[PATCH 0/3 v4] Common code cleanups (part 1)

[Gary Benson <gbenson@redhat.com>]

Hi all,

This series contains the lateset versions of the first three patches
from the common code cleanups series I've posted previously.  I intend
to rework and resubmit the remaining patches, but these three are I
think ready to go in and it would be nice to get them out of my hair.

Patch 1/3 (Introduce common/errors.h) has had everything to do with
fatal removed.  The remaining functions have updated documentation
which I hope is now ok.  Everything else is unchanged from the
previous versison.

Patch 2/3 (Remove some GDBSERVER checks from linux-ptrace) has been
updated to reverse some logic to avoid indentation changes which will
likely be reversed as further code is merged.  It has also been
updated to not mutate the additional_flags static global.

Patch 3/3 (Make gdbserver CORE_ADDR unsigned) is unchanged from the
previous version posted to this list.  It's been approved already,
but I'm including it here for completeness.

Built and regtested on RHEL6.5 x86_64.

Is this ok to commit?

Thanks,
Gary
