Also changes WAV encoding to use source quality instead of fixed 44100/16/2.
Sets the default to WAV, since it has the best quality, and doesn't have the
delay that creating an MP4 container for ALAC currently has (TODO prepare
the headers to avoid the delay).
Ref issue #1182 and #1665
New default for "trusted_networks" = "lan". This will check peer addresses
against the addresses/netmasks of the interfaces to establish whether the peer
is local.
Fixes#1754
- Calculate size for both formats (+ move the return to transcode_encode_query)
- Let transcode_needed() decide what format to output
- Determine content-type from transcoding type
- Add transcode-dependent ability to override file metadata in rsp/daap
- Send file size matching format
Using worker threads instead of httpd threads means that we, not libevent,
decide which requests get handled by which threads. This means that we can
make sure blocking requests (e.g. volume changes) don't get in the way of
realtime(ish) stuff like mp3 streaming.
Includes refactor of httpd_stream_file() since it was a bit of a monster.
Despite that it seemingly supports multithreading it picks threads that are
busy, and not sure how that can be prevented. Also libevhtp is currently
unmaintained.
