Guy Harris cfcbb28671 Clean up ftype-conversion and dfilter error message string handling.
Have dfilter_compile() take an additional gchar ** argument, pointing to
a gchar * item that, on error, gets set to point to a g_malloc()ed error
string.  That removes one bit of global state from the display filter
parser, and doesn't impose a fixed limit on the error message strings.

Have fvalue_from_string() and fvalue_from_unparsed() take a gchar **
argument, pointer to a gchar * item, rather than an error-reporting
function, and set the gchar * item to point to a g_malloc()ed error
string on an error.

Allow either gchar ** argument to be null; if the argument is null, no
error message is allocated or provided.

Guy Harris 318cf8a678 Add support for dissecting non-packet records.
Add a dissector table indexed by the file type, and, for the
file-type-specific records, have the frame dissector skip the usual
pseudo-header processing, as the pseudo-header has a file-type-specific
record subtype in it, and call the dissector for that file type's
records.

Guy Harris 6db77b000f Allow wtap_read() and wtap_seek_read() to return records other than packets.
Add a "record type" field to "struct wtap_pkthdr"; currently, it can be
REC_TYPE_PACKET, for a record containing a packet, or
REC_TYPE_FILE_TYPE_SPECIFIC, for records containing file-type-specific
data.

Modify code that reads packets to be able to handle non-packet records,
even if that just means ignoring them.

Rename some routines to indicate that they handle more than just
packets.

We don't yet have any libwiretap code that supplies records other than
REC_TYPE_PACKET or that supporting writing records other than
REC_TYPE_PACKET, or any code to support plugins for handling
REC_TYPE_FILE_TYPE_SPECIFIC records; this is just the first step for bug
8590.

Guy Harris a344c9736e Revert "Allow wtap_read() and wtap_seek_read() to return non-packet records."
This reverts commit c0c480d08c.

A better way to do this is to have the record type be part of struct wtap_pkthdr; that keeps the metadata for the record together and requires fewer API changes.  That is in-progress.

Guy Harris c0c480d08c Allow wtap_read() and wtap_seek_read() to return non-packet records.
This is the first step towards implementing the mechanisms requestd in
bug 8590; currently, we don't return any records other than packet
records from libwiretap, and just ignore non-packet records in the rest
of Wireshark, but this at least gets the ball rolling.

This reverts commit 1abeb277f5.

This isn't building, and looks as if it requires significant work to fix.

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.

Gerald Combs 07c3d057b8 Add previous/next stream navigation to the TCP stream graph dialog.
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.

we stay in the same TCP stream.

Gerald Combs 03fd39d7f0 Throughput graph updates.
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].

Add the QCustomPlot widget. Thanks to Emanuel Eichhammer for granting a

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.
