9727f4e7fd Use a fetched cipher for the TLSv1.3 early secret
We should use an explicitly fetched cipher to ensure that we are using
the correct libctx and property query.

c8f6c28a93 Explicitly fetch ciphers and digests in libssl
We modify libssl to use explicitly fetched ciphers, digests and other
algorithms as required based on the configured library context and
property query string for the SSL_CTX that is being used.

8b6ffd4040 Params: change UTF8 construct calls to avoid explicit strlen(3) calls.
It is better, safer and smaller to let the library routine handle the
strlen(3) call.

Added a note to the documentation suggesting this.

706457b7bd Reorganize local header files
Apart from public and internal header files, there is a third type called
local header files, which are located next to source files in the source
directory. Currently, they have different suffixes like

  '*_lcl.h', '*_local.h', or '*_int.h'

This commit changes the different suffixes to '*_local.h' uniformly.

555cbb328e Collapse ssl3_state_st (s3) into ssl_st
With the removal of SSLv2, the s3 structure is always allocated, so
there is little point in having it be an allocated pointer. Collapse
the ssl3_state_st structure into ssl_st and fixup any references.

This should be faster than going through an indirection and due to
fewer allocations, but I'm not seeing any significant performance
improvement; it seems to be within the margin of error in timing.

7426cd343d Ensure that we write out alerts correctly after early_data
If we sent early_data and then received back an HRR, the enc_write_ctx
was stale resulting in errors if an alert needed to be sent.

Thanks to Quarkslab for reporting this.

In any case it makes little sense to encrypt alerts using the
client_early_traffic_secret, so we add special handling for alerts sent
after early_data. All such alerts are sent in plaintext.

Remove an out of date macro for TLS13_AD_END_OF_EARLY_DATA. This is a left

4d89bf4484 Fix TLSv1.3 exporter
We need to use the hashsize in generating the exportsecret not 0! Otherwise
we end up with random garbage for the secret.

It was pure chance that this passed the tests previously. It so happens
that, because we call SSL_export_keying_material() repeatedly for different
scenarios in the test, we end up in the tls13_export_keying_material() at
exactly the same position in the stack each time and therefore end up using
the same random garbage secret each time!
