[PATCH 3/5] crash: rename crash_core to vmcore_info

[Baoquan He <bhe@redhat.com>]

Now only vmcoreinfo handling related code is in crash_core.c, so do the
renaming as follows:
 kernel/{crash_core.c => vmcore_info.c}
 arch/xxx/kernel/{crash_core.c => vmcore_info.c}
 include/linux/{crash_core.h => vmcore_info.h}
 CONFIG_CRASH_CORE   => CONFIG_VMCORE_INFO

And also update the old ifdeffery of CONFIG_CRASH_CORE, including of
<linux/vmcore_info.h> and config item dependency on CRASH_CORE
accordingly.
