Fix the sync issue for dump_fs
Previously the sync for dump_fs is problematic, it always
return success according to man 2 sync. So it cannot detect
the error of the dump target is full and not all of vmcore
data been written back the disk, which will leave the vmcore
imcomplete and report misleading log as "saving vmcore
complete".
In this patch, we will use "sync -f vmcore" instead, which
will return error if syncfs on the dump target fails. In
this way, vmcore sync related failures, such as autoextend
of lvm2 thinpool fails, can be detected and handled properly.

virtiofs support for kexec-tools
This patch add virtiofs support for kexec-tools by introducing a new option
for /etc/kdump.conf:
virtiofs myfs
Where myfs is a variable tag name specified in qemu cmdline
"-device vhost-user-fs-pci,tag=myfs".
The patch covers the following cases:
1) Dumping VM's vmcore to a virtiofs shared directory;
2) When the VM's rootfs is a virtiofs shared directory and dumping the
VM's vmcore to its subdirectory, such as /var/crash;
3) The combination of case 1 & 2: The VM's rootfs is a virtiofs shared
directory and dumping the VM's vmcore to another virtiofs shared
directory.
Case 2 & 3 need dracut >= 057, otherwise VM cannot boot from virtiofs
shared rootfs. But it is not the issue of kexec-tools.

dracut-kdump.sh: make it POSIX compatible
POSIX doesn't support keyword `local`, so this commit reduced variable usage.
Heredoc ("<<<") operation is also not supported, so kdump.conf is now pre-parse
into a temp file. Also fixes many POSIX syntax errors.

Merge kdump-error-handler.sh into kdump.sh
kdump-error-handler.sh does nothing except calling three functions,
it can be easily merged into kdump.sh by using a parameter to run the
error handling routine.
kdump-lib-initramfs.sh was created to hold the three shared functions
and related code, so by merging these two files, kdump-lib-initramfs.sh
can be simplified by a lot.
Following up commits will clean up kdump-lib-initramfs.sh.

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.

Fix incorrect vmcore permissions when dumped through ssh
Previously when dumping vmcore to a remote machine through ssh,
the files are created remotely and file permissions are taken
from the default umask value, which making the files accessible to
anyone on the remote machine.
This patch fixed the security issue by setting a customized umask value
before the file creation on the remote machine.
