Minor SwEng improvements

[Jan Wassenberg]

Some possibilities for minor improvement noticed while cruising by:

• premake: document extra_params
• ogl: remove EXT_ symbols, use glext instead
• debug_stl: prefix symbols with debug_stl
• adts: move cache into separate file (also remove old cache impl)
• wgl: prevent multiple include
• move SDL files in sysdep/win to libraries/SDL
• delay_load uses NLSO ctor to register functions. require load_notify to be called at init time. (rationale: this no longer works since splitting up into several static libs)
• wsock_init: call via module init, have it do load_notify call
• ScopeTimerAccrue: change #ifdef spaghetti into templated policy class
• app_hooks, define VOID_FUNC to FUNC(.., (void) )
• look at stalk walk code; any reason not to work on Win64?
• replace ERR_TEX_CODEC_CANNOT_HANDLE with INFO_* - not an error. also ERR_SYM_SUPPRESS_OUTPUT ERR_SYM_SINGLE_SYMBOL_LIMIT
• wdbg_sym: only import RtlCaptureContext once (not every walk_stack)
• add sys_last_error (GetLastError on win32); converts to text in display_error, also show sys_last_error and errno
• app_hooks: move i18n impl out (belongs in pyrogenesis)
• move non-lib asm code into separate asm file; split out memcpy and color code from ia32_asm.asm
• rename all C headers to C++ name (e.g. cmath) Deemed not worth the effort.
• fix mem leaks No longer happens.
• move GUIbase.h errors (DECLARE_ERROR) into philip's error mechanism, remove DECLARE_ERROR, remove ps/errors.h Separate ticket.

(In [4039]) # improvements to build system for asm files split ia32_asm code up into memcpy, color premake: add (windows-only so far) support for NASM include paths - required when using %include. see rationale in vs.c refs #124
