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.]

Adds a checkbox to the TCP Stream Dialog's "Round-trip-time"

Following the move for widgets directory, moving utils
to the utils directory. Guidelines for this directory are:
- Generic use but not a widget
- Utility functionality used by many classes
Note: additionally all includes affected by this move have been changed
to absolute path includes, instead of relative ones.

Add Goodput graph:
- measures rate of ACKed bytes (including SACKed bytes)
- useful to compare to throughput during slow-start to estimate
bottleneck rate
Add graph selection checkboxes to multi-plot graphs:
- most important for Throughput, since there are good cases
for showing a subset of graphs at once
- also added for Window Scale, since the addition is similar
to that for Throughput
Minor bug fixes:
- allow zoom rect to work when growing in any direction
(not just right and up)
- keep stray mouse clicks from re-doing a previous zoom
- hide rubber band if active when keypress changes mouse mode
to drag
- allow mouse clicks on open space or grpah to return to default focus
(i.e. focus on graph)

Primarily, this adds visual indication of SACK blocks to tcptrace.
In addition:
- cleaned up focus behavior for graph selector and spinboxes
- added time-delay update to streamNumber spinBox
(similar to behavior of maWindow spinBox)
- changed ACK selection to select only SACKed responses
(rather than all ACKs - SACKs seemed more useful to look at)

The time-based moving average code should use a constant window size
as the denominator when calculating throughput.
Added QDoubleSpinbox widget to choose the time-based moving average size.
Also added (optional) ability to select ACK (reverse) packets as well as data
packets when clicking on the base graph.
(useful, for example, when examining SACK or DSACK packets)
Added CheckBox widget (with tooltip) for user to choose ACK selection

Without this, a long hint string (like a wrong protocol name in the SSL UAT preference) will resize the window to match the string.
With this change, instead the hintLabel string is continuing on a new line to match currently configured window size

Scan our segment list (and the capture file) once per stream. Switch the
stream selection control to a QSpinBox. Add graph type selection
actions. The context menu + shortcuts should now be complete. Add the
intitial tcptrace graph. Only ACKs and RWINs so far. A bunch of other
updates and fixes.

Add get_tcp_stream_count() to the TCP dissector and modify
graph_segment_list_get() to allow matching based solely on a stream.
Use text instead of icons for the mouse click behavior buttons. Remove
their PNG resources since we aren't using them any more. Fix setting the
cursor in the graph widget.

Rename some methods. Add the ability to toggle time and sequence number
origins. Add more keyboard shortcuts. Comment out abs_secs abs_usecs in
the segment struct since it looks like we aren't using them. Make sure
we stay in the same TCP stream.

Show the time values in ms instead of s. Add a button and keyboard

GTK+: Fix what appears to be an off-by-one error in the MA period (21
segments instead of 20). Throw away our initial segment length instead
of subtracting it from the moving sum, which skews the sum.
Qt: Add the througput graph. Use bits/s for the throughput y axis. Let
the user switch between graph types. The dialog hangs when doing this. I
haven't been able to track down the cause. Remove some unused code.
Both: Tell the user that we're using a 20 segment moving average. Move
more routines to tap-tcp-stream.[ch].

QCustomPlot data sets are made up of keys (x axis by default) and values
(y axis). It looks like we can have multiple values for a given key
(i.e. we can show multiple sequence numbers for a given timestamp) but
QCPItemTracers can only be positioned by a key and not a key+value pair.
This makes our graph selection behavior a bit different compared to the
GTK+ version. We can only select one segment for a give timestamp but
our selection targets are much larger (the height of the graph).
Add a map for segment data so we don't have to iterate to find them. Use
UTF8_RIGHTWARDS_ARROW where appropriate. Set a window title. Tell the
user what will happen if he or she clicks. Disable graph selection.

Add the QCustomPlot widget. Thanks to Emanuel Eichhammer for granting a
license change. Move some common code from ui/gtk/tcp_graph.c to
ui/tap-tcp-stream.[ch]. Get rid of tcp_graph_selected_packet_enabled().
It was only used in the menu code and didn't match what we were doing
elsewhere.
Still quite a bit of work to do but it's a promising start.
