fccf3c9c56 Add sudo_mmap_{alloc,allocarrary,strdup,free} functions. 
These allocate memory via mmap anonymous regions and store the mapped
size immediately before the returned pointer as an unsigned long.
They are intended to be used in cases where malloc(3) and free(3)
are unsuitable due to concerns about corrupting global state in
multi-threaded programs or signal handlers.
