As described in #11445, the kernel interface kernel_{read,write} no
longer act on special devices. In the ZTS, zfs send and receive are
tested by piping to these devices, leading to spurious failures (for
positive tests) and may mask errors (for negative tests).
Until a more permanent mechanism to address this deficiency is
developed, clean up the output from the ZTS by avoiding directly piping
to or from /dev/null and /dev/zero.
For /dev/zero input, simply use a pipe: `cat </dev/zero |` .
However, for /dev/null output, the shell semantics for pipe failures
means that zfs send error codes will be masked by the successful
`| cat >/dev/null` command execution. In that case, use a temporary
file under $TEST_BASE_DIR for output in favor.

Despite that dracut has a hard dependency on bash,
its modules doesn't, dracut only has a hard dependency on bash for
module-setup (on a fully usable machine). Inside initramfs, dracut
allows users choose from a list of handful other shells, e.g. bash,
busybox, dash, mkfsh.
In fact, my local machine's initramfs is being built with dash,
and it's functional for a very long time.
Before 64025fa3a (Silence 'make checkbashisms', 2020-08-20), we also
allows our users to have that right, too.
Let's fix the problem 'make checkbashisms' reported and allows our users
to have that right, again.
For 'plymouth' case, let's simply run the command inside the if instead
of checking for the existence of command before running it, because the
status is also failture if plymouth is unavailable.
While we're at it, let's remove an unnecessary fork for grep in
zfs-generator.sh.in and its following complicated 'if elif fi' with
a simple 'case ... esac'.
To support this change, also exclude 90zfs from "make checkbashisms"
because the current CI infrastructure ships an old version of
"checkbashisms", which complains about "command -v", while the current
latest "checkbashisms" thinks it's fine. In the near future, we can
revert that change to "Makefile.am" when CI infrastructure is updated.

On systems with musl libc, hostid(1) always prints "00000000", which
will cause improper behavior when the 90zfs module is configured in a
dracut initramfs. Work around this by copying the host /etc/hostid if
the file exists, and otherwise only write /etc/hostid if hostid(1)
returns something meaningful. This avoids zgenhostid creating a random
/etc/hostid for the initramfs, which could lead to errors when trying to
import the pool if spl_hostid isn't defined in the kernel command line.
Furthermore, tag the /etc/hostid file as hostonly, since it is system
specific and shouldn't be taken into account when trying to use an
initramfs generated in one system to boot into a different system.

libtool stores absolute paths in the dependency_libs component of the
.la files. If the Makefile for a dependent library refers to the
libraries by relative path, some libraries end up duplicated on the link
command line.
As an example, libzfs specifies libzfs_core, libnvpair and libuutil as
dependencies to be linked in. The .la file for libzfs_core also
specifies libnvpair, but using an absolute path, with the result that
libnvpair is present twice in the linker command line for producing
libzfs.
While the only thing this causes is to slightly slow down the linking,
we can avoid it by using absolute paths everywhere, including for
convenience libraries just for consistency.

libzutil is currently statically linked into libzfs, libzfs_core and
libzpool. Avoid the unnecessary duplication by removing it from libzfs
and libzpool, and adding libzfs_core to libzpool.
Remove a few unnecessary dependencies:
- libuutil from libzfs_core
- libtirpc from libspl
- keep only libcrypto in libzfs, as we don't use any functions from
libssl
- librt is only used for clock_gettime, however on modern systems that's
in libc rather than librt. Add a configure check to see if we actually
need librt
- libdl from raidz_test
Add a few missing dependencies:
- zlib to libefi and libzfs
- libuuid to zpool, and libuuid and libudev to zed
- libnvpair uses assertions, so add assert.c to provide aok and
libspl_assertf
Sort the LDADD for programs so that libraries that satisfy dependencies
come at the end rather than the beginning of the linker command line.
Revamp the configure tests for libaries to use FIND_SYSTEM_LIBRARY
instead. This can take advantage of pkg-config, and it also avoids
polluting LIBS.
List all the required dependencies in the pkgconfig files, and move the
one for libzfs_core into the latter's directory. Install pkgconfig files
in $(libdir)/pkgconfig on linux and $(prefix)/libdata/pkgconfig on
FreeBSD, instead of /usr/share/pkgconfig, as the more correct location
for library .pc files.

The device_rebuild feature enables sequential reconstruction when
resilvering. Mirror vdevs can be rebuilt in LBA order which may
more quickly restore redundancy depending on the pools average block
size, overall fragmentation and the performance characteristics
of the devices. However, block checksums cannot be verified
as part of the rebuild thus a scrub is automatically started after
the sequential resilver completes.
The new '-s' option has been added to the `zpool attach` and
`zpool replace` command to request sequential reconstruction
instead of healing reconstruction when resilvering.
zpool attach -s <pool> <existing vdev> <new vdev>
zpool replace -s <pool> <old vdev> <new vdev>
The `zpool status` output has been updated to report the progress
of sequential resilvering in the same way as healing resilvering.
The one notable difference is that multiple sequential resilvers
may be in progress as long as they're operating on different
top-level vdevs.
The `zpool wait -t resilver` command was extended to wait on
sequential resilvers. From this perspective they are no different
than healing resilvers.
Sequential resilvers cannot be supported for RAIDZ, but are
compatible with the dRAID feature being developed.
As part of this change the resilver_restart_* tests were moved
in to the functional/replacement directory. Additionally, the
replacement tests were renamed and extended to verify both
resilvering and rebuilding.
