- Expose intel_code_t and amd_code_t enums - they are no longer
limited to just recog_{intel,amd}.c.
- Add libcpuid_internal.h lists those enums and provides the,
cpu_ident_internal() function, which is the same as cpu_identify(),
but also has a third parameter - a internal_id_info_t structure,
which holds detection internals.
All of this is intended to be used in rdmsr, which needs to know
specifics on what CPU it is running.
