This change includes updates to the sdp logic, and transceiver
dissociation and also tests these updates. The sdp validation for
unified plan is updated to consider both the stored remote and local
descriptions for an offer, because either could be the most up to date.
This is important when considering a recycled m section. This also
updates to only dissociate a transceiver when we are setting the remote
or local description from an offer. The final small update allows us to
properly create a media description for a transceiver that is not new
but is part of a recycled m section that has only been set locally for
an offer and we are re-offering.

The bug 8432 is caused by trying to connect through a
"link-local" interface (IP address 169.254.0.x/16),
which is listed among the iPhone network interfaces.
The bug is not happening if the link-local network interfaces
are skipped in the ICE candidate gethering process.
To control this behaviour an option - disable_link_local_networks -
is added inside the RTCConfiguration.
It is used to set the new BasicPortAllocatorSession flag -
PORTALLOCATOR_DISABLE_LINK_LOCAL_NETWORKS.
The port allocator flag is added if the configuration option is set.
IPIsLinkLocal IPAddress function and its friends (IPIsLoopback, IPIsPrivate)
are refactored to work on both IPv4 and IPv6.
Unit test IPIsLinkLocal.
Bonus: fix a bug in IPIsLinkLocalV6:
take into account just 10 network mask bits instead of 16.
