    don't allocate serial_ops
    
    Now that struct serial_ops is const everywhere, we can easily turn the
    instances into globals.  This patch implements this idea.
    
    On the one hand I think this is nicer since it makes a bit more data
    readonly and slightly reduces allocations.  On the other hand it
    reduces readability somewhat.
    
    If the readability is a concern to anyone I was thinking I could write
    a macro that conditionally uses GCC's designated initializer
    extension.
    
    Tested by rebuilding on x86-64 Fedora 18, both natively and using the
    mingw cross tools.

    make serial_ops const
    
    I noticed that the serial_ops vtable is not const, but really it ought
    to be.
    
    This patch constifies it, removing the only mutable field in the
    process.
    
    Tested by rebuilding on x86-64 Fedora 18, both natively and using the
    mingw cross tools.
