2016-01-11libqos/ahci: add ahci_execJohn Snow
add ahci_exec, which is a standard purpose flexible command dispatcher and tester for the AHCI device.

2016-01-11libqos: allow zero-size allocationsJohn Snow
As part of streamlining the AHCI tests interface, it'd be nice if specying a size of zero could be handled without special branches and the allocator could handle this special case gracefully. This lets me use the "ahci_io" macros for non-data commands, too, which moves me forward towards shepherding all AHCI qtests into a common set of commands in a unified pipeline.

2016-01-11libqos/ahci: Switch to mutable propertiesJohn Snow
ATAPI commands are, unfortunately, weird in that they can be either DMA or PIO depending on a header bit. In order to accommodate them, I'll need to make AHCI command properties mutable so we can toggle between which "flavor" of ATAPI command we want to test. The default ATAPI transfer mechanism is PIO and the default properties are adjusted accordingly.

2016-01-11libqos/ahci: ATAPI supportJohn Snow
Add pathways to tolerate ATAPI commands. Notably, unlike ATA, each SCSI command's layout is a little different, so support will have to be patched in for each command as we want to test them in e.g. ahci_command_set_sizes and ahci_command_set_offset. For now, I'm adding support for 0x28, READ (10).
