Add libtpool (thread pools)
...
OpenZFS provides a library called tpool which implements thread
pools for user space applications. Porting this library means
the zpool utility no longer needs to borrow the kernel mutex and
taskq interfaces from libzpool. This code was updated to use
the tpool library which behaves in a very similar fashion.
Porting libtpool was relatively straight forward and minimal
modifications were needed. The core changes were:
* Fully convert the library to use pthreads.
* Updated signal handling.
* lmalloc/lfree converted to calloc/free
* Implemented portable pthread_attr_clone() function.
Finally, update the build system such that libzpool.so is no
longer linked in to zfs(8), zpool(8), etc. All that is required
is libzfs to which the zcommon soures were added (which is the way
it always should have been). Removing the libzpool dependency
resulted in several build issues which needed to be resolved.
* Moved zfeature support to module/zcommon/zfeature_common.c
* Moved ratelimiting to to module/zfs/zfs_ratelimit.c
* Moved get_system_hostid() to lib/libspl/gethostid.c
* Removed use of cmn_err() in zcommon source
* Removed dprintf_setup() call from zpool_main.c and zfs_main.c
* Removed highbit() and lowbit()
* Removed unnecessary library dependencies from Makefiles
* Removed fletcher-4 kstat in user space
* Added sha2 support explicitly to libzfs
* Added highbit64() and lowbit64() to zpool_util.c

Update the zfs module to collect statistics on average latencies, queue sizes,
and keep an internal histogram of all IO latencies. Along with this, update
"zpool iostat" with some new options to print out the stats:

-p: Display numbers in parseable (exact) values.
Also, update iostat syntax to allow the user to specify specific vdevs
to show statistics for. The three options for choosing pools/vdevs are:
Display a list of pools:
zpool iostat ... [pool ...]
Display a list of vdevs from a specific pool:
zpool iostat ... [pool vdev ...]
Display a list of vdevs from any pools:
zpool iostat ... [vdev ...]
Lastly, allow zpool command "interval" value to be floating point:
zpool iostat -v 0.5
