Update libsanitizer obstack interceptors

New obstack uses sensible types, size_t instead of int for length
params.  Since libsanitizer does not use prototypes from obstack.h to
call the real functions, it's necessary to update the libsanitizer
function declarations emitted by the INTERCEPTOR macro.

	* sanitizer_common/sanitizer_common_interceptors.inc: Update size
	params for _obstack_begin_1, _obstack_begin, _obstack_newchunk
	interceptors.
	* configure.ac: Substitute OBSTACK_DEFS.
	* asan/Makefile.am: Add OBSTACK_DEFS to DEFS.
	* tsan/Makefile.am: Likewise.
	* configure: Regenerate.
	* Makefile.in: Regenerate.
	* asan/Makefile.in: Regenerate.
	* interception/Makefile.in: Regenerate.
	* libbacktrace/Makefile.in: Regenerate.
	* lsan/Makefile.in: Regenerate.
	* sanitizer_common/Makefile.in: Regenerate.
	* tsan/Makefile.in: Regenerate.
	* ubsan/Makefile.in: Regenerate.
