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.

It was discovered that dracut scripts and zgenhostid
always generate little-endian /etc/hostid.
This commit provides simple endianess-aware binary
and updates the scripts to use it.
New features include:
-f flag to force overwrite.
-o flag to write to different file (for dracut)
accepting both 0x01234567 and 01234567 values as input

Unlike other filesystems, snapshots and rollbacks of bootfs need to be
done from a rescue environment. This patch makes it possible to snap-
shot or rollback the bootfs simply by specifying bootfs.snapshot or
bootfs.rollback on the kernel command line. The operation will be
performed by dracut just before bootfs is mounted.

Not all systems / distros have a `/bin/bash`, and these scripts are
more difficult to run at development time.
For example, my system is NixOS which doesn't have a /bin/bash. This
is not a problem for NixOS building ZFS as a package: the build
environment automatically replaces these shebangs with corrected
paths.
The problem is much more annoying at development time: either the
scripts don't run, or I correct them for my local machine and deal with
a perpetually dirty work tree.
Before committing this patch I confirmed there are existing scripts
which use `/usr/bin/env` to locate bash, so I am thinking this is a
safe transformation.
There are a handful of other shebangs in this repository which don't
work on my system. This patch is useful on its own specifically for
`commitcheck.sh`, otherwise I can't validate my commits before
submission.
Here are the remaining shebangs which NixOS systems won't have:
1274 #!/bin/ksh -p
91 #!/bin/ksh
89 #! /bin/ksh -p
2 #!/bin/sed -f
1 #!/usr/bin/perl -w
1 #!/usr/bin/ksh
1 #!/bin/nawk -f
plus this which will create an invalid shebang in
`tests/zfs-tests/tests/functional/mv_files/mv_files_common.kshlib`:
echo "#!/bin/ksh" > $TEST_BASE_DIR/exitsZero.ksh
I chose to leave those alone for now, and gauge the interest in this
much smaller patch first.
The fixes for these are easy enough by simply using `/usr/bin/env ksh`:
91 #!/bin/ksh
1 #!/usr/bin/ksh
The fix for the other set is much trickier. Quoting the GNU coreutils
manual:
Most operating systems (e.g. GNU/Linux, BSDs) treat all text after
the first space as a single argument. When using env in a script it
is thus not possible to specify multiple arguments.
and not all `env`'s support arguments.
Mine (GNU Coreutils 8.31) does, though this feature is new since
April 2018, GNU Coreutils 8.30:
https://git.savannah.gnu.org/cgit/coreutils.git/commit/?id=668306ed86c8c79b0af0db8b9c882654ebb66db2
and worse, requires the -S argument:
-S, --split-string=S process and split S into separate arguments;
used to pass multiple arguments on shebang
lines
Example:
$ seq 1 2 | $(nix-build '<nixpkgs>' -A coreutils)/bin/env "sort -nr"
/nix/[...]-coreutils-8.31/bin/env: ‘sort -nr’: No such file or directory
/nix/[...]-coreutils-8.31/bin/env: use -[v]S to pass options in shebang lines
$ seq 1 2 | $(nix-build '<nixpkgs>' -A coreutils)/bin/env "-S sort -nr"
2
1
GNU Coreutils says FreeBSD's `env` does, though I wonder if FreeBSD's
would be unhappy with the `-S`:
https://www.gnu.org/software/coreutils/manual/html_node/env-invocation.html#env-invocation
BusyBox v1.30.1 does not, and does not have a `-S`-like option:
$ seq 1 2 | $(nix-build '<nixpkgs>' -A busybox)/bin/env "sort -nr"
env: can't execute 'sort -nr': No such file or directory
Toybox 0.8.1 also does not, and also does not have a `-S` option:
$ seq 1 2 | $(nix-build '<nixpkgs>' -A toybox)/bin/env "sort -nr"
env: exec sort -nr: No such file or directory
---
At any rate, if this patch merges and the remaining ~1,500 are updated,
the much larger patch should probably include a checkstyle-like test
asserting all new shebangs use `/usr/bin/env`. I also don't mind
dealing with NixOS weirdness if the project would prefer that.

vdev_id requires the program `basename` when handling short aliases
defined in `vdev_id.conf` (those defined without a leading path), but
`basename` is not always available in the dracut environment. This
causes the pool device names to change when using `by-vdev/` devices
or (in extreme cases) can make the pool import fail in dracut.
This commit fixes the problem by explicitly installing `basename`.

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
'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.

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
