WSUG: Convert the "User Interface" chapter to AsciiDoc.

Add the "asciidoc.conf" compatibility configuration file from
Asciidoctor. Although we don't use Asciidoctor it gives us macros that
keep us from losing some useful DocBook elements. Update various CMake
files to support multiple AsciiDoc configuration files.

Leave most of the content intact for now. Hopefully the other chapters
aren't as laden with markup.

+
+== User Interface
+
+[[ChUseIntroductionSection]]
+
+=== Introduction
+
+By now you have installed Wireshark and are most likely keen to get started
+capturing your first packets. In the next chapters we will explore:
+
+* How the Wireshark user interface works
+* How to capture packets in Wireshark
+* How to view packets in Wireshark
+* How to filter packets in Wireshark
+* ... and many other things!
+
+[[ChUseStartSection]]
+
+=== Start Wireshark
+
+You can start Wireshark from your shell or window manager.
+
+[TIP]
+.Power user tip
+====
+When starting Wireshark it's possible to specify optional settings using the
+command line. See <<ChCustCommandLine>> for details.
+====
+
+In the following chapters a lot of screenshots from Wireshark will be shown. As
+Wireshark runs on many different platforms with many different window managers,
+different styles applied and there are different versions of the underlying GUI
+toolkit used, your screen might look different from the provided screenshots.
+But as there are no real differences in functionality these screenshots should
+still be well understandable.
+
+[[ChUseMainWindowSection]]
+
+=== The Main window
+
+Let's look at Wireshark's user interface. <<ChUseFig01>> shows Wireshark as you
+would usually see it after some packets are captured or loaded (how to do this
+will be described later).
+
+[[ChUseFig01]]
+.The Main window
+image::wsug_graphics/ws-main.png[]
+
+Wireshark's main window consists of parts that are commonly known from many
+other GUI programs.
+
+. The _menu_ (see <<ChUseMenuSection>>) is used to start actions.
+. The _main toolbar_ (see <<ChUseMainToolbarSection>>) provides quick access to
+  frequently used items from the menu.
+. The _filter toolbar_ (see <<ChUseFilterToolbarSection>>) provides a way to
+  directly manipulate the currently used display filter (see
+  <<ChWorkDisplayFilterSection>>).
+. The _packet list pane_ (see <<ChUsePacketListPaneSection>>) displays a summary
+  of each packet captured. By clicking on packets in this pane you control what is
+  displayed in the other two panes.
+. The _packet details pane_ (see <<ChUsePacketDetailsPaneSection>>) displays the
+  packet selected in the packet list pane in more detail.
+. The _packet bytes pane_ (see <<ChUsePacketBytesPaneSection>>) displays the
+  data from the packet selected in the packet list pane, and highlights the field
+  selected in the packet details pane.
+. The _statusbar_ (see <<ChUseStatusbarSection>>) shows some detailed
+  information about the current program state and the captured data.
+
+[TIP]
+====
+The layout of the main window can be customized by changing preference settings.
+See <<ChCustPreferencesSection>> for details!
+====
+
+[[ChUseMainWindowNavSection]]
+
+==== Main Window Navigation
+
+Packet list and detail navigation can be done entirely from the keyboard.
+<<ChUseTabNav>> shows a list of keystrokes that will let you quickly move around
+a capture file. See <<ChUseTabGo>> for additional navigation keystrokes.
+
+[[ChUseTabNav]]
+.Keyboard Navigation
+[options="header"]
+|===============
+|Accelerator               |Description
+|kbd:[Tab], kbd:[Shift+Tab]| Move between screen elements, e.g. from the toolbars to the packet list to the packet detail.
+|kbd:[Down]                | Move to the next packet or detail item.
+|kbd:[Up]                  |Move to the previous packet or detail item.
+|kbd:[Ctrl+Down], kbd:[F8] |Move to the next packet, even if the packet list isn't focused.
+|kbd:[Ctrl+Up], kbd:[F7]   |Move to the previous packet, even if the packet list isn't focused.
+|kbd:[Ctrl+.]              |Move to the next packet of the conversation (TCP, UDP or IP)
+|kbd:[Ctrl+&#x2c;]         |Move to the previous packet of the conversation (TCP, UDP or IP)
+|kbd:[Left]                |In the packet detail, closes the selected tree item. If it's already closed, jumps to the parent node.

