The "full" configuration excludes some deprecated or experimental
features. Enable the ones that have tests, don't have extra
requirements and don't turn off some other feature.

The seedfile needs to have the size of the entropy accumulator, which
is 64 bytes (512 bits) since the entropy accumulator uses SHA-512 and
the seed size needs to be the same as the hash output (or larger).
We used to enable MBEDTLS_ENTROPY_FORCE_SHA256 in the full config, so
the entropy accumulator was 256 bits (32 bytes), and therefore a
32-byte seedfile worked. But we no longer turn on this option in the
full config, so the 32-byte seedfile no longer works.

This commit introduces two changes:
- Add in_msg and out_msg calculations for buffer upsizing. This was previously
considered as unnecessary, but renegotiation using certain ciphersuites needs
this.
- Improving the way out_msg and in_msg pointers are calculated, so that even
if no resizing is introduced, the pointers remain the same;
New tests added:
- various renegotiation schemes with a range of MFL's and ciphersuites;
- an ssl-opt.sh test exercising two things that were problematic: renegotiation
with TLS-ECDHE-ECDSA-WITH-AES-128-CCM-8 and a server MFL that's smaller
than the one negotiated by the client.

Since the server might want to have a different maximum fragment length
for the outgoing messages than the negotiated one - introduce a new way of
computing it. This commit also adds additional ssl-opt.sh tests ensuring
that the maximum fragment lengths are set as expected.
mbedtls_ssl_get_max_frag_len() is now a deprecated function,
being an alias to mbedtls_ssl_get_output_max_frag_len(). The behaviour
of this function is the same as before.

t is never used uninitialized, since the first loop iteration reads 0
bytes of it and then writes hash_len bytes, and subsequent iterations
read and write hash_len bytes. However this is somewhat fragile, and
it would be legitimate for a static analyzer to be unsure.
Initialize t explicitly, to make the code clearer and more robust, at
negligible cost.

Adding .function was necessary, as otherwise ctags would have no idea what to
do with those files.
Adding .h may not be necessary, as by default ctags considers them C++ which
is probably good enough, but since we're tuning the mapping anyway...

Update issue template to direct questions to the TrustedFirmware.org
mailing list instead of using the GitHub issue tracker.

Previously, doxygen was unable to effectively use preprocessing to determine
which parts of code should be documented. This was due to its inability to
include headers during preprocessing, which was discovered by running it in
preprocessing debug mode:
doxygen -d preprocessor mbedtls.doxyfile
An example of failure: "#include mbedtls/config.h: not found! skipping..."
With the following fix includes are properly preprocessed with the documentation
being considerably larger.

The current logging was sub-standard, in particular there was no trace
whatsoever of the HelloVerifyRequest being sent. Now it's being logged with
the usual levels: 4 for full content, 2 return of f_send, 1 decision about
sending it (or taking other branches in the same function) because that's the
same level as state changes in the handshake, and also same as the "possible
client reconnect" message" to which it's the logical continuation (what are we
doing about it?).

Fix an intermittent crash when running test suites in non-verbose
mode (i.e. with -v off) and with the outcome file enabled. The
array unmet_dependencies was only filled in verbose mode, but was used
in write_outcome_result regardless.
Since unmet_dependencies only ever contains strings that are integers
written out in decimal, store the integer instead. Do this
unconditionally since it doesn't cost any extra memory.
It would be better to record the dependency names, both in the verbose
output and in the outcome file. But the dependency names are not
currently available at runtime.
