  Log Message:
  -----------
  Add support for rstream get/release record in the QUIC TLS layer

The QUIC TLS layer was taking an internal copy of rstream data while
reading. The QUIC rstream code has recently been extended to enable a
get/release model which avoids the need for this internal copy, so we use
that instead.

  Log Message:
  -----------
  Make the data field for get_record() const

Improves consistency with the QUIC rstream implementation - and improves
the abstraction between the TLS implementation and the abstract record
layer. We should not expect that the TLS implementation should be able to
change the underlying buffer. Future record layers may not expect that.

  Log Message:
  -----------
  Allow partially releasing a record for TLS

This enables the cleansing of plaintext to occur in the record layer and
avoids the need to cast away const above the record layer.
