Differences re #define statements for autofoo vs cmake generated
config.h files on Linux.

Notes:
1. "Used"/"Not used" for the #define'd symbols as shown below is based
   upon a simple grep though all the Wireshark *.h, *.c, *.cpp source
   files.
2. The comparison between the config.h files was somewhat Q+D so there
   may very well be inaccuracies.
3. I've not done the further research to determine if the config.h
   differences for any of the "Used" #defines are significant
   (and unfortunately will not have the time to do so in the upcoming
   week).
4. I did remove a few instances of differences which I deemed not
       relevant; E,G., DATAFILE_DIR).

"-" = Defined only in autofoo config.h
"+" = Defined only In cmake config.h

======

#undefs which do not have a corresponding #define/#undef in
 the other config.h for Linux only.
Each instance may or may not be relevant; In some cases #defines
 would be generated on specific platforms as needed ?
 In other cases the symbols aren't used so the #undef is redundant.

"-" = #undef only in autofoo config.h
"+" = #undef only In cmake config.h
