- 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.
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.

Tested on GhostBSD (based on FreeBSD)
It should work on DragonFlyBSD (the cpuctl driver has been ported from FreeBSD)
The situation for OpenBSD and NetBSD is not clear ; not supported
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`.
According to wikipedia, cpu-world and some cpu-z screenshots, these processors
do have a code name and it's willamette, northwood, prescott or cedar mill

The reason was that the invocation of the cpuid_tool through the makefile
was using LD_LIBRARY_PATH=. to force link&use of the latest-build libcpuid
library. This doesn't seem to work, so using LD_PRELOAD to explicitly load
libcpuid.so into cpuid_tool.
The committed approach of course doesn't work on Mac OS X, where
make test-old should be used.
msrdriver.c was forgotten from Makefile.am, under the assumption that
autotools are used under *nix only. This is not true, as one could use
MinGW or cygwin.
