This patch updates Ruby configuration scripts to use the functions
defined in the RubySequencer python object to connect to cpu ports.
Only the protocol-agnostic scripts were updated. Scripts that assume
a specific protocol (e.g. configs/example/apu_se.py, gpu tests, etc)
and scripts in which the obj connected to the RubySequencer is not a
BaseCPU (e.g. the tests scripts) were not changed as they require a
non-standard port wireup.

Calls to queueMemoryRead and queueMemoryWrite do not consider the size
of the queue between ruby directories and DRAMCtrl which causes infinite
buffering in the queued port between the two. This adds a MessageBuffer
in between which uses enqueues in SLICC and is therefore size checked
before any SLICC transaction pushing to the buffer can occur, removing
the infinite buffering between the two.

Adds a new config script to configure the MI_example protocol. This script
closely follows the script used for MSI, but instead supports the
MI_example protocol. This script works with the simple_ruby runscript and
can be included instead of msi_caches.
