commit 140a1abdc7de2af3283c254cf82435384495b1c0

slightly rework gemini reply handling

- rename `r' to `code'
- defer the buf_drain() call

With libevent we had to free() the header string, whereas buf_getdelim()
returns a string from the buffer itself, so we can safely defer the
drain operation after the sanity checks.
