C99 testsuite readiness: Add missing abort, exit declarations

The execute tests use abort/exit to report failure/success, but
they generally do not declare these functions (or include <stdlib.h>).
This change adds declarations as appropriate.

It would have been possible to switch to __builtin_abort and
__builtin_exit instead.  Existing practice varies.  Adding the
declarations makes it easier to write the GNU-style commit message
because it is not necessary to mention the function with the call
site.

Instead of this change, it would be possible to create a special
header file with the declarations that is included during the
test file compilation using -include, but that would mean that
many tests would no longer build standalone.
