Extend SPL's getf to also acquire fd minor, and set f_file like upstream.
Lets not assume file_vnode_withvid() succeeds
Implement cv_wait_interruptible, and cv_timedwait_interruptible, so that
we can catch signals as expected. Fixes 'zed' slow shutdown (waiting for
process to die)

Clean up warning in TSD.
Bump spl META version and release to match zfs
SPL bmalloc would randomly return already used memory again, due to
it being on the free_list even after returned. This appears to fix it
but unsure why.
Add spinlock around the slices as well, to protect the free_list list.
Missed spinlock destroy in garbage collector.
Add memory debugging features.
Remove extra inlines in function declarations.
cstyle.pl cleanup of spl-bmalloc.c
Print the spl version found in the META file instead of "v0.01"
Add missing definitions of ce_prefix and ce_suffix
Change default to enable_debug_log=no

We don't have support for enable_debug_log=yes at this time.
Add atomic_swap_64().
Rename highbit to highbit64 like Solaris.
Define both highbit and highbit64 until we are updated to 20140805
Show total memory allocated from kernel by SPL by adding new
sysctl. Average appears to be around 50% used, at best 76%, and
worst, 2% (98% wasted).
Implement secpolicy_sys_config() and spl_priv_check_cred()
Expose the vfs_context_kernel() so that we can open disks as root
rather than the current user.
Move the secpolicy_sys_config implementation to #ifdef __OPPLE__

The immediate reason for providing an implementation of the
secpolicy_sys_config privilge check was to work around the bug that
was causing scrub to hang when run without root privilges. Now that
lundman has found an actual fix for that bug, I have disabled the
secpolicy_sys_config implementation and restored
