someone sees an easy way to make DECLARE_STUB handle this case
that'd be cleaner but I don't think its a big deal) and (2)
updated DECLARE_STUB so that it can set a struct return value
by adding {} to the ut_ variable set statement.
Also ordered the declarations simply for readability, the _V
first, the regular stubs next, the _P next and then the stubs
that don't have a macro to cover them because they do something

This variable was misleading and unnecessary. Replaced all it's
occurences with SPDK_SCSI_DEV_MAX_LUN.

Add a new spdk_vbdev_module_examine_done() API which
vbdev modules can use to notify the generic bdev layer
once a base bdev examination is complete.
This is especially required for asynchronous vbdevs
like GPT which must issue I/O to the base bdev.
As part of this patch, add examine callbacks
for both split and error, which for now only call
this new functions. Later patches will move code from
the init callback to the examine callback for these
modules. examine callbacks are now required for all
vbdev modules.

This is a bit of a workaround for some upcoming changes
where bdev subsystem initialization will not wait for
all vbdevs to finish tasting all bdevs that are registered.
We need to allow those vbdevs to clean up after themselves
after doing their initial tasting, before we start the
unit tests, since the unit tests are blocking and won't
return to the reactor loop to allow asynchronous tasting
I/O to get returned to the vbdev modules.
Eventually we should consider modifying bdevio run
asynchronously, maybe including removing its use of CUnit
for test reporting.
