While looking into possible fixes for bug 3239, I discovered that the
preference API (and the GUI screens that can be created from it) is written
fairly generically, but that only the "protocols" can take advantage of it.

This first patch allows the Statistics and "Protocol" (parent) screens to be
populated through the generic preferences API that already exists.  The current
filter field names were more specific than the categories provided through the
GUI, so I'm not sure how backwards the solution is.  Not sure how big an issue
that is.

I kept the preferences structure (e_pref) together for "backwards code
compatibility" and to minimize the number of global variables needed for
preferences, although the hope was that some members could be moved out to be
self-contained within an individual source module. 

If this design is acceptable, I will continue and provide more patches of the
other GUI preferences screens.  I may not be able to include the User Interface
and its sub screens, but everything else appears that it will fit in with the
"preferences API". 

In addition to the patch, the following files can be removed as they are no
longer needed (because they can be "generated" with the generic preferences
API):
\wireshark\ui\gtk\prefs_protocols.c
\wireshark\ui\gtk\prefs_protocols.h
\wireshark\ui\gtk\prefs_taps.c
\wireshark\ui\gtk\prefs_taps.h
