Minor notes snort-3.0.0-a1

[Y M <snort () outlook com>]

1. Difference in performance profiling configuration option when building snort with cmake vs. autotools:    cmake 
accepts enable-perfprofiling but not enable-perf-profiling    autotools accepts enable-perf-profiling but not 
enable-perfprofiling
2. When running snort, a fatal error may be generated:     FATAL: can't init /usr/local/snort/etc/snort.lua: 
/usr/local/snort/etc/snort.lua:22: module 'snort_config' not found:        no field package.preload['snort_config']     
   no file './snort_config.lua'    no file '/usr/local/share/luajit-2.0.3/snort_config.lua'        no file 
'/usr/local/share/lua/5.1/snort_config.lua'     no file '/usr/local/share/lua/5.1/snort_config/init.lua'        no file 
'./snort_config.so'     no file '/usr/local/lib/lua/5.1/snort_config.so'        no file 
'/usr/local/lib/lua/5.1/loadall.so'      Fatal Error, Quitting..
    snort_config.lua is not copied to /etc when installing snort. Manually copying snort_config.lua to /etc fixes the 
issue. 
3. Difference in dump_stats() when running with --shell and dump_stats() after running quit():        o")~
