instead. We do not make use of the PMI and RELADDR bits in the
READ CAPACITY command, and thus there is no difference between
cd and sd capacity handling. Brings cd and sd more into line,
shrinks code and makes things easier to understand.
Make types for blocksize and disksize consistant and MI.
Make cdopen() as silent as sdopen().

identical to their counterparts.

RAW_PART will always be 0 -> disksize, so the bounds check will always
pass for i/o's to valid addresses. Now the i/o will be properly truncated
if it goes past the end of the device. This prevents various adverse
impacts of issuing i/o's for data past the end of the device.

1) remove multiple size queues, introduced as a stopgap.
2) decouple pages containing data from their mappings
3) only keep buffers mapped when they actually have to be mapped
(right now, this is when buffers are B_BUSY)
4) New functions to make a buffer busy, and release the busy flag
(buf_acquire and buf_release)
5) Move high/low water marks and statistics counters into a structure
6) Add a sysctl to retrieve buffer cache statistics

"becoming ready" - this is done in the exact same way that it
was done for tape in st.c. This commit adds a cd specific interpret_sense
routine to cd.c that will catch the becoming ready case and handle it.
This also removes the need to use crazy timeouts to catch this case.

floppies and cd's were removable, displaying that fact in disklabel
output was unlikely to help. And the display in disklabel was the only
use of D_REMOVABLE in the tree.

that specifies the version of SCSI being supported. Even the ANSI part
that we use is complex. 4 means 2, 5 means 3 and 6 means 4. Translate
and use the value correctly. Fixes SCSI5 and SCSI6 in dmesg. And
properly protects SCSI2 devices from getting SCSI3 commands.

information in the TOC. The partition info is just overwritten or
rendered incomplete by readdisklabel().
Just examine the TOC to determine if the cd is audio only, i.e. it has
a valid TOC but no data tracks. In this case don't call
readdisklabel(). Much simpler code. No functional change for single
data track CD's like the install media.

1) Using cd_load_toc() instead of replicating code.
2) Using struct cd_toc and betoh32() like other parts of cd.c.
3) Restoring pre-Sept. 26 behaviour of trying to read usable disklabel
info if there is no TOC. i.e. avoid readdisklabel() only when it is an
audio-only CD. Stop abusing spoofonly.
