e52fd3fa55 Fix integer overflow in benchmark program
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).

Let's make sure we do, by having a proxy-in-the-middle inject a ClientHello -
the server should notice, but not destroy the connection.

b99bd39b4e Merge mbed-crypto into mbedtls: the merge commit
Merge `unremove-non-crypto` into `mbedtls/development`. The branch
`unremove-non-crypto` was obtained by starting from `mbed-crypto/development`,
then reverting many commits that removed X.509 and TLS functionality when Mbed
Crypto forked from Mbed TLS (the “unremoval”), then make a few tweaks to
facilitate the merge.

The unremoval step restored old versions of some tls files. If a file doesn't
exist in mbed-crypto, check out the mbedtls version, regardless of what
happened during the unremoval of tls files in the crypto tree. Also
unconditionally take the mbedtls version of a few files where the
modifications are completely project-specific and are not relevant in
mbed-crypto:

* `.github/issue_template.md`: completely different. We may want to reconcile
  them independently as a follow-up.
* `.travis.yml`: would only be reverted to an earlier tls version.
* `README.md`: completely different. We may want to reconcile them
  independently as a follow-up.
* `doxygen/input/doc_mainpage.h`: the changes in crypto were minimal and not
  relevant except as a stopgap as mbed-crypto did not have its own product
  versioning in the Doxygen documentation.
* `tests/.jenkins/Jenkinsfile`: completely different.
* `tests/data_files/Makefile`: there were no changes in mbed-crypto,
  but the unremoval step restored an old version.

Shell script for everything to do after the merge apart from the conflict
resolution:
```
tls_files=($(comm -23 <(git ls-tree -r --name-only HEAD) <(git ls-tree -r --name-only $(git merge-base upstream-crypto/development MERGE_HEAD))))
tls_files+=($tls_files .github/issue_template.md .travis.yml README.md doxygen/input/doc_mainpage.h tests/.jenkins/Jenkinsfile tests/data_files/Makefile)
git checkout --theirs HEAD -- $tls_files
git add -- $tls_files
```

Resolve the remaining conflicts:

* `library/CMakeLists.txt`:
    * Keep the TLS definition of `src_crypto`
    * `USE_SHARED_MBEDTLS_LIBRARY`: keep all three libraries, with both
      `include` and `crypto/include` in `target_include_directories`, all with
      version `2.21.0`.
* `programs/Makefile`:
    * Reconcile the APPS lists (add/add from a differently-formatted common
      ancestor): insert the `psa/*` from crypto into the tls list.
    * Keep the `fuzz` target defined only in tls version.
    * Keep the recipe (only in tls version) cleaning `ssl_pthread_server`
      stuff for the `clean` target.
* `scripts/config.py`:
    * `include_in_full`: add/add conflict. Keep both.
* `tests/scripts/all.sh`:
    * `component_test_no_use_psa_crypto_full_cmake_asan`: partially old
      version in crypto. Take the tls version.
    * `component_test_malloc_0_null` and more: take
      `component_test_malloc_0_null` from crypto (with `config.py` rather than
      `config.pl`, and with `$ASAN_FLAGS` rather than an explicit list), but
      add the call to `ssl-opt.sh` from tls. Take the other components from
      crypto.

With this commit, building and running the unit tests with both `make ` and
`cmake` work in the default configuration on Linux. Other platforms, build
systems and configurations are likely not to work, and there is some
regression in test coverage.

There is some loss of functionality because the unremoval step restored older
versions of tls content. This commit contains the latest tls version of
tls-only files, but some changes from the tls side in files that existed on
both sides have regressed. Most problematic changes are hunks that remove some
tls-specific feature and contain either a C preprocessor symbol identifying a
tls-specific module or option, or the name of a tls-specific file. Hunks
that remove a tls-specific preprocessor symbol can be identified with the
regular expression `^-.*MBEDTLS_(ERR_)?(PKCS11|X509|NET|SSL)_`.

Subsequent commits will revert a few parts of the patch from this merge commit
in order to restore the tls functionality that it removes, ensure that the
test coverage includes what was covered in either branch, and fix test
failures.

db0cb2578c Fix CTR_DRBG benchmark
You can't reuse a CTR_DRBG context without free()ing it and
re-init()ing. This generally happened to work, but was never
guaranteed. It could have failed with alternative implementations of
the AES module because mbedtls_ctr_drbg_seed() calls
mbedtls_aes_init() on a context which is already initialized if
mbedtls_ctr_drbg_seed() hasn't been called before, plausibly causing a
memory leak. Calling free() and seed() with no intervening init fails
when MBEDTLS_THREADING_C is enabled and all-bits-zero is not a valid
mutex representation. So add the missing free() and init().

e123395317 cmake: link programs that only use crypto with libmbedcrypto
When building with CMake, for sample programs that only use
functionality in libmbedcrypto (i.e. crypto and platform), link with
libmbedcrypto, not with libmbedtls.

This doesn't change the result, because the linker skips libraries in
which no symbol is used, but it changes the build dependencies, and it
has the advantage of bringing programs/*/CMakeLists.txt closer to the
corresponding files under crypto/.

The programs concerned are crypto sample and test programs, and
programs that only use (potential) platform functions such as
mbedtls_printf. dh_client and dh_server keep linking with mbedtls
because they use functions from the net_sockets module.

7cb47de12a query_config: Move to programs/test
As the SSL programs, like ssl_client2 and ssl_server2, are dependent on

is the query_compile_time_config test. As such, it makes sense to move
query_config to be next to what uses it.
