Original patch is from Amerigo, but it has changed a lot:
remove multi dump
refreshed with latest git for the dump instruction function restructure
fixed the behavior of do_kdump_pre, if kdump_pre fails it will reboot
update the docs
check the existance and executable of kdump_pre/post files,
also check the timestamp of them for rebuilding.
refresh patch,
Address comments from vivek:
s/hush/bash in docs
fix the copy-paste error in kdump post error message
s/reboot\/halt/reboot in kexec-kdump-howto.txt

1. only append '-F' for default core_collector internally
2. error out if user does not add '-F' for makedumpfile
v1->v2: refresh because of new core collector verify function
v2->v3: optimize the code, remove local variable for default core_collector

1. add core_collector filter support to ssh dump
2. scp can be specified in kdump.conf
3. error out if no '-F' with makedumpfile
4. add proper explanation and examples to kdump.conf[.5] and kexec-kdump-howto.txt.
v1->v2: add verify_core_collector function

move conf_file as a global variable to the top.
vivek: return earlier if kdump.conf is not found in read_kdump_conf to
avoid the deep indent.

let add_dump_code only deal with real dump instruction,
move other logic out of that function, so it's easier for future features
like kdump_pre and kdump_post.

default action is handled in DUMP_INSTRUCTIONI. If default_action failed
current logic will cause mount_root_run_init, It does not make much sense.
changes to: let reboot -f does not depend on return status of DUMP_INSTRUCTION

Do not reboot in dump_rootfs function, also do not directly call dump_rootfs
for default dump. Instead just adding it to DUMP_INSTRUCTION as other
user specified dump target.

currently kexec-tools maintains kdump dracut modules as below dir hierarchy:
[dave@localhost fedpkg]$ tree kexec-tools/kdump_dracut_modules
kexec-tools/kdump_dracut_modules
`-- 99kdumpbase
|-- kdump.sh
`-- module-setup.sh
But in kexec-tools.spec, sources line is below:
Source100: dracut-files.tbz2
So we need to manually generate the dracut-files.tbz2, upload it, modify
the sources file which contains the md5sum of these binaies, and then do
the building. The more headache problem is this make local tests of
changes to kdump module hard.
To ease future work, move the files to TOPDIR, cp the sources instead.
Thanks for help from dzickus
[v1->v2]: Also remove dracut-files.tbz2 from sources file
ChaoWang: add prefix to dracut files
