7a894f2142 Move backward compatibility aliases to their own header
Move backward compatibility aliases to a separate header. Reserve
crypto_extra.h for implementation-specific extensions that we intend
to keep supporting.

This is better documentation for users. New users should simply ignore
backward compatibility aliases, and old users can look at
crypto_compat.h to see what is deprecated without bothering about new
features appearing in crypto_extra.h.

This facilitates maintenance because scripts such as
generate_psa_constants that want to ignore backward compability
aliases can simply exclude crypto_compat.h from their parsing.

8fa1348276 Enumerate metadata test functions explicitly
When gathering test cases from test_suite_psa_crypto_metadata, look up
the test function explicitly. This way test_psa_constant_names will
error out if we add a new test function that needs coverage here.

This change highlights an omission in the previous version:
asymmetric_signature_wildcard was silently ignored as a source of
algorithm expressions to test. Fix that.

7961668738 Support key agreement
Key agreement algorithms were excluded back when they were constructed
with a macro conveying the key agreement itself taking the KDF as an
argument, because that was hard to support. Now the encoding has
changed and key agreement algorithms are constructed with
PSA_ALG_KEY_AGREEMENT taking two arguments, one that identifies the
raw key agreement and one that identifies the KDF. This is easy to
process, so add support.

2bcfc714d2 Error out if a test case uses an unknown macro name
Insist that test cases must only use macro names that are declared in
a header. This may catch errors such as not parsing the intended
files.

Make this check easily overridden in a derived class.

24600e8290 Disable memory_buffer_alloc in the full config
Enabling MBEDTLS_MEMORY_BUFFER_ALLOC_C module together with
MBEDTLS_PLATFORM_MEMORY causes the library to use its own malloc
replacement. This makes memory management analyzers such as ASan
largely ineffective. We now test MBEDTLS_MEMORY_BUFFER_ALLOC_C
separately. Disable it in the "full" config.

This mirrors a change that was made in Mbed TLS on config.pl and had
not been ported to Mbed Crypto yet.

With this commit, config.py is aligned in Mbed Crypto and Mbed TLS.

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.

adc82f3535 Add set+get tests
The tests were not covering get for a symbol with a value. No symbol
has an uncommented value in the default config.h. (Actually there's
_CRT_SECURE_NO_DEPRECATE, but that's a bit of a hack that this script
is not expected to handle, so don't use it).

Add tests of "get FOO" after "set FOO" and "set FOO value", so that we
have coverage for "get FOO" when "FOO" has a value.

bc86f997ca Consolidate tests for set with/without values
We currently test setting a symbol with a value even if it didn't
originally had one and vice versa. So there's no need to have separate
lists of symbols to test with. Just test everything we want to test
with each symbol.

261742bd59 Fix config.py output when a symbol has acquired or lost a value
Normally a valueless symbol remains valueless and a symbol with a
value keeps having one. But just in case a symbol does get changed
from valueless to having a value, make sure there's a space between
the symbol and the value. And if a symbol gets changed from having a
value to valueless, strip trailing whitespace.

Add corresponding tests.

Also fix the case of a valueless symbol added with the set method,
which would have resulted in attempting to use None as a string. This
only happened with the Python API, not with the command line API.

aebf0027c0 Test script for config.py
Run config.py with various options and store the results in files.

This script also supports the now-removed config.pl.

This is a framework to run non-regression tests on config.py: run it
with the old version, run it with the new version, and compare the
output.

This is deliberately not a functional test suite so that we don't need
to maintain a set of known outputs. When something changes in
config.py (or config.h), run the script before, run it after, and
check manually whether any differences in the output are acceptable.

2e86a206f7 Remove component designed to test MAX_SIGNATURE_SIZE
MBEDTLS_PK_SIGNATURE_MAX_SIZE is tested in Mbed Crypto. Its effect on
Mbed TLS is also tested via the X.509 tests. The case of
MBEDTLS_MPI_MAX_SIZE < MBEDTLS_ECDSA_MAX_LEN, for which this component
was added as a regression test, is covered by config-suite-b.h which
is tested via test-ref-configs.pl.

ce35cb3cc7 'make test' must fail if Asan fails
When running 'make test' with GNU make, if a test suite program
displays "PASSED", this was automatically counted as a pass. This
would in particular count as passing:
* A test suite with the substring "PASSED" in a test description.
* A test suite where all the test cases succeeded, but the final
  cleanup failed, in particular if a sanitizer reported a memory leak.

Use the test executable's return status instead to determine whether
the test suite passed. It's always 0 on PASSED unless the executable's
cleanup code fails, and it's never 0 on any failure.
