SenseApiLib, SenseApiDesc improvements, new Sense API Mgmt Lib Ops role

SenseApiDesc:
* Use a number count for num exported implexor APIs instead of
  NULL-terminated list.
* Add sanity checker functions for structs.

SenseApiLib:
* Invoke the new sanity checkers on new Lib objects.
* SenseApiDesc is now a member object instead of being
  pointed to.

SenseApiManager:
* loadSenseApiLib now calls the SenseApiDesc getter function.
* loadSenseApiLib now fills out the SenseApiLib class object.

New Sense API Mgmt Sub-API:

This sub-api (metalanguage, some might call it) is used to initialize
the lib's connection to the provider. After this call, the lib should
be ready to attach new devices to its provider on behalf of Hk.
