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

This patch depends on the latest dracut in git.
It adds support of dumping over a vlan device.

This patch fixes dumping over a bonding interface,
we should pass ifname= for all its underlying slaves,
which is required by dracut.
And it separates the code into a different function.

We hardcoded with dhcp in dracut cmdline before.
Fix it by parsing ifcfg to get the proper proto,
echo proper cmdline for both static and dhcp
[v1->v2]: amwang - handle PREFIX as well

BZ: 822701
This patch implements basic software iscsi dump support. Complex iscsi
setups like ibft etc might not work.
iscsi self configuration logic is currenlty part of kdump module. At some
point of time I would like to see it in dracut iscsi module instead of
kdump module when iscsi and other subsystems become self configuration aware
for general boot.
This patch will require work for complex setups. Some of them are.
- IPV6 support
- IBFT support
- Parsing some more advanced parameters and passing to netroot option.

This allows to reuse same function from iscsi setup code too. Also makes
code more modular.

[v1->v2]: vivek: add kdump_ prefix to kdump functions because dracut
source this file

Resolves: bz816864
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
