2015-02-16libqos/ahci: create libqos/ahci.cJohn Snow2-1/+279
With global state removed, code responsible for booting up, verifying, and initializing the AHCI HBA is extracted and inserted into libqos/ahci.c, which would allow for other qtests in the future to quickly grab a meaningfully initialized reference to an AHCI HBA. Even without other users, functionalizing and isolating the code assists future AHCI tests that exercise Q35 migration. For now, libqos/ahci.o will be PC-only, but can be expanded into something arch-agnostic in the future, if needed.
