Code in function kdump_install_net used to get server of network dump
is is a little redundent, can be optimized into one line. For nfs/ssh,
this line of code is enough.

Currently on fedora directory name of kdump is like 14.11.12-03:40:30.
It's not as readable as RHEL6. The old format of dir is host_ip-date-time.
This patch changes it back like ole one as below.

If can't get HOST_IP for a network kudmp, we just fail. Becasue most

ssh: add random feeding code
openssh usually depends on /dev/urandom to seeding PRNG (pseudo-random number
generator). To ensure there's sufficient entropy just feed /dev/urandom with
saved /var/lib/random-seed which is saved in installing phase.
dracut_install will print error message, so just exit and do not print error
again.
Todo: other dracut_install fail and exit, such as dd, makedumpfile.

Original host_fs_types could only contain one iscsi slave,
This is due to the check_block_and_slaves will return once the helper function
return TRUE, so only one slave with fs type will be added to host_fs_types[]
Thus, there will no chance to setup other slaves in kdump iscsi setup routine.
Use for_each_host_dev_and_slaves_all to setup all slaves.
Tested by chaowang and myself.

Currently net options means either nfs or ssh dump.
Better to split these two into standalone options. That's more clear to user.
after the split, ssh dump need user specify "ssh user@host"
nfs dump need user specify "nfs host:nfsshare"

Update: error out vlan over bridge case
This patch adds support for vlan tagged bonding,
in theory, we could support other complex setup as well,
in practice, this is not easy, so just support vlan
tagged bonding, which is the one we support in RHEL6.
Note, this patch depends on the dracut patch:

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,

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.

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
