slicc: added MOESI_CMP_directory, DMA SequencerMsg, parameterized controllers

This changeset contains a lot of different changes that are too
mingled to separate.  They are:

1.  Added MOESI_CMP_directory

I made the changes necessary to bring back MOESI_CMP_directory,
including adding a DMA controller.  I got rid of MOESI_CMP_directory_m
and made MOESI_CMP_directory use a memory controller. Added a new
configuration for two level protocols in general, and
MOESI_CMP_directory in particular.

2.  DMA Sequencer uses a generic SequencerMsg

I will eventually make the cache Sequencer use this type as well.  It
doesn't contain an offset field, just a physical address and a length.
MI_example has been updated to deal with this.

3. Parameterized Controllers

SLICC controllers can now take custom parameters to use for mapping,
latencies, etc.  Currently, only int parameters are supported.
