Manuel Pégourié-Gonnard c09bb4c3ab all.sh: clean up some uses of "local" variables
While pure sh doesn't have a concept of local variables, we can partially
emulate them by unsetting variables before we exit the function, and use the
convention of giving them lowercase names to distinguish from global
variables.

Manuel Pégourié-Gonnard 4f265fbff7 Use all.sh in pre-push hook
The list in the pre-push hook was redundant with the list of `check_*`
components in all.sh, and unsurprisingly it was outdated.

Missing components were:

- check_recursion
- check_changelog
- check_test_cases
- check_python_files
- check_generate_test_code

Manuel Pégourié-Gonnard 73341a0f84 Add a --quiet option to all.sh
The primary purpose is to use it to run all.sh -k -q in the pre-push hook, but
this can be useful in any circumstance where you're not interested in the full
output from each component and just want a short summary of which components
were run (and if any failed).

Note that only stdout from components is suppressed, stderr is preserved so
that errors are reported. This means components should avoid printing to
stderr in normal usage (ie in the absence of errors).

Currently all the `check_*` components obey this convention except:
- check_generate_test_code: unittest prints progress to stderr
- check_test_cases: lots of non-fatal warnings printed to stderr

These components will be fixed in follow-up commits.

Manuel Pégourié-Gonnard 138109133d Remove SHA-1 as a fallback option
- it's 2020, there shouldn't be too many systems out there where SHA-1 is the
  only available hash option, so its usefulness is limited
- OTOH testing configurations without SHA-2 reveal bugs that are not easy to
  fix in a fully compatible way

So overall, the benefit/cost ratio is not good enough to justify keeping SHA-1
as a fallback option here.

Manuel Pégourié-Gonnard 6d61498e05 Add fall-back to hash-based KDF for internal ECP DRBG
The dependency on a DRBG module was perhaps a bit strict for LTS branches, so
let's have an option that works with no DRBG when at least one SHA module is
present.

This changes the internal API of ecp_drbg_seed() by adding the size of the
MPI as a parameter. Re-computing the size from the number of limbs doesn't
work too well here as we're writing out to a fixed-size buffer and for some
curves (P-521) that would round up too much. Using mbedtls_mpi_get_len() is
not entirely satisfactory either as it would mean using a variable-length
encoding, with could open side channels.

Manuel Pégourié-Gonnard c98fde5ca8 Add test for building without CTR_DRBG
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.

Gilles Peskine 9cc203a7ea Create a seedfile explicitly
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.

Gilles Peskine 4bda3254cf Check only files checked into Git
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.
