ia32: prepend CPUCap enum names and rdtsc with ia32 to avoid conflicts. move all self tests into separate headers as required for Cxxtest. adts: remove some dead code. add CppDoc comments to debug, lib (with heavy cleanup), tex, tex_codec, snd_mgr slight improvements to path tex: refactor; split out tex_decode and encode to allow self-test This was SVN commit r3911.
