Now when dump target is not specified, separate disk can't be mounted on
"path", e.g /var/crash. However if target is specified, whatever the default
fail action is set, mkdumprd should go ahead and not be failed.
In check_block_dump_target(), the check only on disk is not complete,
NFS and ssh need be filtered too. So introduce is_user_configured_dump_target
to check this.

In function get_block_dump_target(), code block to get user configured
dump disk and get root fs device can be reused by other places. Now
abstract and wrap them into 2 new functions:
get_user_configured_dump_disk()
get_root_fs_device()
And put them into kdump-lib.sh.
Meanwhile change the get_block_dump_target() accordingly.

Add following common variables and function:
$FENCE_KDUMP_CONIFG: configuration file /etc/sysconfig/fence_kdump
$FENCE_KDUMP_NODES: configuration file /etc/fence_kdump_nodes
$FENCE_KDUMP_SEND: executable /usr/libexec/fence_kdump_send
is_fence_kdump(): used to determine if the system is in a cluster and
configured with fence_kdump.

In mkdumprd, strip_comments is not implemented correctly. Since arguments
passed, strip_comments only take $1 and misses others. This caused
problems. Such as below line, current code will only get "makedumpfile"
and pass it to $config_val finally, then parameters for makedumpfile
are missed.
core_collector makedumpfile -c --message-level 1 -d 31
Now modify function strip_comments.

Add function strip_comments into kdump-lib.sh, since it's used by
several files.

Currently in the whole kdump framework, we have some common functions
used across not only mkdumprd context and dracut context, but also 1st
kernel and 2nd kernel. We defined these functions at each script, which
is obviously not decent.
So let's introduce kdump-lib.sh for the shared functions and put it
to /lib/kdump/kdump-lib.sh.
It starts small, as you can see, only 3 functions are extracted. But in
the future more and more common functions can be added.
