Update RaopAudioHandler to support the min-latency SDP attribute in iOS 5.1.1

[pentateu]

Hi,

First let me say thank you for the great work. I'm building a Android in-car system and I'll use AirPlay to support streaming of iOS audio, photos and video and your project gives me a huge head start.

Now to the issue. When I tested with iOS 5.1.1 the RaopAudioHandler was throwing an exception because one of the SDP attributes have a dash '-' and the regular expression does not support it.

The attribute is: 'min-latency'

I have changed the regular expression to be:

protected static Pattern s_pattern_sdp_a = Pattern.compile("^(\w+):?(.*)$");

That can be improved to be more restrictive, but that is working fine at the moment.

I have also changed it to protected to allow for the JUnit to have access to the field and run the unit tests.

Cheers, Rafael

Will fix. Actually, this is the second or third time a new field added by an iOS upgrade his triggered this type of problem, so I think I'm just going to make all the regexes as lenient as possible. It seems that being strict here doesn't buy us anything.

Ah, actually I think this is already fixed, but only in the STABLE_1_X branch. The master branch is currently unmaintained - I branched off STABLE_1_X because I intended to rewrite the audio handling quite a bit, but then ran out of time. Guess I shouldn't have used the master branch for this...
