The bdev modules now take all read, write, unmap, and flush requests in
terms of blocks rather than bytes.
The public bdev APIs still accept offset and length in bytes for now.

This is far simpler, although it does limit the bdev
layer to unmapped just one range per command. In practice,
all of our code reports limits of just one range per command
anyway.

We still will sort the bdev_module list so that modules
with an examine() callback are initialized first. This ensures
they have a chance to initialize before later modules start
registering physical block devices.

Module initializaiton was made asynchronous recently
to support bdev modules like gpt which need to do
asynchronous I/O. But all modules now do any
asynchronous I/O in their examine() routines, and
init functions only do very basic operations to be
ready to handle examine() callbacks.
So simplify the bdev code and modules to go back to
a synchronous init procedure.

This includes file names, functions, #defines, etc.
There are still a few uses of "blockdev" outside of
include/ and lib/ - these can be handled later.
This preps for a future patch to consolidate vbdev
modules and bdev modules into just bdev modules.
