    Add more 'fall through' switch comments
    
    Commit a455452d (LINUX 5.3: Add comments for fallthrough switch cases)
    added the special /* fall through */ comment to various switch/case
    blocks, in order to avoid implicit-fallthrough warnings from causing
    the build to fail when building the Linux kernel module.
    
    In this commit, add additional /* fall through */ comments to the rest
    of the tree where falling through is intentional. Add a "break;" in one
    place in dumptool.c where falling through seems like a mistake, and flag
    certain functions as AFS_NORETURN to avoid needing to explicitly break
    or fallthrough.
    
    Check for the availability of the -Wimplicit-fallthrough compiler flag
    and use it when --enable-checking is set, to prevent additional cases
    from creeping into the tree.
    
    Note: the -Wimplicit-fallthrough compiler flag was added in gcc 7.
