6051bc55d0 Changes to ease code compilation in gcc. (#541)
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

04c9d09e38 When FullSpeed: don't do cycle-accurate graphics update
. means that disk accesses (eg. loading) is much quicker
Correct naming of video modes (in UI and code)
Pixel adjust for NTSC B&W and Color video modes to align with other video modes
