Eric Blake 4c41cb4955 block: Update comments on BDRV_BLOCK_* meanings 
We had some conflicting documentation: a nice 8-way table that
described all possible combinations of DATA, ZERO, and
OFFSET_VALID, contrasted with text that implied that OFFSET_VALID
always meant raw data could be read directly.  Furthermore, the
text refers a lot to bs->file, even though the interface was
updated back in 67a0fd2a to let the driver pass back a specific
BDS (not necessarily bs->file).  As the 8-way table is the
intended semantics, simplify the rest of the text to get rid of
the confusion.

ALLOCATED is always set by the block layer for convenience (drivers
do not have to worry about it).  RAW is used only internally, but
by more than the raw driver.  Document these additional items on
the driver callback.
