* Updated Doxygen documentation: added manpage output, generic mainpage intro, default module named correctly;
* Updated doxy libcpuid.h documentation, fixed some bugs;
* Warnings are now printed to stderr by default, not stdout;
* Some constants in AMD code did not reflected their meaning well, fixed;
* The cpuid_tool utility thoroughly redesigned; now a multiple-function program, perhaps close to the finalized state.
