We also convert to passing COMP_METHOD rather than SSL_COMP to the record
layer. The former is a public type while the latter is internal only - and
the only thing we need from SSL_COMP is the method.

Previously we were referencing the block_padding value through the
SSL_CONNECTION. Now it is held within OSSL_RECORD_LAYER.

We use the record layer reference to the BIO rather than the SSL object
reference. This removes an unneeded SSL object usage.

Make sure we set the write record layer method and create the object
where appropriate. Move the newly restructured writing code into the
record layer object.
For now we are cheating and still accessing the underlying SSL_CONNECTION
object. This will be removed in subsequent commits.

The new write record layer architecture splits record writing into
a "write_records" call and a "retry_write_records" call - where multiple
records can be sent to "write_records" in one go. We restructure the code
into that format in order that future commits can move these functions into
the new record layer more easily.

This allows querying of the record layer to get a human readable state
string out. This resolves two outstanding TODO comments and enables us
to remove the rstate variable from s->rlayer.

Sometimes data read by a record layer in one epoch is actually intended for
the next epoch. For example in a TLS with read_ahead, the read_ahead data
could contain a KeyUpdate message followed by application data encrypted
with new keys. Therefore we implement a mechanism for passing this data
across the epochs.
