behlendo 9ab1ac14ad Commit adaptive mutexes. This seems to have introduced some new
crashes but it's not clear to me yet if these are a problem with
the mutex implementation or ZFSs usage of it.

Minor taskq fixes to add new tasks to the end of the pending list.

Minor enhansements to the debug infrastructure.

* include/sys/mutex.h : Implemented a close approximation
of adaptive mutexes. These changes however required me to
export a new symbol from the kernel proper 'task_curr()'
which means we are now dependant on a patched kernel.

* : Tag spl-0.2.1
* modules/spl/spl-proc.c : Add /proc/sys/spl/version.

* include/sys/kmem.h : Make sure that when calling __vmem_alloc
that we do not have __GFP_ZERO set. Once the memory is allocated
then zero out the memory if __GFP_ZERO is passed to
__vmem_alloc.

* modules/spl/spl-kmem.c : Make sure to disable interrupts
when necessary to avoid deadlocks. We were seeing the deadlock
when calling kmem_cache_generic_constructor() and then an interrupt
forced us to end up calling kmem_cache_generic_destructor()
which caused our deadlock.

: Initial commit of the solaris porting layer (spl). Included
in addition to the source is an initial autoconf / configure
style build system.
