Better support the IIe's aux slot when it's empty or has the 80-col(1KiB) card.
- any h/w using this alternate CPU emulation, (ie. aux=empty or 80-col(1KiB)), then the 'mem' cache is completely bypassed.
Debugger: change all the direct 'mem' accesses to go via ReadByteFromMemory().
TestCPU6502: test the alt CPU emulation code too.
- Improve FormatCharCopy() to not buffer overflow
- Improve FormatOpcodeBytes() to not buffer overflow
- Improve FormatNopcodeBytes() to not buffer overflow
- Change FormatDisassemblyLine() to return std::string
And these Debugger related:
. Improve FormatAddress() and GetSymbol().
. GetSymbol(), FindSymbolFromAddress(), FormatAddress() are changed to use std::string instead.
. Remove static variable (not nice) in FormatAddress().
. GetSymbol() returns std::string reference instead of pointer.
- Update LogOutput() and LogFileOutput().
- Add StrFormat() to produce std::string out of snprintf() & add StrFormat.cpp to projects.
- Add PTRDIFF_T_FMT in parallel to SIZE_T_FMT to StdAfx.h, for completeness.
- In Log.cpp, changed to get timestamp using posix functions.
- Removed TCHAR usage throughout - simply use char.
