    afsio: switch BreakUpPath to strdup
    
    The current version of BreakUpPath is slightly broken, since
    commit 4e68282e26b0c4569d25d076d54274f0da47a691 -- it has two
    output parameters but takes only one length parameter for the
    size of the output buffers passed in.  The callers ended up using
    the shorter of the buffer lengths in question, so there is not
    a risk of a buffer overrun, but long paths would not be properly
    handled.
    
    There is not really any need to pass in a length at all, since
    what is going on is conceptually strdup, and there is no real
    need to use strlcpy at all.  Make the change from strlcpy to
    str(n)dup, and adjust callers to free the outputs as appropriate.
    
    While here, convert writeFile() to use goto and a cleanup handler
    to avoid leaks.
