Peter Wu 3aee917058 wiretap: remove unused code, drop number_of_interfaces
While investigating an ASAN issue (fixed in
commit dcdd076ab0), I got greatly confused
by three different types having the same "interface_data" field name:

 * pcapng_t *pn stores an array of interface_data_t objects.
 * wtap *wth stores an array of wtapng_if_descr_t objects.
 * pcapng_dump_t should store an array of interface_data_t objects.

pcapng_dump_t and friends are unused since
commit c7f1a431d2, so drop it.

To fix the confusion, rename the interface_data_t type to
interface_info_t type and use the local variable "iface_info"
everywhere. Rename interface_data of pcapng_t to "interfaces" and
add a comment what this exactly means (interfaces listed in the capture
file).

Drop the number_of_interfaces field for interfaces as the array
length is already available from GArray. Now interface_data is always
initialized for wth (which also gets copied to idb).

s/int/guint/g and replace cast at some places.

There are no regressions for the in-tree test suite.

Michael Mann 1abeb277f5 Refactor Wiretap
Start of refactoring Wiretap and breaking structures down into "generally useful fields for dissection" and "capture specific". Since this in intended as a "base" for Wiretap and Filetap, the "wft" prefix is used for "common" functionality.

The "architectural" changes can be found in cfile.h, wtap.h, wtap-int.h and (new file) wftap-int.h. Most of the other (painstaking) changes were really just the result of compiling those new architecture changes.

Peter Wu dfb92dfd67 Fix crash when switching profiles
rescan_packets() starts a new dissection session by free'ing the
previous state and creating a new one. A reference to the old session
was not updated though.

This is the only place where epan is overwritten. After init, col_init
will at some point initialize cf->cinfo.epan with a cf->epan.

Gerald Combs a5cb72fe9e Add a Qt I/O Graph dialog.
For each graph you can set:
- Its visibility
- A name
- A display filter
- Color, from a fixed list
- Plot style: Line, Impulse, Bar, Stacked Bar, Dot, Square, Diamond
- Basic Y Axes (packets/s, bytes/s, bits/s)
- Computed Y Axes (SUM, MIN, AVG, MAX)
- Smoothing

You can pan and zoom using the mouse and keyboard. Clicking on a graph
selects the last packet for that interval. If all graphs have the same Y
axis a single label is shown, otherwise a legend is shown.

The time scale (X axis) can be toggled between relative seconds and the
time of day.

Graphs can be saved as PDF, PNG, BMP, and JPEG. Settings are "sticky"
via the io_graphs UAT.

To do:
- Minimize graph drawing delays.
- Figure out why smoothing differs from GTK+
- Everything else at the top of io_graph_dialog.cpp
- Fix empty resets.

A fair amount of code was copied from TCPStreamDialog. We might want to
subclass QCustomPlot and place the shared code there.

Move common syntax checking to SyntaxLineEdit.

Move some common code from ui/gtk/io_stat.c to ui/io_graph_item.[ch] and
use it in both GTK+ and Qt.

Make the io_graph_item_t array allocation in io_stat.c static. The
behavior should be identical and this gives us additional compile-time
checks.

This fixes part-1 of bug9931: the uninitialized use of a wtap_pkthdr
struct. The second part of the bug deals with dissectors calling
the Ethernet dissector for ecnapsulated Ethernet packets but using
the wrong dissector handle to do so. That's unrelated to the issue this
commit addresses, so I'm splitting them up.

Hadriel Kaplan d1873dbcc8 Fix Bug 9903: 'Clicking reload-file ignores selected file format reader'
There's a relatively new feature in 1.11.3 to select a specific file format
reader, instead of relying on magics or heuristics. If you select a file
reader and open a file, open it, and then click the reload-file button or go
to View->Reload or press the ctrl-R keymap, the file is reloaded but using the
magic/heuristics again instead of the file format reader you previously chose.
Likewise, the Lua relaod() function has the same issue (which is how I found
this problem).

I have tested this change by hand, using a Lua script, but I didn't add it
to the testsuite because I need another change for my test script to work
correctly. (an enhancement rather than a bug fix, which I'll submit separately)

Christopher Kilgour 7b13a3b0f6 Allow pcapng interface options to be available to dissectors.
Interface options[1], and more generally pcapng options[2], are useful
information that can provide improved dissector output.

Prior to this change, only certain pcapng interface options were interpreted
and made available to dissectors, e.g. the interface name or description.
This change augments the situation by providing epan_get_interface_option( ),
which returns an array of byte arrays if the option code exists
(otherwise NULL).  Each element of the array is a byte buffer containing
the raw data of the option.  An array-of-buffers is used because pcapng
allows for multiple instances of the same option to be present in the file.
All interface options found in a pcapng file are thus made available to the
dissector.

The implementation also provides infrastructure to collect options from
other pcapng blocks such as the section header.  Currently these options
are discarded, but could be retained in the future to support more features.
