We shouldn't free the prev BIO in ssl_set_new_record_layer until it is
no longer referenced by s->rlayer.rrlnext.

Matt Caswell c20d923b46 Release zero length handshake fragment records
If we are processing a hanshake fragment and we end up with a
zero length record, then we still need to release it to avoid an
infinite loop.

Matt Caswell 7a4e109ebe 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.

Matt Caswell 2eb91b0ec3 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.
