Remove trailing whitespace.

"smart status" already obtains the ata parameters to check if smart
is actually supported, so we can attempt to guess a vendor smart
table from the model name. add basic support for all the micron /
crucial disk names i could find, and add a couple more micron
specific values.

XXX: probably should add regex support for matching, and probably
should be more restrictive with the current matches.

Use more appropriate macros. Make a sentence easier to read.

extend "smart status" command to "smart status [vendor]", and supply a
"Micron" (for Micron/Crucial) list with their documented values.

this allows the vendor-specific data to be used.

there appears to be no simple way to automatically determine the right
vendor to use -- identify data seems to be the only obvious way and
that data can be and is changed by OEMs. (eg, a disk may be listed as
being "dell", but dell don't make disks.) as such, no attempt is made
to automatically determine if a vendor list should be used.

add SMART code 187: "Reported uncorrect". from smartmontools.

Add display of Long Physical Sector and Long Logical Sectors feature set
information to atactl identify output.

Also:
- remove caddr_t cast
- warn about invalid IDENTIFY data checksum (when possible)
- humanize capacity in power-of-10 format
- remove semi-pointless ATAPI check
- slightly rework command queue depth output to be less conversational

Improve "identify" output slightly:
- Capitialize "Name" in World Wide Name.
- Print the World Wide Name if it exists.
- Use LBA48 maximum address when available for "total sectors" output.
- So that geometry will display on more drives, don't be as strict when
checking for non-ATAPI devices. (This seemed to be an issue on at least
one instance of a Caviar SE16 drive.)
- Check more carefully for valid/relevant queue depth before printing it.
- Increment the queue depth by one for display.

While here, wrap some long lines that I should have had wrapped before they
were commited in rev. 1.46.

Move WARNS=3 to the Makefile.inc, and add a little const to the remaining
programs that did not compile before.

Implement a "security" command with subcommands to query the status of
the "security" extension and to "freeze" it. With the security extension
frozen, disk passwords cannot be set anymore, until the next hard reset.
Normally, this is the business of the BIOS, but older/buggy/embedded
BIOSes don't care. This leaves the (theoretical) possibility that a
malicious program in posession of superuser rights sets a disk password,
rendering the disk useless (or at least uneconomical to recover from).
Inspired by an article in the german "ct" magazine.
Being here, consolidate the implementations of IDENTIFY into one, and

there are names for some of the one that were missing them.
