it's not so useful here and not (directly) used anywhere else.

and don't forget to free the current config!

adjust the logging level and forward it to every client process so they can do so too.

We may want to be able to run multiple listener process eventually, so the first step is to drop IMSG_CONTROLFD and keep the ctl stuff in the main process.

Drop the IMSG_AUTH_DIR imsg type and stuff everything in a struct kd_auth_proc that gets sent via IMSG_AUTH. Tweak the necessary bits to compile. While here also start documenting what data we send over which imsg. As an added benefit, now we're sending fixed-size messages instead of variable length strings.

Trying to maintain two branches was impossible at this stage for me alone, so I'll recognize my stupidity and merge the portable branch into the main one. The repository will build using autotools.

use by default the OpenBSD mk infrastructure to build and test all the kamid components.
