[PATCH v4 0/2] Improve corefile generation by using /proc/PID/coredump_filter (PR corefile/16902)

[Sergio Durigan Junior <sergiodj@redhat.com>]

This version of the patches incorporates changes suggested by Pedro.

I simplified the patch a lot, and withdrawed some parts of it.  For
example, I am not including a new 'enum memory_mapping_state', nor am I
changing the current behavior/implementation of gcore_create_callback.
IOW, I focused my changes on the Linux portion of the patch, and on the
problem that I am trying to solve: make GDB take the value of
/proc/PID/coredump_filter into consideration when dumping a corefile.

As I explained in
<https://sourceware.org/ml/gdb-patches/2015-03/msg00607.html>, I still
think gcore_create_callback and its callers should be updated, but I
am not proposing this here anymore.  Hopefully, this will make the patch
easier to be approved.
