Presently, a reference to the chaincode support is carried to the
inproccontroller as a value on the context, which is a really odd/wrong
thing to do.  This CR makes the dependency explicit by adding it as a
member of the inproccontroller structs, setting it as soon as the
chaincode support is available.

Ideally, the creation of the inproccontroller would be atomic, but, such
are our wiring woes, that the chaincode support can only be set after
the initial construction.
