/*
Dictionary object type -- mapping from char * to object.
NB: the key is given as a char *, not as a stringobject.
These functions set errno for errors.  Functions dictremove() and
dictinsert() return nonzero for errors, getdictsize() returns -1,
the others NULL.  A successful call to dictinsert() calls INCREF()
for the inserted item.
