1) Ensure mutex_init() never fails in the case of ENOMEM by retrying
forever. I don't think I've ever seen this happen but it was clear
after code inspection that if it did we would immediately crash.
2) Enable full debugging in check.sh for sanity tests. Might as well
get as much debug as we can in the case of a failure.
3) Reworked list of kmem caches tracked by SPL in to a hash with the
key based on the address of the kmem_cache_t. This should speed
up the constructor/destructor/shrinker lookup needed now for newer
kernel which removed the destructor support.
4) Updated kmem_cache_create to handle the case where CONFIG_SLUB
is defined. The slub would occasionally merge slab caches which
resulted in non-unique keys for our hash lookup in 3). To fix this
we detect if the slub is enabled and then set the needed flag
to prevent this merging from ever occuring.
5) New kernels removed the proc_dir_entry pointer from items
registered by sysctl. This means we can no long be sneaky and
manually insert things in to the sysctl tree simply by walking
the proc tree. So I'm forced to create a seperate tree for
all the things I can't easily support via sysctl interface.
I don't like it but it will do for now.

- Re-implmented kobj support based on the vnode support.
- Add TESTS option to check.sh, and removed delay after module load.

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

suite. Careful with this right now one of the tests still
causes a lockup on the node. This happened before the move
from the ZFS repo so its not a new issue.
