Intel MPX bound violation support.
First 5 patches of the series are preparation for the
bound violation handler.
Preparation:
Fixup implementation for GDB and gdbserver of siginfo
types for x32 and 32bits inferior running on 64bits are merged.
It was added a simple way to add fields in the
siginfo structure for all architectures.
For i386/amd64 the dependency on the siginfo where
GDB/gdbserver for the usage and display was eliminated.
Now GDB descriptions of this type are enough for display
Bound violation information can be seen in the last commit of
the series.
>From V3 to V4:
* Changed changelog and added Pedro's comments on 1/6.
* Added Pedro's feedback on 3/6.
* News is added into 6/6.
Thanks for the review and regards,
