sg: improve sg_write_mode option names

There is a name collision for the sg_write_mode options for the WRITE AND
VERIFY and VERIFY commands. Deprecate the 'verify' option and use
'write_and_verify' instead. Do the same thing for 'same' and 'write_same' to
have a consistent naming scheme. The original option names are still supported
for backward compatibility but list them as deprecated.

Here are the new sg_write_mode options:

Option			SCSI command
write			WRITE (default)
write_and_verify	WRITE AND VERIFY
verify (deprecated)	WRITE AND VERIFY
write_same		WRITE SAME
same (deprecated)	WRITE SAME
write_same_ndob         WRITE SAME with NDOB flag set
verify_bytchk_00	VERIFY with BYTCHK set to 00
verify_bytchk_01	VERIFY with BYTCHK set to 01
verify_bytchk_11	VERIFY with BYTCHK set to 11
