bdev: Create a separate bdev subsystem library

Much like bdev modules inside the bdev directory,
add a subsystems directory inside of event. The subsystem
specific code for the bdev library is placed in to
a separate library in that directory, breaking the
strict dependency of the bdev library on the event subsystem
code.
