OwrImageRenderer: Set constraining caps
transport_agent: Asynchronously resolve the helper server address
Fix API entry point prefixes.
Build without --enable-gtk-doc for linux (since it's broken).
webrtc.js: Improve API error reporting
bridgeserver: Bind to 127.0.0.1
Update scripts for working OpenH264

A patch was needed against the h264parse plugin to always put the
profile into caps so that the openh264dec plugin could work properly.
Only use entityReplace() on the parts of error messages that are external
Update scripts

This includes updating to the GStreamer 1.4 branch rather than using a
specific version. It also includes support for the iOS 8.1 and OS X
10.10 SDKs.
peerhandler: Use 'for' instead of 'forEach' to iterate with index

When using 'return' to continue iterating, 'i' was not properly
incremented, which would cause a media session to be configured with
a media description intended for another media session.
OwrWindowRegistry: Implement registry for mapping tag to window handle

This is just a hash table wrapper with API. The OpenWebRTC API user will
be expected to register tags against window handles before renderers are
created. When the renderer is created, a tag is passed to its
constructor. This tag can then be used to look up the window handle the
renderer is supposed to render into.
OwrVideoRenderer: Make use of the tag=handle window registry

The window handle is looked up from the window registry. If none is
found, the renderer will create its own window, which preserves the
previous default behaviour. Otherwise the window handle will be set on
glimagesink and glimagesink will render into that widget.
