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.

When building with MBEDTLS_MEMORY_DEBUG enabled, and running the ecdh part,
the benchmark program would start writing a very large number of space
characters on stdout, and would have to be killed because it never seemed to
terminate.
This was due to an integer overflow in computing how many space to leave after
the title in order to get memory measurements aligned, which resulted in up
to SIZE_MAX spaces being printed.
This commit just fixes the overflow, the next commit is going to fix the magic
number (12).

The MBEDTLS_SSL_VARIABLE_BUFFER_LENGTH build option has been added since
the last release, but there was no entry for it in the ChangeLog.

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.

The identifiers of the unmet dependencies of a test case are
stored in a buffer of fixed size that can be potentially to
small to store all the unmet dependencies. Indicate in test
reports if some unmet dependencies are missing.

Fix potential buffer overflow when tracking the unmet dependencies
of a test case. The identifiers of unmet dependencies are stored
in an array of fixed size. Ensure that we don't overrun the array.

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...

Don't mix Windows and Unix line endings, it's the worst of both worlds.
Update the Visual Studio templates and regenerate the generated files.

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.
