This replaces the generic libspl atomic.c atomics implementation
with one based on builtin gcc atomics. This functionality was added
as an experimental feature in gcc 4.4. Today even CentOS 7 ships
with gcc 4.8 as the default compiler we can make this the default.
Furthermore, the builtin atomics are as good or better than our
hand-rolled implementation so it's reasonable to drop that custom code.

and the contents and differences of the record files on failure.
- Updated get_vdevs() to properly exclude all top-level vdevs
including raidz3 and draid[1-3].
- Replaced gnudd with dd. This is the only remaining place in the
test suite gnudd is used and it shouldn't be needed.
- The refill_test_env function expects the pool as the first argument
but never sets the pool variable.
- Only fill the test pools to 50% of capacity instead of 75% to help
speed up the tests.

MINVDEVSIZE.

- redundancy_stripe.ksh should not use log_mustnot to check if the
pool is healthy since the return value may be misinterpreted.

Objtool requires the use of a DRAP register while aligning the
stack. Since a DRAP register is a gcc concept and we are
notoriously low on registers in the crypto code, it's not worth
the effort to mimic gcc generated stack realignment.
We simply silence the warning by adding the offending object files
to OBJECT_FILES_NON_STANDARD.

Traversal code, traverse_visitbp() does visit blocks recursively.
Indirect (Non L0) Block of size 128k could contain, 1024 block pointers
of 128 bytes. In case of full traverse OR incremental traverse, where
all blocks were modified, it could traverse large number of blocks
pointed by indirect. Traversal code does issue prefetch of blocks
traversed below indirect. This could result into large number of
async reads queued on vdev queue. So, account for prefetch issued for
blocks pointed by indirect and limit max prefetch in one go.
Module Param:
zfs_traverse_indirect_prefetch_limit: Limit of prefetch while traversing
an indirect block.
Local counters:
prefetched: Local counter to account for number prefetch done.
pidx: Index for which next prefetch to be issued.
ptidx: Index at which next prefetch to be triggered.
Keep "ptidx" somewhere in the middle of blocks prefetched, so that
blocks prefetch read gets the enough time window before their demand
read is issued.

This change adds SIGSTOP and SIGTSTP handling to the issig function;
this mirrors its behavior on Solaris. This way, long running kernel
tasks can be stopped with the appropriate signals. Note that doing
so with ctrl-z on the command line doesn't return control of the tty
to the shell, because tty handling is done separately from stopping
the process. That can be future work, if people feel that it is a
necessary addition.

zfs_crypto_load_key() only works on encryption roots,

To trigger:
truncate -s 40G /tmp/test
dd if=/dev/urandom of=/tmp/k bs=128 count=1 status=none
zpool create -O encryption=on -O keylocation=file:///tmp/k \
-O keyformat=passphrase test /tmp/test

zfs create -o mountpoint=/b test/b
zfs umount test

Key load error: Keys must be loaded for
encryption root of 'test/a' (test).
Key load error: Keys must be loaded for
encryption root of 'test/b' (test).
And only /test was mounted

Remove vestigial uu_open_tmp(). The problems with this implementation
are many, but the primary one is the TMPPATHFMT macro, which is
unused, and always has been.
Searching around for any users leads only to earlier imports of the
same, identical file, i.a. into an apple repository (which does patch
gethrtime() into it and gives us a copyright date of 2007),
and a MidnightBSD one from 2008.
Searching illumos-gate, uu_open_tmp appears, in current HEAD, three
times: in the header, libuutil's mapfile ABI, and the implementation.
This slowly grows up to eight occurrences as one moves back to the root
"OpenSolaris Launch" commit: the header, implementation, twice in
libuutil's spec ABI, twice (with multilib and non-multilib paths) in
libuutil.so's i386 and SPARC binary db ABIs.
That's 2005, and this file was abandonware even then, it's dead code.
The situation is similar for the uu_dprintf() family of functions and
uu_dump(). Nothing in accessibly recorded history has ever used them.

only get a warning (as these may refer to future features not yet in
the library),
* invalid features in files under /etc/zfs/compatibility.d
get an error (as these are presumed to refer to the current system).
2) Improved error reporting from zpool_load_compat.
Note: slight ABI change to zpool_load_compat for better error reporting.
3) compatibility=legacy inhibits all 'zpool upgrade' operations.
4) Detect when features are enabled outside current compatibility set
* zpool set compatibility=foo <-- print a warning
* zpool set feature@xxx=enabled <-- error
