme register for both SC01 & SSI263 (to fix #929)
Updated save-state
Updated IRQ logging (output cycle & 6522 source)

Source clean-up, portability and debugger fixes. (PR #842)
And fix two general issues:
- confusing behavior when entering the builtin (mini) assembler mode,
- and also fixes the "cl" (clear flag) command - which was documented, but did not work at all (due to an "interesting" command/syntax conflict...).

Support for synchronous events (PR #841)
Switched Mockingboard/6522 Timer interrupts & Mousecard's VBlank interrupt to use synchronous events.
This is a linked-list of ordered timer-based event, where only the head of the list needs updating after every opcode.

Removed 65d02 and used the regular 65c02/6502 headers instead (PR #825)
Removed 65d02.h and reconstructed this code using a combination of existing 6502.h/65c02.h and extra C Pre-Processor macros to include (or omit) the extra heatmap functionality.

We still end up with a normal 65c02 instance and also a debug 65c02 instance, but both will derive from the same 65c02.h file (+ same for the 6502 normal/debug instances).

Also:
. Added cpu_heatmap.inl for the built-in debugger's read/write operations.
. Support CpuRead/Write() from Z80 to hook the heatmap r/w.

Support 2nd Disk][ card and improved card management (#726) (PR #741)
Support 2nd Disk][ in slot-5, via command line:
- -s5 diskii
- -s5d1 \<imagefile\>
- -s5d2 \<imagefile\>

NB. there's currently no Configuration UI support, except the Drive icons' tooltips show what's in slot-5 & slot-6 (for drive-n). So there's no way to eject the disks or insert new disks. The use-case I'm supporting it Wasteland which just has the 4 disks in the 4 drives.

Improved card management:
- Added `class Card` (in Card.h) which all other cards (that exist as classes) derive from (eg. LC,SSC,Mouse,Disk2).
- Added `class CardManager` (in CardManager.cpp\h) which now manages the 8 slots (and aux slot).
- Added `class Disk2CardManager` (in Disk2CardManager.cpp\h) which provides methods for operations that act on all Disk2 instances at the same time.
- Currently limited to just 1x SSC and 1x Mouse card (why would you need more?). This simplifies things, meaning there's no need to have dedicated SSCManager / MouseCardManager objects.
- Currently the 2nd Disk2 card can only be put into slot-5. This limitation is just due to the complexity of the Configuration UI. Having a more general drop-down per slot UI would remove this limitation.

Fix for "Mad Effect 1&2" demos (PR #725)

8c019bcd35 More main-loop reduction & removal of redundant globals.
Fixed JoyUpdateButtonLatch() to debounce in 5mecs instead of 5secs!

SpkrToggle() was using redundant global ('cyclenum') when using the PC speaker.
. I reworked the code (as it looked out-of-date),
    but probably better to just remove all the PC speaker support.
