c31b5c0ae8 Add up to 8 entries for CPUID leaf 04; push version to 0.3.0. 
This is a backwards-incompatible binary change, which increases
sizeof(cpu_raw_data_t). Specifically, the cpu_raw_data_t::intel_fn4
array is increased from 4 to 8 elements, because on recent Hasells
(Crystalwell) there is a Level 4 cache, which should be encoded in
CPUID eax=4 ecx=4. However, we were only storing levels for eax=4
for ecx <= 3. Thus the raw data didn't have the relevant info.

There will be further changes to this, specifically to store
and print the level 4 cache in cpuid_tool.

a2550463a9 Reorganize library a bit. 
- 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.

8c629d76b4 Fix minor issues with comments/documentation. 
Also add a comment about the upcoming version 0.2.3. A date is not
stated, as this will be done when the actual release happens (and
I will collect any further patches up to that moment). I expect the
release to be over the next weekend.

1073370613 Related to pull request #35: Expose intel brand & model codes. 
The detected intel brand code and model code (arbitrary numbers,
related to the detection algorithm) are printed at verbosiness level
2 or higher. You can see them with `cpuid_tool --all -vv` (if running
on an Intel CPU), or, generally, when decoding Intel CPU data, e.g.
`cpuid_tool --load=tests/intel/nehalem/bloomfield.test --all -vv`.
