This program can be used to validate that things that should be detected as
test failures are indeed caught, either by setting the test result to
MBEDTLS_TEST_RESULT_FAILED or by aborting the program.

mbedtls_ssl_session_save() always outputs the output length, even on error.
Here, we're only calling it to get the needed output length, so it's ok to
ignore the return value. Convey this to linters.

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.

Every now and then, I see of these programs failing with a super-long
usage message that gives no clue as to what went wrong. (Recently it
happened with a test case in ssl-opt.sh with a fairly long command line
that was entirely correct, except some options were not valid in this
config - the test should have been skipped but wasn't due to some other
bug. It took me longer to figure out than it should have, and could have
if the program had simply reported which param was not recognized.)
Also, have an explicit "help" command, separate "help_ciphersuites", and
have default usage message that's not multiple screens long.

All options have reasonable default so the programs don't need arguments
to do something useful.
It is widely accepted for programs that can work without arguments need
not insist on the user passing arguments, see 'ls', 'wc', 'sort', 'more'
and any number of POSIX utilities that all work without arguments.
It is also the historical behaviour of those programs, and something
relied one by at least a few team members.

Running clang-16 on mbedtls reports warnings of type "-Wstrict-prototypes".
This patch fixes these warnings by adding void to functions with no
arguments. The generate_test_code.py is modified to insert void into test
functions with no arguments in *.function files.

Demo scripts should declare their build-time dependencies, to make
them more user-friendly. If a dependency is not met, users should see
an explicit message rather than an incomprehensible error.
Don't rely on the dependencies of individual programs because some
demo scripts use multiple programs and because some scripts might have
additional requirements.

The new file programs/demo_common.sh contains initialization code,
utility functions and cleanup code meant to be used by all demo
scripts written in sh.
Initial features:
* msg: Display a message.
* run, run_bad: Run a command, visibly.
* $root_dir, $programs_dir: location of the mbedtls source tree.
* $files_to_clean: files that are cleaned up on exit.

crypt_and_hash decryption fails when used with a stream cipher
mode of operation due to the input not being multiple of block
size, this only applies to block cipher modes and not stream
ciphers.This change exempts CTR, CFB & OFB modes from this check.

Allow demo scripts to be run from the build directory for out-of-tree
builds.
If the executable is not found in the source tree then search in the
current directory in case the script is being run from a build
directory.

We don't commit *.o files anywhere, not even as test data. So ignore them
everywhere.
Also remove a redundant ignore of *.exe in a subdirectory.

The fuzz programs were returning a nonzero status if they failed to load the
reproducer, but that's discreet and not informative. Make them also print an
error message.
