Type validating smr protected pointer accessors.

This API is intended to provide some measure of safety with SMR
protected pointers.  A struct wrapper provides type checking and
a guarantee that all access is mediated by the API unless abused.  All
modifying functions take an assert as an argument to guarantee that
the required synchronization is present.
