Alexander Gryanko 9fff62e2a8 Qt, http2: Add Follow HTTP/2 Stream functionality
The HTTP/2 protocol multiplexes a single TCP connection into multiple
independent streams. The Follow TCP output can interleave multiple
HTTP/2 streams, making it harder to analyze a single HTTP/2 stream.

Add the ability to select HTTP/2 Streams within a TCP stream.
Internally, the HTTP/2 dissector now stores the known Stream IDs in a
set for every TCP session which allows an amortized O(n) lookup time for
the previous/next/max Stream ID.

[Peter: make the dissector responsible for clamping the HTTP/2 Stream ID
instead of the Qt code, that should permit future optimizations.]
