Test mbedtls_ssl_decrypt_buf() with a stream cipher (RC4 or null). Test the
good case (to make sure the test code constructs the input correctly), test
with an invalid MAC, and test with a shortened input.

test_suite_ssl is huge and needs splitting.
Create a new test suite focused on mbedtls_ssl_decrypt_buf(), which is a
complicated function that needs more thorough testing with malformed inputs.
At this point, we are only doing negative testing with CBC-non-ETM test
suites. This needs to grow.

The official spelling of the trade mark changed from all-lowercase "mbed"
to normal proper noun capitalization "Mbed" a few years ago. We've been
using the new spelling in new text but still have the old spelling in a
lot of text. This commit updates most occurrences of "mbed TLS":
```
sed -i -e 's/mbed TLS/Mbed TLS/g' $(git ls-files ':!ChangeLog' ':!tests/data_files/**' ':!tests/suites/*.data' ':!programs/x509/*' ':!configs/tfm*')
```
Justification for the omissions:
* `ChangeLog`: historical text.
* `test/data_files/**`, `tests/suites/*.data`, `programs/x509/*`: many
occurrences are significant names in certificates and such. Changing
the spelling would invalidate many signatures and tests.
* `configs/tfm*`: this is an imported file. We'll follow the upstream
updates.

* Prevent pkcs12_pbe encryption when PKCS7 padding has been
disabled since this not part of the specs.
* Allow decryption when PKCS7 padding is disabled for legacy
reasons, However, invalid padding is not checked.
* Document new behaviour, known limitations and possible
security concerns.
* Add tests to check these scenarios. Test data has been
generated by the below code using OpenSSL as a reference:

When calling `add_xxx_ciphersuites`, we have to set MODE properly.

uniform_title is used to print identical format of $TITLE between

Test case description is printed by different block of code. This
causes code maintenance harder since we need to maintain two parts
of code with same functionality. print_test_title is used to
control test case description in compat.sh

Test case description in compat.sh is in format of

This program calls compat.sh to list all potential test case
descriptions then checks test case duplication.

The option --list-test-case lists all potential test cases without
executing them. The test case description is identical with $TITLE

* Turn the warnings produced when finding non-executed tests that
are not in the allow list into errors.
Signed-off-by: Tomás González <tomasagustin.gonzalezorlando@arm.com>
Introduce the --require-full-coverage in analyze_outcomes.py so that
when analyze_outcomes.py --require-full-coverage is called, those
tests that are not executed and are not in the allowed list issue an
error instead of a warning.
Note that it is useful to run analyze_outcomes.py on incomplete test
results, so this error mode needs to remain optional in the long
term.
