Restore the ability in tshark -e to filter based on column titles,
at least for the seven default columns. Internally alias the fields
based on their titles to the column type based fields, e.g.
"_ws.col.Info" to "_ws.col.info"
This may be removed in the future, but is useful to have as there
are tools and scripts that use the old beahvior (and there are
supports versions, 3.6.x and 4.0.x, that only support the old
behavior.)
Make the text of each registered column a FT_STRING field that can be
filtered, prefixed with _ws.col - these work in display filters, filters
in taps, coloring rules, Wireshark read filters, and in the -Y, -R, -e,
and -j options to tshark. Use them as the default "Apply as Filter" value
for the columns that aren't handled by anything else currently.
Because only the columns formats that actually correspond to columns
get filled in (invisible columns work), register and deregister the
fields when the columns change.
Use the lower case version of the rest of the COL_* define for each
column as the field name.
This adds a number of conditions to "when are the columns needed",
including when the main display filter or any filter on a tap is
using one of these fields.
Custom columns are currently not implemented. For custom columns, the
tree then has to be further primed with any fields used by the custom
columns as well. (Perhaps that should happen in epan_dissect_run() -
are there any cases where we construct the columns and don't want to
prime with any field that custom columns contains? Possibly in taps
that we know only use build in columns.)
Thus, for performance reasons, you're better off matching an ordinary
field if possible; it takes extra time to generate the columns and many
of them are numeric types. (Note that you can always convert a non-string
field to a string field if you want regex matching, consult the
*wireshark-filter(4)* man page.) It does save a bit on typing (especially
for a multifield custom column) and remembering the column title might
be easier in some cases.
The columns are set before the color filters, which means that you
can have a color filter that depends on a built-in column like Info or
Protocol.
Remove the special handling for the -e option to tshark. Note that
the behavior is a little different now, because fixed field names
are used instead of the titles (using the titles allowed illegal
filter names, because it wasn't going through the filter engine.)
For default names, this means that they're no longer capitalized,
so "_ws.col.info" instead of "_ws.col.Info" - hopefully a small
price in exchange for the filters working everywhere.
The output format for -T fields remains the same; all that special
handling is removed (except for remembering if someone asked for
a column field to know that columns should be constructed.)
They're also set before the postdissectors, so postdissectors can
have access.
Anything that depends on whether a packet and previous packets are
displayed (COL_DELTA_TIME_DIS or COL_CUMULATIVE_BYTES) doesn't work
the way most people expect, so don't register fields for those.
(The same is already true of color filters that use those, along with
color filters that use the color filter fields.)
Fix#16576. Fix#17971. Fix#4684. Fix#13491. Fix#13941.
Move the deprecated column check functions from the prefs
file to the (Wireshark internal use) column files. Make
them public so that the recent file checking can use them.
This keeps column handling in one place.
Make the recent file column width checking able to convert
a deprecated column to a custom column the same as the main
prefs file.
Move all the declarations of routines that are internal and
not for use by dissectors from column-utils.h column-info.h
Move the column max length defines into column-utils.h because
dissectors might need that
Since packet.h already includes column-utils.h, dissectors don't
need to include column-utils.h anymore.
Remove or downgrade a few other column header includes that are
unnecessary.
Add a function to get the column text of the nth column, taking
into account whether the column is resolved or unresolved. Use
this function in the GUI, as well as in tshark, when writing
PSML, exporting dissection to PSML, etc., instead of accessing
col_data directly.
This removes the direct accesses of col_data from outside
column.c and column-utils.c
Fix#18168.
GTK already has it, but Qt forgot about it, so multi-field custom column
works ok if previously saved in GTK-shark. Invalid validation prevent from
modifying and saving multi-field custom column in Qt version.
While at it, rename "custom field" to "custom fields" to ensure
we think about multi-field custom column.

"column.format" in a later argument, make sure we mark the appropriate
existing columns as hidden.
As part of cleaning up the infrastructure for doing this, store the COL_
code for a column in a fmt_data structure rather than a pointer to the
raw column format string; this simplifies some code.
Have a routine to return whether a column is visible, not hidden, as
it's used to set a "visible" flag.
