Replace the Large File Support CMake stuff.
The existing stuff doesn't appear to work (I tried it on 32-bit Ubuntu 18.04, and it did *not* add any flags to the compilation, as it appeared not to conclude that they were necessary, even though they were). Pull in the stuff from libpcap, which *does* appear to work. (it does so in my 32-bit Ubuntu testing). This should fix #17301. While we're at it, fix cppcheck.sh so that it doesn't attempt to run cppcheck on files that have been deleted.pespin/rlcmac
