Restore the calloc family.

* src/gmalloc.c (calloc, gcalloc, hybrid_calloc): Restore definitions.
They were lost in a4817d8 but calloc is still (marginally) used in
code statically liked with emacs, so hybrid_calloc is needed.
Also, in the non-hybrid case, we can't get rid of calloc anyway as
other libraries liked with emacs may need it.
* src/conf_post.h: Restore redefinition of calloc to hybrid_calloc.
