[PATCH 0/5] make '-x'/'-i' option unnecessary for re-filtering.

makedumpfile v1.3.4 can read a dumpfile which is kdump-compressed
format instead of /proc/vmcore and re-filter it.

When re-filtering, it is necessary to specify '-x'/'-i' option.
If not specifying, makedumpfile fails like the following:

 # ./makedumpfile -c -d 3 vmcore vmcore.1
 ...
 The dumpfile is saved to vmcore.1
 ...
 #
 # /makedumpfile -c -d 31 vmcore.1 vmcore.2
 vmcore.1 doesn't contain vmcoreinfo.
 Specify '-x' option or '-i' option.
 Commandline parameter is invalid.
 Try `makedumpfile --help' for more information.
 #

For usability, this patchset makes '-x'/'-i' option unnecessary
for re-filtering.
