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.

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`.

`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.

All occurences of manual error code addition/combination, in `rsa.c`, have
been replaced with the `MBEDTLS_ERR_ADD` macro.
Signed-off-by: Chris Jones <christopher.jones@arm.com>
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.

As we want to do Mbed TLS aead operations as a
driver does, aead operations should not access
the key slot as key slots are not available to
drivers.
Second step in this PR: do not unlock the key slot
as part of operation abort.

Fix the subtraction in fix_negative, which was incorrectly not looking
for a carry. This caused the result to be wrong when the least
significant limb of N was 0. Fix#4296.
The bug was introduced by d10e8fae9e30cac60297b1e1834002db183429e5
"Optimize fix_negative". Thanks to Philippe Antoine (catenacyber) for
reporting the bug which was found by his EC differential fuzzer.

Move the handling of the sign out of the base-specific loops. This
both simplifies the code, and corrects an edge case: the code in the
non-hexadecimal case depended on mbedtls_mpi_mul_int() preserving the
sign bit when multiplying a "negative zero" MPI by an integer, which
used to be the case but stopped with PR #2512.
Fix#4295. Thanks to Guido Vranken for analyzing the cause of the bug.
