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.
