Move mandoc_{realloc,malloc,calloc} out of libmandoc.h and into mandoc.h

so that everybody can use them.  This follows the convention of
libXXXX.h being internal to a library and XXXX.h being the external
interface.  Not only does this allow the removal of lots of redundant
NULL-checking code, it also sets the tone for adding new mandoc-global
routines.
