Gilles Peskine 06b0fcdc9b Clarification: forward and backward compatibility
The import-and-save and load-and-check parts of the tests don't have to be
actually the same test cases.

Introduce the terms “forward compatibility” and “backward compatibility” and
relate them to import-and-save and load-and-check actions.

These are clarifications of intent that do not represent an intended change
in the strategy or intended coverage.

Gilles Peskine 739e08a68d Keystore format stability test strategy
Initial revision.

Save-compare-load approach: the test case data contains attributes of
the object under test and the expected file content. Create the
object, save it, check that the file has the expected content, load
the file and check that the new object has the expected attributes.

Gilles Peskine db6b03b4f2 Remove old-style accelerator and entropy driver interfaces
The driver interfaces described in crypto_accel_driver.h and
crypto_entropy_driver.h are no longer being worked on. We do not
intend to finish the design of these interfaces or to implement them
in Mbed TLS. They have been superseded by the unified driver
interface (docs/proposed/psa-driver-interface.md), which is being
actively worked on both to finalize the specification and to implement
it in Mbed TLS.

The partially implemented dynamic secure element interface is staying
for now.

Ronald Cron cf56a0a320 psa: Move from key handle to key identifier
Move all the PSA crypto APIs using key handles
to use key identifiers but psa_key_open() and
psa_key_close(). This is done without modifying
any test as key handles and key identifiers are
now the same.

Update the library modules using PSA crypto APIs
to get rid of key handles.

Programs and unit tests are updated to not use
key handles in subsequent commits, not in this
one.

Gilles Peskine fa51820e39 Expand the rule for internal functions exposed for tests only
Clarify that using a header in library/ rather than include/ for
internal functions is a rule, not just a possibility.

As suggested by Manuel, state a rule for functions that need to be
static for best optimization but that we want to unit-test.

Gilles Peskine 9afbfdc833 Merge remote-tracking branch 'myfork-public/development' into merge-crypto-development-20191115
First deal with deleted files.

* Files deleted by us: keep them deleted.
* Files deleted by them, whether modified by us or not: keep our version.

```
git rm $(git status -s | sed -n 's/^DU //p')
git reset -- $(git status -s | sed -n 's/^D  //p')
git checkout -- $(git status -s | sed -n 's/^ D //p')
git add -- $(git status -s | sed -n 's/^UD //p')
```

Individual files with conflicts:

* `3rdparty/everest/library/Hacl_Curve25519_joined.c`: spurious conflict because git mistakenly identified this file as a rename. Keep our version.
* `README.md`: conflict due to their change in a paragraph that doesn't exist in our version. Keep our version of this paragraph.
* `docs/architecture/Makefile`: near-identical additions. Adapt the definition of `all_markdown` and include the clean target.
* `doxygen/input/docs_mainpage.h`: conflict in the version number. Keep our version number.
* `include/mbedtls/config.h`: two delete/modify conflicts. Keep the removed chunks out.
* `library/CMakeLists.txt`: discard all their changes as they are not relevant.
* `library/Makefile`:
    * Discard the added chunk about the crypto submodule starting with `INCLUDING_FROM_MBEDTLS:=1`.
    * delete/modify: keep the removed chunk out.
    * library build: This is almost delete/modify. Their changes are mostly not applicable. Do keep the `libmbedcrypto.$(DLEXT): | libmbedcrypto.a` order dependency.
    * `.c.o`: `-o` was added on both sides but in a different place. Change to their place.
* `library/error.c`: to be regenerated.
* `library/version_features.c`: to be regenerated.
* `programs/Makefile`: Most of the changes are not relevant. The one relevant change is in the `clean` target for Windows; adapt it by removing `/S` from our version.
* `programs/test/query_config.c`: to be regenerated.
* `scripts/config.py`: added in parallel on both sides. Keep our version.
* `scripts/footprint.sh`: parallel changes. Keep our version.
* `scripts/generate_visualc_files.pl`: one delete/modify conflict. Keep the removed chunks out.
* `tests/Makefile`: discard all of their changes.
* `tests/scripts/all.sh`:
    * `pre_initialize_variables` add `append_outcome`: add it.
    * `pre_initialize_variables` add `ASAN_CFLAGS`: already there, keep our version.
    * `pre_parse_command_line` add `--no-append-outcome`: add it.
    * `pre_parse_command_line` add `--outcome-file`: add it.
    * `pre_print_configuration`: add `MBEDTLS_TEST_OUTCOME_FILE`.
    * Several changes in SSL-specific components: keep our version without them.
    * Several changes where `config.pl` was changed to `config.py` and there was an adjacent difference: keep our version.
    * Changes regarding the inclusion of `MBEDTLS_MEMORY_xxx`: ignore them here, they will be normalized in a subsequent commit.
    * `component_test_full_cmake_gcc_asan`: add it without the TLS tests.
    * `component_test_no_use_psa_crypto_full_cmake_asan`: keep the fixed `msg`, discard other changes.
    * `component_test_memory_buffer_allocator_backtrace`, `component_test_memory_buffer_allocator`: add them without the TLS tests.
    * `component_test_m32_everest`: added in parallel on both sides. Keep our version.
* `tests/scripts/check-names.sh`, `tests/scripts/list-enum-consts.pl`, `tests/scripts/list-identifiers.sh`, ``tests/scripts/list-macros.sh`: discard all of their changes.
* `tests/scripts/test-ref-configs.pl`: the change in the conflict is not relevant, so keep our version there.
* `visualc/VS2010/*.vcxproj`: to be regenerated.

Regenerate files:

```
scripts/generate_visualc_files.pl
git add visualc/VS2010/*.vcxproj
scripts/generate_errors.pl
git add library/error.c
scripts/generate_features.pl
git add library/version_features.c
scripts/generate_query_config.pl
git add programs/test/query_config.c
```

Rejected changes in non-conflicting files:

* `CMakeLists.txt`: discard their addition which has already been side-ported.
* `doxygen/mbedtls.doxyfile`: keep the version number change. Discard the changes related to `../crypto` paths.

Keep the following changes after examination:

* `.travis.yml`: all of their changes are relevant.
* `include/mbedtls/error.h`: do keep their changes. Even though Crypto doesn't use TLS errors, it must not encroach on TLS's allocated numbers.
* `tests/scripts/check-test-cases.py`: keep the code dealing with `ssl-opt.sh`. It works correctly when the file is not present.
