12b53038f6 bdev/aio: Poller handles inline channel deletion
Change the poller to tolerate channel deletion within
an I/O completion callback. This won't happen today
because channel deletion is always deferred, but
prepare for that case.

It turns out this is simpler anyway.

f71447e80d bdev: remove differentiation between bdev and vbdev modules
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.

7fefd60fab bdev: make module init synchronous again
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.

dd06e98d4a bdev: rename blockdev instances to bdev
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.
