Adding some missing command definitions and update the existing ones.
No functional change.
Add: LOCATE_10, UNMAP, VARLENGTH_CDB, WRITE_FILEMARKS_16, EXTENDED_COPY,
ATA_PASSTHROUGH, ACCESS_CONTROL_IN, ACCESS_CONTROL_OUT,
COMPARE_AND_WRITE, VERIFY_16, SYNCHRONIZE_CACHE_16, LOCATE_16, ERASE_16,
WRITE_LONG_16, VERIFY_12, READ_DEFECT_DATA_12.
Rename: READ_CAPACITY, WRITE_VERIFY, VERIFY, READ_LONG, WRITE_LONG,
WRITE_SAME to&_10.
Delete: WRITE_LONG_2
OK.

Intentionally. VARLENGHT_CDB is used for all sorts of things, so
