convert to imsg_get_type()

use imsg_get_data() instead of accessing imsg.data

rename ibuf arguments to imsgbuf ibuf is just too confusing since there is also the 'struct ibuf'.

don't reply with a STATUS on MODE change This is to help amused-web. Change the ctl to send an extra STATUS after a MODE change to preserve the behaviour.

switch from libevent to a smaller, thin wrapper around poll() libevent is a very cool library, I like its APIs and enjoy using it. However, for amused it is maybe a bit too much since it doesn't deal with too many file descriptors. Amused only needs to monitor one fd for the player process and the currently connected clients. Given that it runs per-user locally, having more than a dozen of fds open is very, very rare.

adjust copyright years

fix my email address used @openbsd.org initially by mistake and got copied around in most files. Since this has nothing to do officially with the OpenBSD project, use my own email address.

fix snprintf call; could return < 0 on conversion failure

remove double ctl_sock check

enrich `amused monitor' reported events The monitor mode now has access to some additional information other than just the name of the event. The `mode' and `seek' events now report the mode status and the position/duration respectively, allowing consumers of `amused monitor' to show correct and coherent information. It helps in particular applications like `amused-monitor' (in contrib/) that show a progress bar for the current song. Before, they had to run their own timers and periodically synchronize using `amused status', now they can just update the state in the same `amused-monitor' event loop.

change default 'status' format to "status,time:oneline,mode:oneline"

show repeat one after all

print the current modes after 'amused consume/repeat'

typo in print_status: now it's mode, not repeat

fix 'amused load' with empty playlist it didn't send the IMSG_CTL_COMMIT final message so it would get stuck. This also makes 'amused flush' redundant since it's possible to 'amused load </dev/null'.
