all cpu-related stuff is now defined in cpu.h (with cpu_ prefix and fully encapsulated). fix quite brittle core/HT unit/package detection. implement mkdir on VC8, where it is deprecated add strdup on MacOSX move ia32 code into separate subdir. functions implemented in asm are called ia32_asm_*. add some unix versions of sysdep functions (cannot test them) timer: fix for amd64 linux This was SVN commit r4995.
