Do not use the return values of
mbedtls_ssl_get_early_data_status()
(MBEDTLS_SSL_EARLY_DATA_STATUS_ macros)
for the state of the negotiation and
transfer of early data during the
handshake.

The endpoint and version were factorized out into the main session.
Update the session struct comment to reflect these new fields, as was
previously missed.

Ensure that session save and load functions are not scattered
throughout ssl_tls.c but are in the same part of the file.

Add config bits for server name indication, early data and record size
limit, which all cause the serialized session to be structured
differently.

This config option decides whether the session stores the entire
certificate or just a digest of it, but was missing from the
serialization config bitflag.

The main purpose of the change is to
know from the status, at any point in
the handshake, if early data can be
sent or not and why.

Add discard_early_data_record in SSL context for
the record layer to know if it has to discard
some potential early data record and how.

Due to the scope reduction for
mbedtls_ssl_read_early_data(), on
server as early data state variable
we now only need a flag in the
handshake context indicating if
the server has accepted early data
or not.

Due to the scope reduction of mbedtls_ssl_read_early_data()
it is not necessary anymore to refine the usage
of early_data_status/state rather the opposite.

Introduce early_data_state SSL context field to
distinguish better this internal state from
the status values defined for the
mbedtls_ssl_get_early_data_status() API.
Distinguish also between the client and
server states. Note that the client state
are going to be documented and reworked
as part of the implementation of
mbedtls_ssl_write_early_data().

Move the save/load of session endpoint and
ciphersuite that are common to TLS 1.2 and
TLS 1.3 serialized data from the
specialized ssl_{tls12,tls13}_session_{save,load}
functions to ssl__session_{save,load}.
