Finalized DDS Reader interface. Implemented read/take,
read_next_sample/take_next_sample, read_instance/take_instance,
read_next_instance/take_next_instance operations.
Instance Get operations were made generic to allow returning 2 variants
of instance data.
It was decided to connect the DDS Endpoint directly to the RTPS
Endpoint. The history_cache Entity will be converted to a generic
History Cache acording to the RTPS Specification.
Because of consistency requirements the implementation was changed to a
single process/single port RAM design.
This should fully (blindly) implement the RTPS Reader side of the DDS
Entity.
Redefined Sample Memory Format. The design decision was made to handle
most (if not all) of the DDS QOS inside the History Cache, which allows
storing needed information in a more efiicient way.
A (dual port) Instance Memory was added into the HC, to support the QOS
operations.
This commit only implements the A side processes for the READER case.
RESOURCE_LIMITS_QOS, TIME_BASED_FILTER_QOS, and HISTORY_QOS are handled.
The inter-entity communication was changed to allow the HC to mark
parsed changes as rejected, and allow future re-transmission (in the
case of Reliable communication).
While previously we sent the EntityID before the GUID Prefix (for some
reason), we changed swaped the order to allow easier decoding (by having
uniform format for all inputs)
