Daniel Golle 5e4bb476c0 kexec-tools: bump version and add support for crashdump kernel 
split kexec-tools into two packages, kexec and kdump.
* kexec to simply execute a new kernel
* kdump is for loading and collecting debris of a crashed kernel with
  support for kdump forensics.

In order to properly support booting into a crashkernel, an init script
as well as UCI configuration has been added.
As modifying the kernel cmdline is required for this to work in x86
platforms use an uci-defaults script to modify /boot/grub/grub.cfg.

To test collecting crash information, use the 'c' sysrq-trigger, ie.
echo c > /proc/sysrq-trigger

This should result in the crash kernel being executed and (depending
on the configution) dmesg and/or vmcore getting saved.

To check if the crash kernel was loaded properly, use the 'status'
command of the kdump init script.

John Crispin cd96421b19 kexec-tools: bump version from v2.0.4 to v2.0.9. 
- kexec-tools is now distributed with tarballs of .tar.gz and .tar.xz
   format; .tar.bz2 are not provided anymore.
 - Add CONFIG_KEXEC_LZMA for selecting lzma support.

Patches are updated along to:

 - Remove the now unnecessary patch 0004-mips_regdefs.patch.
 - Drop 100-reduce_size.patch because the size reduction is marginal.
 - Allow zlib and lzma support coexist together.  This patch has been
   merged into upstream project.
 - Fix kexec-tools' configure.ac.
 - Fix a few compilation warnings.

Size comparison of stripped binaries of kexec malta target with both
zlib and lzma support enabled.

 - Before: 41447
 - After:  42583
