Joris Vink 80f5425698 Add filemaps.
A filemap is a way of telling Kore to serve files from a directory
much like a traditional webserver can do.

Kore filemaps only handles files. Kore does not generate directory
indexes or deal with non-regular files.

The way files are sent to a client differs a bit per platform and
build options:

default:
  - mmap() backed file transfer due to TLS.

NOTLS=1
  - sendfile() under FreeBSD, macOS and Linux.
  - mmap() backed file for OpenBSD.

The opened file descriptors/mmap'd regions are cached and reused when
appropriate. If a file is no longer in use it will be closed and evicted
from the cache after 30 seconds.

New API's are available allowing developers to use these facilities via:
  void net_send_fileref(struct connection *, struct kore_fileref *);
  void http_response_fileref(struct http_request *, struct kore_fileref *);

Kore will attempt to match media types based on file extensions. A few
default types are built-in. Others can be added via the new "http_media_type"
configuration directive.
