[libbacktrace] Avoid realloc with size == 0 in backtrace_vector_release
As of C17, realloc with size 0 is marked as an obsolescent feature.
Fix this in backtrace_vector_release by using free instead.
Bootstrapped and reg-tested on x86_64.
2018-11-27 Tom de Vries <tdevries@suse.de>
* alloc.c (backtrace_vector_release): Handle vec->size == 0 using free
instead of realloc.
* Makefile.am (check_PROGRAMS): Add unittest.
* Makefile.in: Regenerate.
* unittest.c: New file.
