the error path needs an initialized bufferevent too, otherwise it'll crash when trying to write the response. This moves the initialisation early, right after the tls_handshake. Another option would be to initialise it in do_accept, but that may be too early.

ECONNABORTED is returned if a connections gets aborted after being queued before the accept(2). I had some cases of accept: Software caused connection abort on FreeBSD, this should avoid that.

This adds a barebone dumping of the parsed configuration. It is not complete, but I'm interested in dumping the full path to `cert' and `key' in order to write some scripts that can inspect the configuration, extract the certificates and renew them when expired automatically. It's not easy to parse gmid configuration otherwise because the syntax is flexible and users can use macros. Instead, the idea is to run gmid and let it dump the configuration once it's been parsed in a static and predictable format. Now is possible to parse gmid configuration with, say, awk or perl.

It's been there for a long time, and it's frankly annoying to pretend to use parameters. Most of the time, they're there to satisfy an interface and nothings more.
