This commit adds a relatively thorough test suite for
kdumpctl reset-crashkernel [--fadump=[on|off|nocma]] [--kernel=path_to_kernel] [--reboot]
as implemented in commit 140da74 ("rewrite reset_crashkernel to support
fadump and to used by RPM scriptlet").
grubby have a few options to support its own testing,
- --no-etc-grub-update, not update /etc/default/grub
- --bad-image-okay, don't check the validity of the image
- --env, specify custom grub2 environment block file to avoid modifying
the default /boot/grub2/grubenv
- --bls-directory, specify custom BootLoaderSpec config files to avoid
modifying the default /boot/loader/entries
So the grubby called by kdumpctl is mocked as
@grubby --grub2 --no-etc-grub-update --bad-image-okay --env=$SPEC_TEST_DIR/env_temp -b $SPEC_TEST_DIR/boot_load_entries "$@"
in the tests. To be able to call the actual grubby in the mock function [1],
ShellSpec provides the following command
$ shellspec --gen-bin @grubby
to generate spec/support/bins/@grubby which is used to call the actual grubby.
kdumpctl has implemented its own version of updating /etc/default/grub
in _update_kernel_cmdline_in_grub_etc_default. To avoiding writing to
/etc/default/grub, this function is mocked as outputting its name and
received arguments similar to python unitest's assert_called_with.

Currently there are two issues with unit-testing the functions defined
in kdumpctl and other shell scripts after sourcing them,
- kdumpctl would call main which requires root permission and would
create single instance lock (/var/lock/kdump)
- kdumpctl and other shell scripts directly source files under /usr/lib/kdump/
When ShellSpec load a script via "Include", it defines the__SOURCED__
variable. By making use of __SOURCED__, we can
1. let kdumpctl not call main when kdumpctl is "Include"d by ShellSpec
2. instruct kdumpctl and kdump-lib.sh to source the files in the repo
when running ShelSpec tests
Note coverage/ is added to .gitignore because ShellSpec generates code
coverage results in this folder.

check_config and check_ssh_config both parse /etc/kdump.conf and are
usually used together. The difference between both is that
check_ssh_config does some extra checks on the format of the provided
ssh destination but ignores invalid or deprecated options in the config.
Thus merge check_ssh_config into check_config. Leave the additional
checks on the ssh destination in check_ssh_config but treat it like the
checks done for e.g. the failure_action.
This slightly changes the behavior of 'kdumpctl propagate', which now
fails if kdump.conf contains an invalid value unrelated to ssh. This
change in behavior isn't problematic because 'kdumpctl propagate' always
needs to be followed by a 'kdumpctl start' to have a working kdump
environment. For the situations where 'propagate' fails now the 'start'
would have failed in the past. So the failure only moved one step ahead
in the sequence.

For ssh targets kdumpctl only verifies that the config value has the
correct <user>@<host> format itself. For all other tests, e.g. if the
destination can be reached, it relies on ssh. This allows users to
provide a <host> that isn't the proper hostname but an alias defined in
the ssh_config without failing the tests. If this is done
dracut-module-setup.sh:kdump_get_remote_ip will fail to obtain the
targets ip address. This failure is not detected and thus will not fail
the initramfs creation. The resulting initramfs however doesn't have the
necessary information for setting up the network and thus will fail to
boot.
Prevent the use of alias hostnames by verifying that the given hostname
is the same one ssh would use after parsing the ssh_config.
Note: Don't use getent ahosts to verify that the given host can be
resolved as this requires the network to be up which cannot be
guaranteed when the kdump.conf is parsed.

s390: handle R_390_PLT32DBL reloc entries in machine_apply_elf_rel()
Starting with gcc 11.3, the C compiler will generate PLT-relative function
calls even if they are local and do not require it. Later on during linking,
the linker will replace all PLT-relative calls to local functions with
PC-relative ones. Unfortunately, the purgatory code of kexec/kdump is
not being linked as a regular executable or shared library would have been,
and therefore, all PLT-relative addresses remain in the generated purgatory
object code unresolved. This in turn lets kexec-tools fail with
"Unknown rela relocation: 0x14 0x73c0901c" for such relocation types.
Furthermore, the clang C compiler has always behaved like described above
and this commit should fix the purgatory code built with the latter.
Because the purgatory code is no regular executable or shared library,
contains only calls to local functions and has no PLT, all R_390_PLT32DBL
relocation entries can be resolved just like a R_390_PC32DBL one.

When run tests with 2 VMs, for example nfs/ssh kdump tests, client VM will do the
crash and dump, server VM will do vmcore saving and if-vmcore-exists
check.
Previously, when client VM finishes running, run-test.sh will kill the lead background
process, and then check if server VM has outputted "TEST PASSED" or "TEST FAILED" string.
However it didn't wait for server VM to finish. As a result, the server VM's final
outputs are not collected and checked, leaving the test result as "TEST RESULT NOT FOUND"
sometimes.
For example, the following is the pstree status of $(jobs -p) before it
gets killed. We can see the server VM is still running:

kexec-tools runs hostname binary in the case of fence_kdump. Since this
is a trival dependency and should not block the kexec-tools installation
if non-existent, using weak-dependency to resolve it.

Since kdump-lib-initramfs.sh is included by kdump-lib.sh, and
FENCE_KDUMP_SEND is used by both 1st and 2nd kernel, moving
FENCE_KDUMP_SEND from kdump-lib.sh to kdump-lib-initramfs.sh.

This patch will make zstd as recommended instead of required for
kexec-tools. If zstd command/package is unavaliable, it can failback to invoke
gzip when making kdump initramfs.
Fixes: 0311f6e ("Set zstd as the default compression method for kdump initrd")
