The tests were not honoring packet boundaries, thus causing failures
in tests with dropped/broken packets. This CL fixes this and also
re-enables the tests.

The current use of rtc::FifoBuffer can lead to reading across DTLS packet
boundaries which could cause packets to not being processed correctly.
This CL introduces the new class rtc::BufferQueue and changes the
StreamInterfaceChannel to use it instead of the rtc::FifoBuffer.
