Default gco a bug fix and improvements on register restoration for active tasks

Hello Dave,

This patch series for gcore extension module fix a bug and improves
register restoration for active tasks. Could you review these? I'm
going to release these after your review.

In summary,

- The first patch fixes a bug that a target task context is wrongly
specified in the process of getting NT_PRSTATUS on vmcore in
ELF. Without this patch, all the register values but the one of
the task user mannually specifies are unintensionally equal each
other.

- The remainig patches implements register restorement for active
tasks from exception frame and KVMDUMP notes. By this, register
values for active tasks can be correctly restored for KDUMP,
NETDUMP, DISKDUMP and KVMDUMP formats.

Thanks.
HATAYAMA Daisuke

Thanks for your review.

I've understood the procedure. You told me that some times.
The review was to confirm that the usage of crash library is correct.

Well, I'll release a new version soon.

Thanks.

The patches look fine to me -- although it is not necessary for you
to get my review/approval to update the gcore source code. You are the
maintainer, so you can send me an updated gcore.tar.bz2 file whenever
you like, and I will post it on the crash extensions web page.

Thanks,
Dave
