libctf, dedup: add new configure option --enable-libctf-hash-debugging
Add a new debugging configure option, --enable-libctf-hash-debugging, off by default, which lets you configure in expensive internal consistency checks and enable the printing of debugging output when LIBCTF_DEBUG=t before type deduplication has happened. In this commit we just add the option and cause it to turn ctf_assert into a real, hard assert for easier debugging. libctf/ * configure.ac: Add --enable-libctf-hash-debugging. * aclocal.m4: Pull in enable.m4, for GCC_ENABLE. * Makefile.in: Regenerated. * configure: Likewise. * config.h.in: Likewise. * ctf-impl.h [ENABLE_LIBCTF_HASH_DEBUGGING] (ctf_assert): Define to assert.
