[PATCH v2 08/16] don't check for stddef.h

gdb already unconditionally includes stddef.h in many places.
I think there is no reason to check for its existence.
Also, Zack Weinberg's header file survey agrees:
http://hacks.owlfolio.org/header-survey/
This patch removes the configure check and the inclusion guards.
It also removes a redundant inclusion that I noticed in defs.h.

* config.in: Rebuild.
* configure: Rebuild.
* configure.ac: Don't check for stddef.h.
* defs.h: Unconditionally include stddef.h. Remove duplicate
inclusion.
