remove mmgr and macros that redefine malloc/new/free

(see http://www.wildfiregames.com/forum/index.php?showtopic=11450&hl= )

clean up debug module
. no longer include platform-dependent header (-> less rebuilds)
. DISPLAY_ERROR -> DEBUG_DISPLAY_ERROR
. parts of config.h that don't affect all files moved to config.2 (->
fewer full rebuilds)
. remove creaky symbol cache (no longer needed for mmgr)
. remove TLS thread naming stuff (can use debugger's thread window
instead; no need for platform independence there)

wdbg: remove thread suspension and breakpoint APIs (not needed)

acpi: fix: u64 -> uintptr_t

wutil: fix WinScopedLock, use that instead of direct lock() functions

misc:
. get rid of SAFE_STRCPY, replace with strcpy_s
. remove _getcwd (shouldn't be used)

This was SVN commit r5563.
