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.

In the full config, don't set MBEDTLS_DEPRECATED_WARNING. This is debatable:
the full config does not enable deprecated features in this branch, so
MBEDTLS_DEPRECATED_WARNING is compatible with the other features.
Exclude it to keep LTS branches closer to development.
In any case, baremetal and full should have the same settings regarding
deprecated features, so don't do anything about DEPRECATED_xxx in baremetal.

Don't use string literals that are longer than 4095 bytes, which is
the minimum that C99 compilers are required to support. Compilers are
extremely likely to support longer literals, but `gcc -std=c99 -pedantic`
complains.

It works in practice on almost every platform, given that we're only
using the wrong type in cases where the value is guaranteed to stay
within the value bits of a signed int. But even in this case it may or
may not be strictly conforming. Anyway `gcc -std=c99 -pedantic`
rejects it.

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.

When parsing a certificate with the basic constraints extension
the max_pathlen that was read from it was incremented regardless
of its value. However, if the max_pathlen is equal to INT_MAX (which
is highly unlikely), an undefined behaviour would occur.
This commit adds a check to ensure that such value is not accepted
as valid. Relevant tests for INT_MAX and INT_MAX-1 are also introduced.
Certificates added in this commit were generated using the
test_suite_x509write, function test_x509_crt_check. Input data taken
from the "Certificate write check Server1 SHA1" test case, so the generated
files are like the "server1.crt", but with the "is_ca" field set to 1 and
max_pathlen as described by the file name.

When building with MBEDTLS_MEMORY_DEBUG enabled, and running the ecdh part,
the benchmark program would start writing a very large number of space
characters on stdout, and would have to be killed because it never seemed to
terminate.
This was due to an integer overflow in computing how many space to leave after
the title in order to get memory measurements aligned, which resulted in up
to SIZE_MAX spaces being printed.
This commit just fixes the overflow, the next commit is going to fix the magic
number (12).

If we take the trouble of using pass, it's because we think the code
is clearer that way. For example, Pylint 2.4 rejects pass in
def foo():
"""Do nothing."""
pass
But relying on a docstring as the sole code is weird, hence the use of
pass.

Pylint warns about things like ``log.info('...'.format(...))``.
It insists on ``log.info('...', ...)``.
This is of minor utility (mainly a performance gain when there are
many messages that use formatting and are below the log level).
Some versions of Pylint (including 1.8, which is the version on
Ubuntu 18.04) only recognize old-style format strings using '%',
and complain about something like ``log.info('{}', foo)`` with
logging-too-many-args (Pylint supports new-style formatting if
declared globally with logging_format_style under [LOGGING] but
this requires Pylint >=2.2).
Disable this warning to remain compatible with Pylint 1.8 and not have
to change abi_check.py to use %-formats instead of {}-formats when
logging.

check_python_files was optional in all.sh because we used to have CI
machines where pylint wasn't available. But this had the downside that
check_python_files kept breaking because it wasn't checked in the CI.
Now our CI has pylint and check_python_files should not be optional.

On some systems, such as Ubuntu up to 19.04, `pylint` is for Python 2
and `pylint3` is for Python 3, so we should not use `pylint` even if
it's available.
Use the Python module instead of the trivial shell wrapper. This way
we can make sure to use the correct Python version.
