Rename ext_menubar to a more appropriate plugin_if. External menus can be implemented by plugins to present additional menus for deep-packet analysis. One side-effect of such menus being implemented as plugins is, that they are being executed in different threads and therefore can only use limited access to the main GUI. Also, there is no safe cross-gui (GTK and Qt) way for many features. This patch implements a first functionality, by which a plugin implemented using ext_menubar can apply a display filter to the main view. For now the implementation supports filtering, as well as saving a preference.

* An API for Wireshark plugins
|
|
*
|
|
* This enables wireshark dissectors, especially those implemented by plugins
|
|
* to register menubar entries, which then will call a pre-defined callback
|
|
* function for the dissector or plugin.
|
|
*
|
|
* Also it implements additional methods, which allow plugins to interoperate
|
|
* with the main GUI.
