behlendo e966e04fd5 Ensure all file ops pointer are NULL or we may end up
calling garbage pointers on open/close etc and get
what look like random crashes.

behlendo 8d0f1ee907 Add some crude debugging support. It leaves alot to be
desired, but it should allow more easy kernel debugging for now.

behlendo 9f4c835a0e Correctly functioning 64-bit atomic shim layer. It's not
what I would call effecient but it does have the advantage
of being correct which is all I need right now.  I added
a regression test as well.

behlendo 4e62fd4104 OK, a first reasonable attempt at a solaris module/chdev shim layer.
This should handle the absolute minimum I need for ZFS.  It will 
register the chdev with the right callbacks.  Then the generic 
registered linux callback will find the right registered solaris
callback for the function and munge the args just right before
passing it on.  Should work, but untested (just compiled), so I
expect bugs.

behlendo e4f1d29f89 OK, some pretty substantial rework here. I've merged the spl-file
stuff which only inclused the getf()/releasef() in to the vnode area
where it will only really be used.  These calls allow a user to
grab an open file struct given only the known open fd for a particular
user context.  ZFS makes use of these, but they're a bit tricky to
test from within the kernel since you already need the file open
and know the fd.  So we basically spook the system calls to setup
the environment we need for the splat test case and verify given
just the know fd we can get the file, create the needed vnode, and
then use the vnode interface as usual to read and write from it.

While I was hacking away I also noticed a NULL termination issue
in the second kobj test case so I fixed that too.  In fact, I fixed
a few other things as well but all for the best!

behlendo 9490c14835 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

behlendo 596e65b4e8 OK, I think this is the last of major cleanup and restructuring.
We've dropped all the linux- prefixes on the file in favor of spl-
which makes more sense.  And we've cleaned up some of the includes
so everybody should be including their own dependencies properly.
All a module which wants to use the spl support needs to do in
include spl.h and ensure it has access to Module.symvers.

behlendo a0aadf5666 OK, everything builds now. My initial intent was to place all of
the directories at the top level but that proved troublesome.  The
kernel buildsystem and autoconf were conflicting too much.  To 
resolve the issue I moved the kernel bits in to a modules directory
which can then only use the kernel build system.  We just pass 
along the likely make targets to the kernel build system.
