This test helper reads an MPI from a string and guarantees control over the
number of limbs of the MPI, allowing test cases to construct values with or
without leading zeros, including 0 with 0 limbs.

Improve comments explaining error code checking, fix incorrect comments
and make a small formatting fix.

Improve documentation by:
- Fixing off by one errors in binary representations of error codes.
- Clarifying combinations of zero.
- Linking references to variables/macros via doxygen.

Although not commonly done, it should be possible to add error codes
together even if the high level error code is equal to zero.

Previously an error message was printed and then the test manually exited
via `mbedtls_exit( 1 )`. This commit includes a rebase onto:
540320bf7b so that `mbedtls_test_fail` can
be used instead to properly fail tests (and report them as such).

Add new checks and specific error messages to `mbedtls_test_err_add_check`.
This should now catch all types of error when combining error codes and
provide a specific error message to explain what occured.

`mbedtls_test_err_add_check` was previously incorrectly throwing an error if
both error codes were correct and valid pure error codes. This change fixes
that behaviour to correctly throw errors when invalid combinations are found.

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.

Add a new function `mbedtls_test_info_reset()` to remove direct writes to
`mbedtls_test_info`. This change still allows values to be read directly
however all writes are now done inside of `helpers.c`.
Also slightly reordered code to make it easier to read.

Adds the `mbedtls_` prefix to `test_result_t` and `test_info` and updates
any references to them. This is to follow the naming convention as these are
now declared in a public namespace.

Moves the functions `test_fail`, `test_set_step`, `test_skip` and the struct
`test_info` from `tests/suites/helpers.function` to `tests/src/helpers.*`.
This is done to open these functions up to the API where they can be used by
other functions in the 'src' test infrastructure module.
As the functions are now contained within the src folder of the testing
infrastructure, the `mbedtls_` prefix has been added to the functions.

As a result, the copyright of contributors other than Arm is now
acknowledged, and the years of publishing are no longer tracked in the
source files.
Also remove the now-redundant lines declaring that the files are part of
MbedTLS.

This makes the implementation of mbedtls_param_failed()
for testing purpose available to programs. Thus removing
the ad-hoc implementations in programs.

Rework mbedtls_test_unhexify to extend its scope of usage.
Return in error when the function detects an error instead
of calling mbedtls_exit().
Improve safety by checking the output buffer is not overrun.

The purpose of helpers.c file is to contain the helper
functions that have been in helpers.function so far and
that are not related to the mechanism of unit test
execution and not related to random number generation
(will be moved in a dedicated file).
The purpose of helpers.h is to contain the interface
exposed by helpers.c thus helper function prototypes.
Make the changes in the build systems (make and cmake)
to build helpers.c and link it to test executables
along with mbedtls library.
