Currently, this is only used to determine whether a protocol tree needs
to be built on the first pass or not - if there are postdissectors that
need fields, it does - but eventually we should be able to use it to
prime the dissection to deliver those fields in cases where we don't
need the *entire* protocol tree (rather than using a hack such as
cooking up a fake tap with a fake filter to do that).

This patch introduces the frame.interface_description field.
While testing this new functionality it became obvious that we have
a non-optimal interaction between the existing cfile.c's
cap_file_get_interface_name(), the recently added frame.interface_name
field and this new frame.interface_description field.
The string returned from cap_file_get_interface_name() may in fact
come from one of three different sources: the idb's interface name
(if it exists) or the idb's interface description (if that exists)
or a default text of "unknown". The string ultimately becomes the
rame.interface_name whether or not the idb had an interface name
option to begin with. This behavior does not allow one to test for
the simple presence of frame.interface_name. The new peer function
cap_file_get_interface_description() added by this patch returns
NULL instead of "unknown" if the idb does not have an interface
description. Should cap_file_get_interface_name() be similarly
modified to return NULL if the idb does not have an interface name?

This patch introduces new APIs to allow dissectors to have a preference for
a (TCP) port, but the underlying data is actually part of Decode As functionality.
For now the APIs are intentionally separate from the regular APIs that register a
dissector within a dissector table. It may be possible to eventually combine the
two so that all dissectors that register with a dissector table have an opportunity
to "automatically" have a preference to adjust the "table value" through the
preferences dialog.
The tcp.port dissector table was used as the guinea pig. This will eventually be
expanded to other dissector tables as well (most notably UDP ports). Some
dissectors that "shared" a TCP/UDP port preference were also converted. It also
removed the need for some preference callback functions (mostly when the callback
function was the proto_reg_handoff function) so there is cleanup around that.
Dissectors that has a port preference whose default was 0 were switched to using
the dissector_add_for_decode_as_with_preference API rather than dissector_add_uint_with_preference
Also added comments for TCP ports used that aren't IANA registered.

In commit v2.3.0rc0-117-g485bc45 (backported to v2.2.0rc0-44-g66721ca),
extcap_prefs_dynamic_vals and extcap_cleanup were added in an attempt to
address dangling pointers.
Unfortunately it is not sufficient:
- A pointer to the preference value is stored in extcap_arg and passed
to the prefs API, but this extcap_arg structure can become invalid
which result in use-after-free whenever the preference is accessed.
- On exit, a use-after-free occurs in prefs_cleanup when the preference
value is being checked.
As the preference subsystem actually manages the memory for the string
value and consumers should only provide a pointer where the value can be
stored, convert the char* field in extcap to char**. This has as
additional benefit that values are not limited to 256 bytes anymore.
extcap_cleanup is moved after epan_cleanup to ensure that prefs_cleanup
does not operate on dangling pointers.
Crash is reproducible under ASAN with: tshark -i randpkt

This patch introduces the "-U tap_name[,filter]" tshark option and
is similar to the "Export PDUs as file" option in Wireshark.
Wireshark implements this feature by reopening a capture file, applying
a tap and finally opening the temporary file. Since tshark knows
in advance that a PDU export is needed, it can optimize by not creating
the temporary file and perform the export at the first opportunity.
This patch splits the opening/tapping functionality from error reporting
since tshark does not need a temp file and has no dialogs.
The capture file comment is now specified explicitly as there is no
"current file" anymore if the tap is running without active file.
TODO:
- Review whether it is acceptable to overwrite save_file in tshark.
- Add documentation (tshark manpage).

This was inspired by https://code.wireshark.org/review/9729/, but takes it in a different direction where all options are put into an array, regardless of whether they are "standard" or "custom". It should be easier to add "custom" options in this design. Some, but not all blocks have been converted.
Descriptions of some of the block options have been moved from wtap.h to pcapng.h as it seems to be the one that implements the description of the blocks.
Also what could be added/refactored is registering block behavior.

The "-Wwrite-strings" flag produces nuisance warnings. These warnings are
not useful, they're impossible to fix in a sane way and therefore are being
handled with casts of static strings to (char *).
This just moves the warning to [-Wcast-qual] and a compiler pragma is
in turn required (and used) to squelch that warning.
Remove the Wwrite-strings warning. Let that responsibility fall on the
programmer (as is done by casting).
