Chris Jones fdb588b3a7 Fix an incorrect error code addition in pk_parse_key_pkcs8_unencrypted_der
An incorrect error code addition was spotted by the new invasive testing
infrastructure whereby pk_get_pk_alg will always return a high level
error or zero and pk_parse_key_pkcs8_unencrypted_der will try to add
another high level error, resulting in a garbage error code.

Apply the same fix from ae3741e8a to fix the bug.

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.

Chris Jones 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.

Chris Jones 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`.

Chris Jones 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.

Chris Jones 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.
