    User on OpenMPI list wanted to create a 259 character file.  shared file
    pointer name construction used the magic '256' value to construct a full
    path to the hidden shared file pointer file.  PATH_MAX already exists
    for this purpose, so use it.
    
    While there, found a few spots checking/setting PATH_MAX, so do that in
    one place
    
    Closes #2212
