* Cross-platform wrapper for getdelim(): behaves as the POSIX-standard
* getdelim() function.
*
* See `getdelim(3)` for more information.

* Note that this function will use the libc memory allocator -- so any memory
* passed to this function must come from raw_malloc(), and must be freed by
* raw_free() -- don't use tor_malloc() and tor_free() with this.
