    tools: Portability fix for gpgparsemail.
    
    * tools/rfc822parse.c (my_stpcpy): Rename from stpcpy.

    When HAVE_STPCPY is not defined (no definition in libc), still,
    compiler may have definition as a built-in function (for some specific
    case like second argument is constant).  In that case, having stpcpy
    implementation with the same name but different signature ("static"
    qualifier) is not good.