+|kbd:[Return], kbd:[Enter] |In the packet detail, toggles the selected tree item.
+|===============
+
+Additionally, typing anywhere in the main window will start filling in a display filter.
+
+[[ChUseMenuSection]]
+
+=== The Menu
+
+Wireshark's main menu is located either at the top of the main window (Windows,
+Linux) or at the top of your main screen (OS X). An example is shown in
+<<ChUseWiresharkMenu>>.
+
+[NOTE]
+====
+Some menu items will be disabled (greyed out( if the corresponding feature isn't
+available. For example, you cannot save a capture file if you haven't captured
+or loaded any packets.
+====

+
+[[ChUsePacketListPaneSection]]
+
+=== The ``Packet List'' pane
+
+The packet list pane displays all the packets in the current capture file.
+
+[[ChUseWiresharkListPane]]
+.The ``Packet List'' pane
+image::wsug_graphics/ws-list-pane.png[]
+
+Each line in the packet list corresponds to one packet in the capture file. If
+you select a line in this pane, more details will be displayed in the ``Packet
+Details'' and ``Packet Bytes'' panes.
+
+While dissecting a packet, Wireshark will place information from the protocol
+dissectors into the columns. As higher level protocols might overwrite
+information from lower levels, you will typically see the information from the
+highest possible level only.
+
+For example, let's look at a packet containing TCP inside IP inside an Ethernet
+packet. The Ethernet dissector will write its data (such as the Ethernet
+addresses), the IP dissector will overwrite this by its own (such as the IP
+addresses), the TCP dissector will overwrite the IP information, and so on.
+
+There are a lot of different columns available. Which columns are displayed can
+be selected by preference settings, see <<ChCustPreferencesSection>>.
+
+The default columns will show:
+
+* button:[No.] The number of the packet in the capture file. This number won't
+  change, even if a display filter is used.
+
+* button:[Time] The timestamp of the packet. The presentation format of this
+  timestamp can be changed, see <<ChWorkTimeFormatsSection>>.
+
+* button:[Source] The address where this packet is coming from.
+
+* button:[Destination] The address where this packet is going to.
+
+* button:[Protocol] The protocol name in a short (perhaps abbreviated) version.
+
+* button:[Info] Additional information about the packet content.
+
+There is a context menu (right mouse click) available, see details in
+<<ChWorkPacketListPanePopUpMenu>>.
+
+[[ChUsePacketDetailsPaneSection]]
+
+=== The ``Packet Details'' pane
+
+The packet details pane shows the current packet (selected in the ``Packet List''
+pane) in a more detailed form.
+
+[[ChUseWiresharkDetailsPane]]
+
+.The ``Packet Details'' pane
+image::wsug_graphics/ws-details-pane.png[]
+
+This pane shows the protocols and protocol fields of the packet selected in the
+``Packet List'' pane. The protocols and fields of the packet are displayed using a
+tree, which can be expanded and collapsed.
+
+There is a context menu (right mouse click) available, see details in
+<<ChWorkPacketDetailsPanePopUpMenu>>.
+
+Some protocol fields are specially displayed.
+
+* *Generated fields* Wireshark itself will generate additional protocol fields
+  which are surrounded by brackets. The information in these fields is derived
+  from the known context to other packets in the capture file. For example,
+  Wireshark is doing a sequence/acknowledge analysis of each TCP stream, which
+  is displayed in the [SEQ/ACK analysis] fields of the TCP protocol.
+
+* *Links* If Wireshark detected a relationship to another packet in the capture
+  file, it will generate a link to that packet. Links are underlined and
+  displayed in blue. If double-clicked, Wireshark jumps to the corresponding
+  packet.
+
+[[ChUsePacketBytesPaneSection]]
+
+=== The ``Packet Bytes'' pane
+
+The packet bytes pane shows the data of the current packet (selected in the
+``Packet List'' pane) in a hexdump style.
+
+[[ChUseWiresharkBytesPane]]
+
+.The ``Packet Bytes'' pane
+image::wsug_graphics/ws-bytes-pane.png[]
+
+As usual for a hexdump, the left side shows the offset in the packet data, in
+the middle the packet data is shown in a hexadecimal representation and on the
+right the corresponding ASCII characters (or . if not appropriate) are
+displayed.
+
+Depending on the packet data, sometimes more than one page is available, e.g.
+when Wireshark has reassembled some packets into a single chunk of data, see
+<<ChAdvReassemblySection>>. In this case there are some additional tabs shown at
+the bottom of the pane to let you select the page you want to see.
+
+[[ChUseWiresharkBytesPaneTabs]]
+.The ``Packet Bytes'' pane with tabs
+image::wsug_graphics/ws-bytes-pane-tabs.png[]
+
+[NOTE]
+====
+The additional pages might contain data picked from multiple packets.
+====
+
+
+The context menu (right mouse click) of the tab labels will show a list of all
+available pages. This can be helpful if the size in the pane is too small for
+all the tab labels.
+
+[[ChUseStatusbarSection]]
+
+=== The Statusbar
+
+The statusbar displays informational messages.
+
+In general, the left side will show context related information, the middle part
