OpenZFS-issue: https://www.illumos.org/issues/7431
OpenZFS-commit: https://github.com/openzfs/openzfs/commit/dfc11533
Porting Notes:
* The CLI long option arguments for '-t' and '-m' don't parse on linux
* Switched from kmem_alloc to vmem_alloc in zcp_lua_alloc
* Lua implementation is built as its own module (zlua.ko)
* Lua headers consumed directly by zfs code moved to 'include/sys/lua/'
* There is no native setjmp/longjump available in stock Linux kernel.
Brought over implementations from illumos and FreeBSD
* The get_temporary_prop() was adapted due to VFS platform differences
* Use of inline functions in lua parser to reduce stack usage per C call
* Skip some ZFS Test Suite ZCP tests on sparc64 to avoid stack overflow

The on-disk format for encrypted datasets protects not only
the encrypted and authenticated blocks themselves, but also
the order and interpretation of these blocks. In order to
make this work while maintaining the ability to do raw
sends, the indirect bps maintain a secure checksum of all
the MACs in the block below it along with a few other
fields that determine how the data is interpreted.
Unfortunately, the current on-disk format erroneously
includes some fields which are not portable and thus cannot
support raw sends. It is not possible to easily work around
this issue due to a separate and much smaller bug which
causes indirect blocks for encrypted dnodes to not be
compressed, which conflicts with the previous bug. In
addition, the current code generates incompatible on-disk
formats on big endian and little endian systems due to an
issue with how block pointers are authenticated. Finally,
raw send streams do not currently include dn_maxblkid when
sending both the metadnode and normal dnodes which are
needed in order to ensure that we are correctly maintaining
the portable objset MAC.
This patch zero's out the offending fields when computing
the bp MAC and ensures that these MACs are always
calculated in little endian order (regardless of the host
system's byte order). This patch also registers an errata
for the old on-disk format, which we detect by adding a
"version" field to newly created DSL Crypto Keys. We allow
datasets without a version (version 0) to only be mounted
for read so that they can easily be migrated. We also now
include dn_maxblkid in raw send streams to ensure the MAC
can be maintained correctly.
This patch also contains minor bug fixes and cleanups.

'zfs load-key -a' will only be called if needed. If a dataset not
needed for boot does not have its key loaded (home directories for
example) boot can still continue.
zfs:AUTO was not working via dracut, so we still need the generator
script to do its thing.

* HKDF implementation moved to its own file and tests
added to ensure correctness.
* Removed libzfs's now unnecessary dependency on libzpool
and libicp.
* Ztest can now create and test encrypted datasets. This is
currently disabled until issue #6526 is resolved, but
otherwise functions as advertised.
* Several small bug fixes discovered after enabling ztest
to run on encrypted datasets.
* Fixed coverity defects added by the encryption patch.
* Updated man pages for encrypted send / receive behavior.
* Fixed a bug where encrypted datasets could receive
DRR_WRITE_EMBEDDED records.
* Minor code cleanups / consolidation.

On Void Linux (x86_64 musl) libgcc_s.so is located in "/usr/lib"
so it is not found by dracut and it produces an error.
Add a simple additional path check for "/usr/lib/libgcc_s.so*"
and install it in the initramfs.

while these are source by dracut (which is a bash script)
the practical difference is small, but it is more correct:
/bin/sh is not bash on all systems (e.g. Debian and its
derivatives use /bin/dash as /bin/sh by default).

When Dracut starts up, it needs to determine whether a pool will remain
"hanging open" before the system shuts off. In such a case, then the
code to clean up the pool (using the previous export -F work) must
be invoked. Since Dracut has had a recent change that makes
mount-zfs.sh simply not run when the root dataset is already mounted,
we must use the cleanup hook to order Dracut to do shutdown cleanup.
Important note: this code will not accomplish its stated goal until this
bug is fixed: https://bugzilla.redhat.com/show_bug.cgi?id=1385432
That bug impacts more than just ZFS. It impacts LUKS, dmraid, and
unmount during poweroff. It is a Fedora-wide bug.

The behavior of the Dracut module was very wrong before.
The correct behavior: initramfs should not run `zfs-mount` to completion
if the two generator files exist. If, however, one of them is missing,
it indicates one of three cases:
* The kernel command line did not specify a root ZFS file system, and
another Dracut module is already handling root mount (via systemd).
`mount-zfs` can run, but it will do nothing.
* There is no systemd to run `sysroot.mount` to begin with.
`mount-zfs` must run.
* The root parameter is zfs:AUTO, which cannot be run in sysroot.mount.
`mount-zfs` must run.
In any of these three cases, it is safe to run `zfs-mount` to completion.
`zfs-mount` must also delete itself if it determines it should not run,
or else Dracut will do the insane thing of running it over and over again.
Literally, the definition of insanity, doing the same thing that did not
work before, expecting different results. Doing that may have had a great
result before, when we had a race between devices appearing and pools
being mounted, and `mount-zfs` was tasked with the full responsibility
of importing the needed pool, but nowadays it is wrong behavior and
should be suppressed.
I deduced that self-deletion was the correct thing to do by looking at
other Dracut code, because (as we all are very fully aware of) Dracut
is entirely, ahem, "implementation-defined".

Based upon @ryao's initial fix for 1c73494394fc9de9283b3fd4f00bcdf4bd300a7
( 5e9843405f63fdabe76e87b92b81a127d488abc7 ) this one also uses
`command -v` instead of `type`, but additionally only applies the
fix to close zfsonlinux/zfs#4749 when `libgcc_s.so.1` has not been included
by dracut automatically (verified by whether `zpool` links directly to
`libgcc_s.so`), as well as change the fallback option to match `libgcc_s.so*`.

Build products from an out of tree build should be written
relative to the build directory. Sources should be referred
to by their locations in the source directory.
This is accomplished by adding the 'src' and 'obj' variables
for the module Makefile.am, using relative paths to reference
source files, and by setting VPATH when source files are not
co-located with the Makefile. This enables the following:
$ mkdir build
$ cd build
$ ../configure \
--with-spl=$HOME/src/git/spl/ \
--with-spl-obj=$HOME/src/git/spl/build
$ make -s
This change also has the advantage of resolving the following
warning which is generated by modern versions of automake.
Makefile.am:00: warning: source file 'xxx' is in a subdirectory,
Makefile.am:00: but option 'subdir-objects' is disabled
