Add BytesToMiB for ulong.
Rename "HttpClients" to "HttpClientFactory".
Add WP8.1 BackgroundMediaPlayer support.
It doesn't really work yet...
Add UserAgentExtensions.
Add HttpConnection and HttpConnectionReader.
They do HTTP and HTTPS GETs with StreamSocket.
Reduce debug noise.
Add ASCII and Latin1 text encodings (from Mono).
Try harder to find text encodings; fall back to the Mono implementations.
Move platform HttpSocket files to HttpConnection to be consistent with SM.Media.
The test for seq_scaling_list_present_flag was wrong.
See 7.3.2.1.1 in Rec. ITU-T H.264 (04/2013).
