Add -Werror to acceptance builds for C and CPP (#4369)
Use platform.local.txt to add -Werror to GCC for the build of all code. Any warnings on a submitted patch will cause an error. Several examples and libraries had warnings/errors (missing returns on functions, types, etc.). Clean those up with this commit as well.
