This change adds exposure of a new transceiver method for getting
the total set of supported extensions stored as an attribute,
and their direction. If the direction is kStopped, the extension
is not signalled in Unified Plan SDP negotiation.
Note: SDP negotiation is not modified by this change.
Changes:
- RtpHeaderExtensionCapability gets a new RtpTransceiverDirection,
indicating either kStopped (extension available but not signalled),
or other (extension signalled).
- RtpTransceiver gets the new method as described above. The
default value of the attribute comes from the voice and video
engines as before.

It can only be one of four possible values, so it never made sense
for it to be a double. Other than the fact that its neighbor
bitrate_priority is a double, and they're both defined as the same enum
in the web spec. However, while bitrate_priority being a double
offers more flexibility than the web spec, network_priority being a
double is only confusing.

This change adds the writing and parsing of the `abs-capture-time` RTP header extension defined at:
http://www.webrtc.org/experiments/rtp-hdrext/abs-capture-time
We are still missing the code to:
- Negotiate the header extension.
- Collect capture time for audio and video and have the info sent with the header extension.
- Receive the header extension and use its info.

This CL uses RTC_EXPORT (defined in rtc_base/system/rtc_export.h)
to mark WebRTC symbols as visible from a shared library, this doesn't
mean these symbols are part of the public API (please continue to refer
to [1] for info about what is considered public WebRTC API).

One-byte RTP extensions may only have IDs in the range 1-14.
For higher IDs, the two-byte format must be used.
If default IDs are set for all extensions, once 15 extensions are
defined by the code, some extensions will have IDs greater than 14.
This will happen even if only one extension actually ends up being
offered, so long as it's that unfortunate RTP extension.
It's better to dynamically assign the IDs to those extensions we
actually offer. The code that assigns the IDs is currently
distributed ( WebRtcVoiceEngine::GetCapabilities() and
WebRtcVideoEngine::GetCapabilities()), and without a bigger
refactoring effort would produce some ID collisions and mismatches.
Those are already handled by MergeRtpHdrExts(), so so that
should not be a problem.

Hard-coding default values forces IDs over 14 to be used even
when we offer less than 15 different extensions.
Note that the code relies on MergeRtpHdrExts for making sure
that extension IDs are kept consistent and non-colliding between
different streams (audio/video).
