Gilles Peskine e655479528 Generalize representation handling in mbedtls_mpi_mod_read
Call mbedtls_mpi_mod_raw_canonical_to_modulus_rep instead of assuming that
anything that isn't MBEDTLS_MPI_MOD_REP_MONTGOMERY is canonical.

mbedtls_mpi_mod_write should get the same treatment, but I'm holding off
until https://github.com/Mbed-TLS/mbedtls/issues/6679 is done.

Gilles Peskine c377f31ad9 Remove unused import
This wasn't reported by pylint due to a pylint bug (apparently):
`pylint A B` doesn't complain about an unused import in B if A happens to
import and use the same module, which happens to be the case when we run
pylint on the CI.

Minos Galanakis e080cc31f2 pylint: Set a minimum duplicate match to 10 lines.
This patch adjusts pylint to disregard duplicate matches
for up to 10 lines.

The number is chosen to permit overriding with up to
3 identical lines for `def arguments(self)` and
`def result(self)` while two more lines for `arity`
and `input_style` in the bignum test suite.

Manuel Pégourié-Gonnard c572246fa5 Use OPENSSL everywhere, not OPENSSL_CMD
These variables were both uses to select the default version of OpenSSL
to use for tests:
- when running compat.sh or ssl-opt.sh directly, OPENSSL_CMD was used;
- when running all.sh, OPENSSL was used.

This caused surprising situations if you had one but not the other set
in your environment. For example I used to have OPENSSL_CMD set but not
OPENSSL, so ssl-opt.sh was failing in some all.sh components but passing
when I ran it manually in the same configuration and build, a rather
unpleasant experience.

The natural name would be OPENSSL, and that's what set in the Docker
images used by the CI. However back in the 1.3.x days, that name was
already used in library/Makefile, so it was preferable to pick a
different one, hence OPENSSL_CMD. However the build system has not been
using this name since at least Mbed TLS 2.0.0, so it's now free for use
again (as demonstrated by the fact that it's been set in the CI without
causing any trouble).

So, unify things and use OPENSSL everywhere. Just leave an error message
for the benefit of developers which might have OPENSSL_CMD, not OPENSSL,
set in their environment from the old days.

Gilles Peskine 9a3771e1b3 Don't touch the style of generated files
Ideally the result of the generator would conform to the code style, but
this would be difficult, especially with respect to the placement of line
breaks in long logical lines. So, to avoid surprises when checking the style
of generated files (which happens in releases and in long-time support
branches), systematically skip generated files.

Gilles Peskine 98d3a67a5c Simplify the coverage statistics summary
The script was parsing the output from `make lcov` to extract numbers and
calculate percentages. But everything including the percentages is already
present in the output of `make lcov`, just with a slightly different
presentation. So replace all this by a simple extraction of the relevant
lines from the output of `make lcov`.

This is more robust than the previous code, which relied on `tail -n4` to
extract relevant lines, which broke when `make lcov` started to emit one
extra line at the end.
