13a4043118 Added a new PerfMarker class: used to instrument emulation sub-systems and log timings (#788)
To enable this uncomment the #define LOG_PERF_TIMINGS in AppleWin.h.

9f49820a8d Phasor: support SSI263 speech for Mockingboard mode (#777)
. Improved DEVICE_SELECT' I/O support (including Echo+).
. SSI263_Read() only for Phasor in Phasor mode.
. save-state: v6 (Phasor unit): phasor mode extended.
SSI263 (MB/Phasor) bug fix for when RESET/Power-cycle during phoneme playback.
Logging:
. improved for SSI263
. in CPU.cpp, added 'IRQ' / 'ISR-end'

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)
. 6502 interrupt delays 1 opcode when interrupt occurs on last cycle of opcode (#724).
. Only 1-cycle delay for VF_TEXT & VF_MIXED mode changes (#656).
NB. Mad Effect 1 still has a bit of flicker on Space Invader (left edge)

d9a15c30da Save-state: fix for loading state not re-asserting pending IRQs for Mouse & SSC. (#677)

Changes to ease code compilation in GCC.

Disk_t and HDD contain a std::string and for this reason they need a proper constructor, ZeroMemory is not guaranteed to work.

3d6c10bad9 Debugger:
. Move the BRK and invalid opcodes checks out of main emulation's Fetch() and into DebugContinueStepping()
. Added a new break condition: when PC reads floating bus or I/O memory
. On a break condition, output a 'Stop Reason' message to the console

0b6c5bbb91 Support for #384:
. Debug 'G(o)' cmd now defaults to normal speed (and precise video updates)
. New debug 'GG' cmd enables full speed (and periodic video updates)
. Single-stepping (normal or full speed) now routed through ContinueExecution()
. Removed Cpu6502()/Cpu65C02() check for debug breakpoints
. Removed the (undocumented) SHIFT+F7 feature to exit debugger for 'normal speed breakpoints'
. Removed the g_bDebugNormalSpeedBreakpoints variable

8447a22942 VBlank tweaks:
. Removed NTSC_VideoVbl(), since it's not accurate during full-speed. (Nothing was using it)
. Renamed VideoGetVbl() to VideoGetVblBar()
. Correctly pass Vbl (not VblBar) to Mouse's SetVBlank()

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.
