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.

grammar

make gemini_parse_reply() return -1 on error

don't pause the request in gemini_parse_reply() a parse routine shouldn't interfere with the handling of the events; pulling this into the caller makes the logic simpler to follow.

simplify gemini_parse_reply()

simplify gemini header handling with buf_getdelim()

decouple bufio from ev more a matter of cleanliness than a strong reason, but this allows to reuse bufio without ev (if wanted to.)

net: initialize fds earlier

net: use a single timer for asr and handshake timeout

move imsgev & co to their own file This avoids bringing the dependency on ev on telescope-identity(1) and the tests as well.

net: re-enable asr_run Make asr_run() work on top of ev. While here, rename the function names and add real error checking.

add a paranoic check

add missing return otherwise we try to reschedule the socket we've just closed.

convert telescope to use ev instead of libevent libevent is a very cool library, I like the APIs and enjoy using it. However, telescope is not as large and doesn't have as many file descriptor, so libevent is quite ``too big'' for our needs. ev started as a small event loop on top of poll(2) for amused, and can be used here too, it just needed to grow the ability to handle several timers, as we need quite some on telescope (in fact, we use more timers than fds!)
