Revert "Removes lock release in PacedSender callback."

This reverts commit 6b9c60b06d04bc519195fca1f621b10accfeb46b.

Reason for revert: Breaks downstream test

Original change's description:
> Removes lock release in PacedSender callback.
> 
> The PacedSender currently has logic to temporarily release its internal
> lock while sending or asking for padding.
> This creates some tricky situations in the pacing controller where we
> need to consider if some thread can enter while we the process thread is
> actually processing, just temporarily busy sending.
> 
> Since the pacing call stack is no longer cyclic, we can actually remove
> this lock-release now.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
