Instead, we insert a comment containing GDB_BREAK_HERE in the line we
want to break at, and let the gdb script search for it.

Similarly to the recently-added tests for dependencies on CTR_DRBG:
constrained environments will probably want only one DRBG module, and we
should make sure that tests pass in such a configuration.

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.

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.

This is supposed to be for GCC (or a compiler with a compatible

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.

Use "no_deprecated" both in the name of the configuration and in the
name of all.sh components, rather than a mixture of "no_deprecated"
and "non_deprecated".
Make all.sh component names more consistent.

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_no_deprecated: check that the library builds when deprecated
features are disabled (and incidentally that the tests run).
* test_no_deprecated_warning: check that there are no warnings when
deprecated features are disabled and MBEDTLS_DEPRECATED_WARNING
is enabled.
* test_deprecated: test the deprecated features.

It's deprecated, but not otherwise counter-indicated for the full
config: it doesn't conflict with anything and enabling it doesn't make
testing harder (especially since it defaults off in compat.sh).

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_GMTIME_R_ALT and MBEDTLS_PLATFORM_NV_SEED_ALT are 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.

The seedfile needs to have the size of the entropy accumulator, which
is 64 bytes (512 bits) since the entropy accumulator uses SHA-512 and
the seed size needs to be the same as the hash output (or larger).
We used to enable MBEDTLS_ENTROPY_FORCE_SHA256 in the full config, so
the entropy accumulator was 256 bits (32 bytes), and therefore a
32-byte seedfile worked. But we no longer turn on this option in the
full config, so the 32-byte seedfile no longer works.
