Some clients aren't really capable of authenticating + some users probably
don't want to enter a password for the web interface. This option allows
clients on for instance the local network to connect without authentication.
Make it easier to add new parameters later, get rid of redundant code, clean
up, align between httpd_xxx modules and introduce new bugs. Yes, the refactor
got a bit out of hand.
iTunes and Roku devices do not encode + as %2B in the query string and
do not encode space as + either in the query string (though at least the
Roku encode space as %20 everywhere). This needs to be worked around or
browse queries fail to parse because + was decoded as space when the query
really needs a + character.
Transcoding is not supported yet.
In the current state of affairs, we will crash if the client closes the
connection before the tranfser is done. This is a limitation of evhttp,
it is not possible to detect this condition. This will need to be fixed
in evhttp.
