When attaching a vdev to a mirror wait for the resilver to complete
before invoking `zdb` to inspect the pool. This ensures the pool is
essentially idle which allows `zdb` to open the imported pool reliably.

- Replaced intances of `dracut_install` with `inst_simple`
- Removed calls to `test -x mark_hostonly` because the function is an
inbuilt dracut function
- Removed redundant installation of `systemd-ask-password` and
`systemd-tty-ask-password-agent` because they are already installed by
the systemd module. There is no need to install them again
- Removed multiple calls to the `mark_hostonly` function because the
`inst_simple` has a command-line switch for it
- Cleaned up the installation of the `zpool.cache`, `vdev_id.conf` and
`hostid` files to make the logic easier to follow
- Cleaned up and simplified the systemd service installation logic by
invoking systemctl instead of creating symlinks manually
- Replaced various hard-coded paths with dracut equivalents to better
conform with expected dracut behaviour
- Removed redundant call to `mkdir` (`inst_simple` creates the parent
directory if it does not exist on the destination initrd)

Since dracut functions can locate both udev rules and binaries, there is
no point in keeping absolute paths in the module setup script. It also
breaks the --sysroot option in dracut. This commit removes mentions to
absolute paths for binaries and udev rules.

Setting up the module involves multiple redundant calls to a bunch of
dracut functions wheich can be combined into one. Additionally, the mass
of code required to load libgcc_s.so* can be replaced with one dracut
function. This has the additional effect of removing errors involving
the non-installation of libgcc_s.so* which are seen on debian bullseye
when using version 2.1.2-1~bpo11+1 from the backports repository.
The systemd binaries are separated out into their own `dracut_install`
function call so they do not get pulled in when dracut does not load the
systemd module.

Most modern Linux distributions have separate locations for bare
source and prebuilt ("build") files. Additionally, there are `source`
and `build` symlinks in `/lib/modules/$(KERNEL_VERSION)` pointing to
them. The order of directory search is now:
- `configure` command line values if both `--with-linux` and
`--with-linux-obj` were defined
- If only `--with-linux` was defined, `--with-linux-obj` is assumed
to have the same value as `--with-linux`
- If neither `--with-linux` nor `--with-linux-obj` were defined
autodetection is used:
- `/lib/modules/$(uname -r)/{source,build}` respectively, if exist
- The first directory in `/lib/modules` with the highest version
number according to `sort -V` which contains `source` and `build`
symlinks/directories
- The first directory matching `/usr/src/kernels/*` and
`/usr/src/linux-*` with the highest version number according to
`sort -V`. Here the source and prebuilt directories are assumed
to be the same.

Closes#9935Closes#13096
Raw sending from pool1/encrypted with ashift=9 to pool2/encrypted with
ashift=12 results to failure when mounting pool2/encrypted (Input/Output
error). Notably, the opposite, raw sending from a greater ashift to a
lower one does not fail.
This happens because zio_compress_write() falsely checks only
ZIO_FLAG_RAW_COMPRESS and not ZIO_FLAG_RAW_ENCRYPT which is also set in
encrypted raw send streams. In this case it rounds up the psize and if
not equal to the zio->io_size it modifies the block by zeroing out
the extra bytes. Because this happens in a SA attr. registration object
(type=46), the decryption fails upon mounting the filesystem, and zpool
status falsely reports an error.
Fix this by checking both ZIO_FLAG_RAW_COMPRESS and ZIO_FLAG_RAW_ENCRYPT
before deciding whether to zero-pad a block.

ZFS on Linux originally implemented xattr namespaces in a way that is
incompatible with other operating systems. On illumos, xattrs do not
have namespaces. Every xattr name is visible. FreeBSD has two
universally defined namespaces: EXTATTR_NAMESPACE_USER and
EXTATTR_NAMESPACE_SYSTEM. The system namespace is used for protected
FreeBSD-specific attributes such as MAC labels and pnfs state. These
attributes have the namespace string "freebsd:system:" prefixed to the
name in the encoding scheme used by ZFS. The user namespace is used
for general purpose user attributes and obeys normal access control
mechanisms. These attributes have no namespace string prefixed, so
xattrs written on illumos are accessible in the user namespace on
FreeBSD, and xattrs written to the user namespace on FreeBSD are
accessible by the same name on illumos.
Linux has several xattr namespaces. On Linux, ZFS encodes the
namespace in the xattr name for every namespace, including the user
namespace. As a consequence, an xattr in the user namespace with the
name "foo" is stored by ZFS with the name "user.foo" and therefore
appears on FreeBSD and illumos to have the name "user.foo" rather than
"foo". Conversely, none of the xattrs written on FreeBSD or illumos
are accessible on Linux unless the name happens to be prefixed with one
of the Linux xattr namespaces, in which case the namespace is stripped
from the name. This makes xattrs entirely incompatible between Linux
and other platforms.
We want to make the encoding of user namespace xattrs compatible across
platforms. A critical requirement of this compatibility is for xattrs
from existing pools from FreeBSD and illumos to be accessible by the
same names in the user namespace on Linux. It is also necessary that
existing pools with xattrs written by Linux retain access to those
xattrs by the same names on Linux. Making user namespace xattrs from
Linux accessible by the correct names on other platforms is important.
The handling of other namespaces is not required to be consistent.
Add a fallback mechanism for listing and getting xattrs to treat xattrs
as being in the user namespace if they do not match a known prefix.
Do not allow setting or getting xattrs with a name that is prefixed
with one of the namespace names used by ZFS on supported platforms.
Allow choosing between legacy illumos and FreeBSD compatibility and
legacy Linux compatibility with a new tunable. This facilitates
replication and migration of pools between hosts with different
compatibility needs.
The tunable controls whether or not to prefix the namespace to the
name. If the xattr is already present with the alternate prefix,
remove it so only the new version persists. By default the platform's
existing convention is used.
