Add an optional argument to extcap-version, which tells the utilities
the wireshark version and therefore allows them to handle different
versions differently.
If no version is provided, the utility has to assume it is dealing
with a Wireshark 2.x version (default behavior).

There's one mode you use if byte_mode is true, and another mode you use
if it's false. My head hurts when I try to pretend to be a top-down
parser for C and feed myself the existing expression, and Visual Studio
Code Analyzer says "are you sure that's what you had in mind?", so I'm
guessing the modes are:
byte mode: PIPE_TYPE_BYTE | PIPE_READMODE_BYTE | PIPE_WAIT
not byte mode: PIPE_TYPE_MESSAGE | PIPE_READMODE_MESSAGE | PIPE_WAIT
and am just using one test of byte_mode to choose between them.
Put the entire function under an #ifdef, so we can mark the byte_mode

--time-stamp-type <type>

Name choice mimics those used by tcpdump(1), which already supports this

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.

This patch reads out the stderr messages from an extcap
utility and displays it to an user. It was tested on Qt
but not on GTK, but should work their as well.
On Mac OS/X and Windows the child_watch does not behave
as it was intended. Therefore in extcap_cleanup, the callbacks
are called manually, if and only if, they have not been
called already.
The reason why it displays two error messages is, that
by the time the first one is being displayed, glib has not
returned from the spawned process on Linux yet. So there
is no way to add the stderr correctly, and putting a handler
to stderr into interface_opts will lead to memory errors,
cause then the code tries to access memory outside of its
protection.

The list should start with the native local interfaces, as returned by
pcap, so that we default to the interface pcap gives first, rather than
to whatever extcap interface happens to be at the beginning.
This also means that, if we're only calling extcap_interface_list() to
regenerate our internal data structures, we don't bother allocating -
and leaking! - a list of if_info structures.

overview of the possible rules can be found at:
http://doc.qt.io/qt-4.8/qregexp.html
If a required option is present, even the double-click on
the interface will first start the options dialog (Qt only)
Required fields are marked bold and put first in the dialog.
Additionally if validation failes (which it will if a required
field is kept empty, but also if a non-required textfield is
violating the defined regex), the label of the field is marked
with red.
