35fa280229 Adds allocated rate without feedback to new congestion controller.
When bitrate is allocated to streams that does not have packet feedback,
the allocated bitrate should be included in the estimate. This was
previously only implemented for the old congestion controller and not
for the new task queue based version.

To make the behavior more robust, the responsibility for tracking this
is moved to BitrateAllocator where it's handled consistently for
multiple streams without feedback.

96ede16a4e Enable -Wexit-time-destructors and -Wglobal-constructors.
This CL enables -Wexit-time-destructors and -Wglobal-constructors on
rtc_static_library and rtc_source_set build targets.

It also adds the possibility to suppress these warnings because
they trigger in a few places.

The long term goal is to avoid regressions on this and remove all the
suppressions.

9de4ef4b24 Adds signed infinity to timestamps.
Negative infinity is useful in comparisons as it represents a value
guaranteed to be less than any other timestamp. This avoid using
Timestamp::ms(0) to represent such a value or having to use optional
for the special case of first time execution.

To avoid ambiguity, Timestamp::Infinity is renamed to PlusInfinity.

ed1f75ab6d Removes redundant starting rate.
Sine a starting rate field was added to the constraints struct. Having
it in the initial config separately is reduntant. To simplify the code,
the extra field is removed. This is a follow up on:

ea9249ed15 Network & bitrate controllers are added for PCC.
Network controller is an implementation of the
NetworkControllerInterface which is a part of congestion controller API.
Bitrate controller computes rate update each iteration (see
https://www.usenix.org/system/files/conference/nsdi18/nsdi18-dong.pdf).

9171e78ccd Adds monitor interval class for PCC.
The PCC congestion control algorithm divides time into consecutive
intervals called monitor intervals. This CL adds a class that is used by
PCC to measure the performance of sending at a certain rate during one
monitor interval.
