Allow cross-origin requests for relay http requests made in Transport API.

Allow cross-origin requests for relay http requests made in Transport API.

Currently, when creating relay sessions the Transport API can make
cross-origin http requests only when the web app has explicit access to
the relay domain. This is not really neccessary because Transport API
can only be used by chromoting client plugin which is trusted.
PPB_URLLoader API allows cross-origin requests for trusted plugins, so
Transport API should be allowed to make them too. Changed
API implementation to allow cross-origin requests.

LGTM

File content/renderer/p2p/port_allocator.cc (right):

content/renderer/p2p/port_allocator.cc:182: // when this code can be used by
untrusted plugins.
Best to create a bug for this and refer to it here.  The bug can mention that
the content of the request we send here is sufficiently limited that restricting
origin may not actually be worthwhile.
