bash scripts: replace '[ ]' with '[[ ]]' for bash scripts
kdumpctl, mkdumprd, *-module-setup.sh only target bash, since they
only run in first kernel and depend on dracut, and dracut depends
on bash. So use '[[ ]]' to replace '[ ]'.
This is a batch update done with following command:
`sed -i -e 's/\(\s\)\[\s\([^]]*\)\s\]/\1\[\[\ \2 \]\]/g' kdumpctl, mkdumprd, *-module-setup.sh`
and replaced [ ... -a ... ] with [[ ... ]] && [[ ... ]] manually.
See https://tldp.org/LDP/abs/html/testconstructs.html for more details
on '[[ ]]', it's more versatile, safer, and slightly faster than '[ ]'.
This will also help shfmt to clean up the code in later commits.

mkdumprd: display the absolute path of dump location in the check_user_configured_target()
When kdump service fails, the current errors do not display the
absolute path of dump location(marked it as "^"), for example:
kdump: kexec: unloaded kdump kernel
kdump: Stopping kdump: [OK]
kdump: Detected change(s) in the following file(s): /etc/kdump.conf
kdump: Rebuilding /boot/initramfs-4.18.0-304.el8.x86_64kdump.img
kdump: Dump path "/var1/crash" does not exist in dump target "UUID=c202ef45-3ac3-4adb-85e7-307a916757f0"
^^^^^^^^^^^
kdump: mkdumprd: failed to make kdump initrd
kdump: Starting kdump: [FAILED]
Here, it should output the absolute path of dump location with this
format: "<mount path>/<path>". To fix it, let's extend the relative
pathname to the absolute pathname in check_user_configured_target().

When nfs-utils is not installed, mounting as NFS fs would fail.
Currently, the error message is not user-friendly,
mount: /tmp/mkdumprd.HyPGpS/target: bad option; for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount.<type> helper program.
kdump: Failed to mount on xxx for kdump preflight check.

mkdumprd: fix multiple issues with get_ssh_size
Currently get_ssh_size is not working as expected, it should return the
target's available space, but it will include df's header row string as
the result. Fix this issue by only use the last output line.
And the _opt variable will be used as args so it should be an array.
Also remove the awk call, just use `df --output=avail` instead.

kdump-lib.sh: add a config format and read helper
Add a helper `kdump_read_conf` to replace read_strip_comments.
`kdump_read_conf` does a few more things:
- remove trailing spaces.
- format the content, remove duplicated spaces between name and value.
- read from KDUMP_CONFIG_FILE (/etc/kdump.conf) directly, avoid pasting
"/etc/kdump.conf" path everywhere in the code.
- check if config file exists, just in case.
Also unify the environmental variable, now KDUMP_CONFIG_FILE stands for
the default config location.
This helps avoid some shell pitfalls about spaces when reading config.

Author: Hari Bathini <hbathini@linux.ibm.com>
Date: Wed Jun 23 20:06:48 2021 +0530
fadump: isolate fadump initramfs image within the default one
In case of fadump, the initramfs image has to be built to boot into
the production environment as well as to offload the active crash dump
to the specified dump target (for boot after crash). As the same image
would be used for both boot scenarios, it could not be built optimally
while accommodating both cases.
Use --include to include the initramfs image built for offloading
active crash dump to the specified dump target. Also, introduce a new
out-of-tree dracut module (99zz-fadumpinit) that installs a customized
init program while moving the default /init to /init.dracut. This
customized init program is leveraged to isolate fadump image within
the default initramfs image by kicking off default boot process
(exec /init.dracut) for regular boot scenario and activating fadump
initramfs image, if the system is booting after a crash.
If squash is available, ensure default initramfs image is also built
with squash module to reduce memory consumption in capture kernel.
