Ahmad Fatoum aca55a29f7 Add hardware timestamping support
pcap provides a pcap_set_tstamp_type function, which can be used to request
hardware timestamps from a supporting kernel.

This patch adds support for aforementioned function as well as two new
command line options to dumpcap, wireshark and tshark:

    --list-time-stamp-types
                             List time stamp types supported for the interface
    --time-stamp-type <type>
                             Change the interface's timestamp method

Name choice mimics those used by tcpdump(1), which already supports this
feature. However, unlike tcpdump, we provide both options unconditionally.
If Wireshark was configured without pcap_set_tstamp_type being available,
--list-time-stamp-types reports an empty list.

Guy Harris 60f87ca919 Put the extcap interfaces at the *end* of the interface list.
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.

Preferences, search for Protocol "IEEE 802.11" (because it has radio
buttons), then close everything again.

Many fixes are trivial, but the various recent_read_* functions in
recent.c were changed to return a boolean such that the result can
always be checked even if errno==0.

QButtonGroup leak was hinted by Clang Static Analyzer, all other
memleaks were found using ASAN/LSan.

Roland Knall bed29af46d Extcap Capture Interface
Extcap is a plugin interface, which allows for the usage
 of external capture interfaces via pipes using a predefined
 configuration language which results in a graphical gui.

 This implementation seeks for a generic implementation,
 which results in a seamless integration with the current
 system, and does add all external interfaces as simple
 interfaces.

 Windows Note: Due to limitations with GTK and Windows,
 a gspawn-winXX-helper.exe, respective gspawn-winXX-helper-console.exe
 is needed, which is part of any GTK windows installation.

 The default installation directory from the build is an extcap
 subdirectory underneath the run directory. The folder used by
 extcap may be viewed in the folders tab of the about dialog.

 The default installation directory for extcap plugins with
 a pre-build or installer version of wireshark is the extcap
 subdirectory underneath the main wireshark directory.

 For more information see:

  http://youtu.be/Nn84T506SwU
  bug #9009

 Also take a look in doc/extcap_example.py for a Python-example
 and in extcap.pod for the arguments grammer.

 Todo:
   - Integrate with Qt - currently no GUI is generated, but
     the interfaces are still usable

Guy Harris f6ce0cdacd Get rid of NO_INTERFACES_FOUND - it's not an error.
It just means "pcap didn't give me any interfaces, and didn't report an
error".  Hopefully, in the future, there will be pcap APIs that
distinguish between the (admittedly unlikely, these days) case of "there
really *are* no interfaces on which *anybody* can capture" and "you
don't have sufficient permission to capture", and we can report the
latter as an error.  (Given that pcap supports more than just "regular
interfaces", though, there are cases where you don't have permission to
capture on those but you have permission to capture raw USB traffic, for
example, so perhaps what's really needed is per-interface indications of
permissions.)

Guy Harris 4261109e1e Don't return an error string for NO_INTERFACES_FOUND.
Most callers of capture_interface_list() don't expect an error string
for NO_INTERFACES_FOUND, because that's not really an error, it's just a
statement of face (and perhaps an error of 0 should be returned), so
they don't bother freeing the error string, causing a leak.

Instead, have the one place that *did* expect it to return an error
string just put "No interfaces found" itself.

Also, have that place not check for an error string if interfaces *were*
found, as no error code or string is returned in that case.
