Fix error handling in buffer.c

* Don't lose old msg on realloc() failure
* Don't dereference NULL on failure when
  buffer = (...)
  if (!buffer) { buffer->len = orig_len; ...}
* To avoid the above pattern, use integer return values:
  "buffer" itself will not change in any case.
* Add missing error handling
