* replace tbb::concurrent_queue by std::vector and mutex
  because the concurrent queue does not support thread-safe swap
* allows fast acquisition of _all_ messages from the connection
* in the typical use case of sending, waiting until halt and receiving
  this leads to less time spend with exclusive access to the connection
  and therefore more possible parallelism
* remove single-message receive() and try_receive() interface

  reorder members.

* A send queue consisting of a single packet of HostARQ is used
* full packets are sent automatically
* this involves the implementation change, that add() is allowed
  to transfer to the hardware and commit only guarantees all
  messages added until now are sent
* beforehand during we did never communicate to the hardware
* no heap allocation used as part of encoding and sending in
  the connection
* maximal encoding latency is the time to encode a single packet
* since encoding speed at the moment is around 800MB/s, maximal
  throughput without this change is 1/(1/800 + 1/125) = 108 MB/s,
  which is only 86% of full gigabit
* with this change if encoding is faster than the transfer,
  the full transfer bandwidth can be used

Not all connections will support the full direct-access interface that
the default implementation of Stream provides but rather only the subset
needed for execute_messages()-invocations.

* Introduce `ConnectionFullStreamInterfaceVariant` that is merely a
  filtered version of the full `ConnectionVariant` with those types
  removed that do not support the full(= default) Stream interface.

* Introduce `get_connection_full_stream_interface_from_env()` that gets
  the connection defined by the environment but checks if it can support
  the full_stream_interface. If so the connection is wrapped in an
  `optional`, otherwise nullopt is returned.

* Tests are then skipped at runtime via `GTEST_SKIP` if the optional is
  empty.

Since we cannot use aliases for unspecified templates (see point 2.2
here:
http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2002/n1406.pdf),
having templated template parameters is of less use than anticipated
because we cannot have a single source of truth in regards to what
sequence-like type is used throughout the stack.

Solution:
* Replace all `template <typename> class Sequence` parameters with
  helper structs that map the connection-type to return-/arugment-types
  for execute_messages.
  If we ever decide to switch from vector to some other sequence, only
  this mapping will have to be updated.

* Extend `GetMessageTypes`-helper struct so that it maps
  `ConnectionParameters` to `MessageTypes` directly besides extracting
  `message_types`-argument from connection-types.
  This is important so that the RCF-interface in xiggeldy can derive its
  interface from the execute_messages-signature.
