libqos/ahci: add ahci command functions
This patch adds the AHCICommand structure, and a set of functions to operate on the structure. ahci_command_create - Initialize and create a new AHCICommand in memory ahci_command_free - Destroy this object. ahci_command_set_buffer - Set where the guest memory DMA buffer is. ahci_command_commit - Write this command to the AHCI HBA. ahci_command_issue - Issue the committed command synchronously. ahci_command_issue_async - Issue the committed command asynchronously. ahci_command_wait - Wait for an asynchronous command to finish. ahci_command_slot - Get the number of the command slot we committed to. Helpers: size_to_prdtl - Calculate the required minimum PRDTL size from a buffer size. ahci_command_find - Given an ATA command mnemonic, look it up in the properties table to obtain info about the command. command_header_init - Initialize the command header with sane values. command_table_init - Initialize the command table with sane values.
