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.

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.

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.

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.

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.

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

Fix builds where `MBEDTLS_ERROR_C` is not defined but `MBEDTLS_TEST_HOOKS`

these builds.

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`.

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.

`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`.

Fix building by adding `common.c` to the build scripts (both make and Cmake).
Also reworks the hook function pointer (also renamed to `err_add_hook`) to be
a static local to `common.c` with a setter function to set the pointer to a
checking function.

`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.

`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.
