Implements Active-Remote, which is sent to the speaker, so it can use this
to tell us who it is when it makes dacp request with a device-volume update.
These commands are not used by Remote, but some Airplay speakers are
able to make them (e.g. my Sony STR-DN1040).
Also prepare being able to set the device volume property.
Old Airport Express hangs up if we use GET_PARAMETER (despite announcing support
for it...), and since iTunes seems to use OPTIONS we also do that. We weren't
really using the return value of GET_PARAMETER anyway.

Allows adding non-library spotify tracks to be added to the queue. The
path given to queue_add should either be a spotify track, album or
playlist uri.

Huffman tables (despite not being default), which cause ffmpeg to crash
when mjpeg encoder is encoding artwork jpeg's
Adds utility functions to httpd.c for checking the request headers for
either an "If-None-Match" or an "If-Not-Modified-Since" headers. If the
header value is found and it matches the current value for the requested
resource, we return early with a http response code 403 (Not Modified).
If the request header value is not present or does not match we add the
current ETag/Last-Modified values to the response headers and process
the request normally.
The query did not respect the filter and therefor always returned the
number of albums in the library and not the number of albums for the
given query.
Instead of asking a client to first scan the path into a media_file_info
object and afterwards add it to the queue, we now offer a library
function to directly add a path.
The library-source that can handle the given path translates the path
into new queue item(s) and adds them to the queue.
