ef01852d65 Add missing guard to mbedtls_test_hook_error_add
Add a missing guard for the definition and declaration of
mbedtls_test_hook_error_add.

Also make the declaration always visible when MBEDTLS_TEST_HOOKS is
enabled. This fixes an issue when MBEDTLS_ERROR_C is not defined but
MBEDTLS_TEST_HOOKS is.

b7d02e0f15 Fix misc issues with unused parameters and check-names.sh
Fix unused parameter warnings when MBEDTLS_TEST_HOOKS is not enabled.

A few issues were caught by check-names.sh namely:

- mbedtls_error_add was not capitalised.
- mbedtls_test_hook_error_add was being defined multiple times as the
  definition was in a header.

7439209bcc Rewrite error addition interface
The previous implementation of the error addition interface did not comply
with the invasive testing architecture guidelines. This commit fixes that
by:

- Renaming functions/macros/variables to follow the mbedtls_error_xxx or
  mbedtls_test_hook_xxx convention.

- Making mbedtls_test_hook_error_add a global variable that can be set
  by the testing code.

- Using a static inline function call, as opposed to macro, to keep
  discrepancies between debug and production version to a minimum.

b179b84335 Change set_err_add_hook void pointer to actual function pointer signature
Change the signature of the `hook` parameter of `mbedtls_set_err_add_hook`
to use the actual signature of the function as opposed to `void *`. This
fixes a warning when compiling with clang `-pedantic`.

ef180af350 Move MBEDTLS_ERR_ADD macro and functions to error.*
`error.c` and  error.h are the more logical place to keep this code and it
prevents issues with building `common.c` and conflicts with other projects
that use mbedtls (such as mbedOS).

`error.c` has been automatically generated by first adding the code to
`error.fmt` and then running `./scripts/generate_errors.pl`.

Also add parenthesis to the addition in `MBEDTLS_ERR_ADD`.

5e8805afeb Move MBEDTLS_ERR_ADD macro and function to common.*
`error.c` is a file generated from `error.h` and thus cannot contain the code
that was previously added. This commit fixes that issue by moving the
`MBEDTLS_ERR_ADD` macro and associated function and function pointer into
`common.h` and `common.c`.

Also fix a typo in `tests/include/test/helpers.h` where tabs were accidentally
used instead of spaces.

96ae73b0ea Add macro for error code addition
Adds a macro (`MBEDTLS_ERR_ADD`) to add error codes together and check that the
result will not be corrupted. This additional check is only enabled during
testing when `MBEDTLS_TEST_HOOKS` is defined.

Also includes a reference usage example in `rsa.c` where two high-level error
codes could be incorrectly added together under the right conditions. This now
ensures that when this error occurs during testing it will be correctly
reported.

a9f64006ea Add support for const error description strings
Problem
-------
mbedtls_strerror is a utility function which converts an mbedTLS error code
into a human readable string. It requires the caller to allocate a buffer every
time an error code needs to be converted to a string. It is an overkill and a
waste of RAM for resource constrained microcontrollers - where the most common
use case is to use these strings for logging.

Solution
--------
The proposed commit adds two functions:

* const char * mbedtls_high_level_strerr( int error_code );
* const char * mbedtls_low_level_strerr( int error_code );

The above two functions convert the high level and low level parts of an mbedTLS
error code to human readable strings. They return a const pointer to an
unmodifiable string which is not supposed to be modified by the caller and only
to be used for logging purposes. The caller no longer needs to allocate a
buffer.

Backward Compatibility
----------------------
The proposed change is completely backward compatible as it does not change
the existing mbedtls_strerror function and ensures that it continues to behave
the same way.

2d20567122 Add two error codes to the Error module
One of the error codes was already reserved, this commit just makes it
explicit. The other one is a new error code for initializing return
values in the library: `MBEDTLS_ERR_ERROR_CORRUPTION_DETECTED` should
not be returned by the library. If it is returned, then it is surely a
bug in the library or somebody is tampering with the device.

f9b3303eb9 Introduce specific error for ver/cfg mismatch on deserialization
This commit introduces a new SSL error code

  `MBEDTLS_ERR_SSL_VERSION_MISMATCH`

which can be used to indicate operation failure due to a
mismatch of version or configuration.

It is put to use in the implementation of `mbedtls_ssl_session_load()`
to signal the attempt to de-serialize a session which has been serialized
in a build of Mbed TLS using a different version or configuration.

c37c96a3c5 Add specific SSL error code for unexpected CIDs
Currently, the stack silently ignores DTLS frames with an unexpected CID.
However, in a system which performs CID-based demultiplexing before passing
datagrams to the Mbed TLS stack, unexpected CIDs are a sign of something not
working properly, and users might want to know about it.

This commit introduces an SSL error code MBEDTLS_ERR_SSL_UNEXPECTED_CID
which the stack can return in response to an unexpected CID. It will
conditionally be put to use in subsequent commits.

modules. The errors are correctly sourced from Mbed TLS and not Mbed
