remove m4 and autoconf stuff
remove more autoconf stuff
expr.y: don't fail if SDL is not defined
CheatSearch.h: fix build for C

this file is not built in the default config so its C++isms slipped through.
Cheats.c: dont fail to build without BKPT_SUPPORT
remote.c: dont fail to build without BKPT_SUPPORT
SDL.c: define SYSCONFDIR if not already set
SDL.c: remove platform-specific 'stretcher' jit code
remove bison/yacc generated files
TestEmu.c: remove useless include
remote.c: remove autotoolized conditional includes

these are the only headers that are conditionally included depending
on configure checks in the entire source tree, so we remove it for
consistency and just include them unconditionally.
this saves us from writing configure checks and implicit declaration
of inet_ntoa if the right HAVE_ define is not passed.
debugger.c: dont fail to build when BKPT_SUPPORT is not set
remove translation support
remove cvs related files
remove win32 files
move parser (lex/yaxx) input files to src/gen
memgzio.c/h: dont depend on files in win32 tree
parser files: fix relative paths
remove more unportable ASM, obsoleting C_CORE define

with C compilers getting better and better, there's hardly a reason
anymore to carry around decade old handwritten asm for a few selected
CPUs, plus the respective build system logic.
remove half-finished gtk port (requires C++)
