People who prefer to rely on HMAC_DRBG (for example because they use it for
deterministic ECDSA and don't want a second DRBG for code size reasons) should
be able to build and run the tests suites without CTR_DRBG.
Ideally we should make sure the level of testing (SSL) is the same regardless
of which DRBG modules is enabled, but that's a more significant piece of work.
For now, just ensure everything builds and `make test` passes.

Running the entropy unit test creates a suitable seedfile, but this
only works due to the happy accident that no prior unit test needs one
(specifically, test_suite_entropy runs before test_suite_rsa). So
create one explicitly, both for robustness and to keep the script
closer to the version in development where the explicit seedfile
creation is required.

We're only interested in files that are committed and pushed to be
included in Mbed TLS, not in any other files that may be lying around.
So ask git for the list of file names.
This script is primarily intended to run on the CI, and there it runs
on a fresh Git checkout plus potentially some other checkouts or
leftovers from a previous part of the CI job. It should also run
reasonably well on developer machines, where there may be various
additional files. In both cases, git is available.
Ad hoc directory exclusions are no longer needed.

Have an explicit list of exemptions for specific checks rather than
whitelisting files to check. Some checks, such as permissions, should
apply to all files.

Backport this component that was added to development after 2.7.0.
It's easier to keep the 2.7 branch closer to the other maintained
branches.

This is supposed to be for GCC (or a compiler with a compatible
command line interface) targeting arm-none-eabi, so name it
accordingly.

build_deprecated combined the testing of deprecated features, and
testing of the build without deprecated features. Also, it violated the
component naming convention by being called build_xxx but running tests.
Replace it by:
* test_default_no_deprecated: check that you can remove deprecated
features from the default build.
* test_full_deprecated_warning: check that enabling DEPRECATED_WARNING
doesn't cause any warning from our own code.

The intended logic around MBEDTLS_xxx_ALT is to exclude them from full
because they require the alternative implementation of one or more
library functions, except that MBEDTLS_PLATFORM_xxx_ALT are different:
they're alternative implementations of a platform function and they
have a built-in default, so they should be included in full. Document
this.
Fix a bug whereby MBEDTLS_PLATFORM_xxx_ALT didn't catch symbols where
xxx contains an underscore. As a consequence, MBEDTLS_PLATFORM_NV_SEED_ALT
is now enabled in the full config. Explicitly exclude
MBEDTLS_PLATFORM_SETUP_TEARDOWN_ALT because it behaves like the
non-platform ones, requiring an extra build-time dependency.
Explicitly exclude MBEDTLS_PLATFORM_NV_SEED_ALT from baremetal
because it requires MBEDTLS_ENTROPY_NV_SEED, and likewise explicitly
unset it from builds that unset MBEDTLS_ENTROPY_NV_SEED.

Make it possible to use a compiler that isn't in $PATH, or that's
installed with a different name, or even a compiler for a different
target such as arm-linux-gnueabi.

Almost everything the selftest program does is in the test suites. But
just in case run the selftest program itself once in the full
configuration, and once in the default configuration with ASan, in
addition to running it out of box.

To test a file name exactly, prepend a / to the base name.
files_to_check actually checks suffixes, not file names, so rename it

Goals:
* Build with common compilers with common options, so that we don't
miss a (potentially useful) warning only triggered with certain
build options.
* A previous commit removed -O0 test jobs, leaving only the one with
-m32. We have inline assembly that is disabled with -O0, falling
back to generic C code. This commit restores a test that runs the
generic C code on a 64-bit platform.
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.

Some sanitizers default to displaying an error message and recovering.
This could result in a test being recorded as passing despite a
complaint from the sanitizer. Turn off sanitizer recovery to avoid
this risk.
Exercise the library functions with calloc returning NULL for a size
of 0. Make this a separate job with UBSan (and ASan) to detect
places where we try to dereference the result of calloc(0) or to do
things like
buf = calloc(size, 1);
if (buf == NULL && size != 0) return INSUFFICIENT_MEMORY;
memcpy(buf, source, size);
which has undefined behavior when buf is NULL at the memcpy call even
if size is 0.
This is needed because other test components jobs either use the system
malloc which returns non-NULL on Linux and FreeBSD, or the
memory_buffer_alloc malloc which returns NULL but does not give as
useful feedback with ASan (because the whole heap is a single C
object).
