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.)

remove its selected status if it was selected

at the moment, an interface that was used for capturing before will
never be removed from the list of interfaces even if it becomes
unavailable as it remains in ifaces and will be re-added to all_ifaces
in scan_local_interfaces()

new helper function capture_opts_del_iface() to delete an entry from ifaces and

In Wireshark on Windows, create a console before doing so and destroy it

console-mode programs on Windows.

This should fix bug 8609 and still allow "wireshark -D" and "wireshark

Cast away some implicit 64-bit-to-32-bit conversion errors due to use of
strtol() and strtoul().

Change some data types to avoid those implicit conversion warnings.

When assigning a constant to a float, make sure the constant isn't a
double, by appending "f" to the constant.

Constify a bunch of variables, parameters, and return values to
eliminate warnings due to strings being given const qualifiers.  Cast
away those warnings in some cases where an API we don't control forces
us to do so.

Enable a bunch of additional warnings by default.  Note why at least
some of the other warnings aren't enabled.

randpkt.c and text2pcap.c are used to build programs, so they don't need
to be in EXTRA_DIST.

If the user specifies --enable-warnings-as-errors, add -Werror *even if
the user specified --enable-extra-gcc-flags; assume they know what
they're doing and are willing to have the compile fail due to the extra
GCC warnings being treated as errors.

Anders Broman 28474fe8ef From Mike Garratt:
Friendly Names for interfaces on Windows

Notes on the changes the patch covers:
* if_info_t struct: addition of friendly_name
* Dumpcap Interface list format changes:
  + Win32: "dumpcap -D" shows friendly_name in place of descript if known
  + All: machine interface "dumpcap -D -Z none" includes friendly_name in the
list in addition to the existing parameters
* interface_options struct: addition of console_display_name
  + When an interface name is displayed in a console, it will typically be the
console_display_name (instead of name). 
  + console_display_name is used as the basis of the autogenerated temp
filenames
  + console_display_name is typically set to the friendly_name if known,
otherwise it is set to the interface name
* Enhancements to capture_opts_add_iface_opt() (the function which process -i
options).
  + Can now specify the interface using its name and friendly_name
  + Interface name matching is case insenstive
  + Name matching first attempts exact matching, then falls back to prefix
matching
    (e.g. dumpcap -i local)
  + Validates interface names, instead of blindly sending them off to
winpcap/libpcap
  + Interface specification by number is still supported.
* capture_opts_trim_iface() has been refactored:
  + Instead of repeating a decent chunk of the cost in
capture_opts_add_iface_opt(), it calls capture_opts_trim_iface() to specify the
interface.
* introduction of capture_win_ifnames.[ch] (windows only code)
  + Implements static function GetInterfaceFriendlyNameFromDeviceGuid() - a
windows version independant function to convert an interface guid into its
friendly name.  Uses published api functions on windows vista and higher, but
falls back to unpublished API functions on older windows releases.
  + void get_windows_interface_friendlyname(/* IN */ char
*interface_devicename, /* OUT */char **interface_friendlyname); - extracts the
GUID from the interface_devicename, then uses
GetInterfaceFriendlyNameFromDeviceGuid() to do the resolution
* Auto temp filename generation:
  + Now uses wireshark_pcapng_* or  wireshark_pcap_* depending on file format
  + Basis temp filename format on console_display_name
  + Win32: if console_display_name is a windows interface guid, extracts
numbers from GUID here (instead of in interface option processing) 

GUI CHANGES:
* Dialog that displays when you click the "Manage Interfaces" button (within
Capture Options dialog) has been renamed from "Add new interfaces" to
"Interface Management"
* ui/gtk/capture_dlg.c: new_interfaces_w variable renamed to
interface_management_w
* Win32: Local Interfaces tab on Interface Management dialog, shows includes
friendly name as far left column
* Interface Management dialog defaults to larger size on win32 - so it fits
without resizing local interfaces tab
* Interface Management dialog now saves preferences when you click the apply
button (local hidden interfaces was not persisting across restarts)
* Tweaks: "Interface Details" dialog (Interface list->Capture Interfaces ->
Details):
  + "Friendly Name" renamed to "NDIS Friendly Name"
  + Added "OS Friendly Name" to the top of the list
* Win32: The "Capture Interfaces" dialog now shows the friendly name instead of
device guid
* Welcome screen:
  + The height of the interface list scrollbox dynamically adjusts & updates to
the number visible interfaces.
    Up to 10 interfaces can be listed without a scroll bar, the minimum height
is for 2 interfaces. 
  + Win32: now shows just the Friendly Name if known - in place of
"Interfacename_Guid:(Description)"
