Apply fix from bug239 for rwlock deadlock.

Update check.sh script to take V=1 env var so you can run it verbosely as
follows if your chasing something: sudo make check V=1

Add new kobj api and needed regression tests to allow reading of files from
within the kernel.  Normally thats not something I support but the spa layer
needs the support for its config file.

Add some more missing stub headers
