The value is today set to 200 which is too low for an audio packet to trigger sending probes.
For the initial probing, it would be good if audio packets, that may arrive before the first video frame can trigger sending a probe.
Also fix field trial parsing of required number of probes.

1. Add loss threshold for high bandwidth preference. If the average loss ratio is less than the threshold, then the model prefers higher bandwidth candidates. Otherwise, it prefers lower bandwidth candidates. Before, it always prefers higher bandwidth candidate. The default value is 0.99, means it always prefers high bandwidth candidates.
2. Only increase the estimate if the inherent loss (random loss) is equal to/greater than the average loss. If the inherent loss is less than the average loss, then it is oversending, thus should not increase the estimate.

- Filter out very old packets (to ensure that the estimate doesn't drop to zero if sending is paused and later resumed).
- Discard packets older than previously discarded packets (to avoid the estimate dropping after deep reordering.)
- Add tests cases for high loss, deep reordering and paused/resumed streams to unittest.
- Remove some field trial settings that have very minor effect and rename some of the others.
- Change analyzer.cc to only draw data points if the estimators have valid estimates.

The change bounds the estimate increment by MaxIncreaseFactor in DelayedIncreaseWindow after seeing loss. MaxIncreaseFactor is set to 1000 to disable the change by default.
Improve trendline integration: always allow to decrease the estimate, and only allow to increase the estimate if overusing and underusing are not in the state window.
Other improvement: bound candidates by delay based estimate, instance upper bound, and bandwidth limit in the current window.
Clean: remove the flag BackoffWhenOverusing since it has negative impacts when experimenting.

It is hard to add an unit test for this change, because OnTransportPacketsFeedback is the way to change the loss based estimate, and it also changes the lower link capacity.
Thus we cannot track the two values without making changes in goog_cc, which seem to be unecessary.

This is a safe cleanup change since top-level const applied to
parameters in function declarations (that are not also
definitions) are ignored by the compiler. Hence, such changes do
not change the type of the declared functions and are simply
no-ops.
