Convert atomic_ops_malloc.c to valid C++ code

Explicit pointer casts are added where necessary.

* src/atomic_ops_malloc.c [HAVE_MMAP] (get_mmaped): Cast result of
mmap() to char* (when assigned to "result" local variable).
* src/atomic_ops_malloc.c (AO_free): Cast AO_free_large() argument
to char*.
