8f07312124 Move the code into functions. No behavior change.
Move almost all the code of this script into functions. There is no
intended behavior change. The goal of this commit is to make
subsequent improvements easier to follow.

A very large number of lines have been reintended. To see what's going
on, ignore whitespace differences (e.g. diff -w).

I followed the following rules:

* Minimize the amount of code that gets moved.
* Don't change anything to what gets executed or displayed.
* Almost all the code must end up in a function.
* One function does one thing. For most of the code, that's from one
  "cleanup" to the next.
* The test sequence functions (run_XXX) are independent.

The change mostly amounts to putting chunks of code into a function
and calling the functions in order. A few test runs are conditional;
in those cases the conditional is around the function call.

da1655a48e Remove temporary stack-buffer from mbedtls_mpi_fill_random()
Context: The function `mbedtls_mpi_fill_random()` uses a temporary stack
buffer to hold the random data before reading it into the target MPI.

Problem: This is inefficient both computationally and memory-wise.
Memory-wise, it may lead to a stack overflow on constrained devices with
limited stack.

Fix: This commit introduces the following changes to get rid of the
temporary stack buffer entirely:

1. It modifies the call to the PRNG to output the random data directly
   into the target MPI's data buffer.

This alone, however, constitutes a change of observable behaviour:
The previous implementation guaranteed to interpret the bytes emitted by
the PRNG in a big-endian fashion, while rerouting the PRNG output into the
target MPI's limb array leads to an interpretation that depends on the
endianness of the host machine.
As a remedy, the following change is applied, too:

2. Reorder the bytes emitted from the PRNG within the target MPI's
   data buffer to ensure big-endian semantics.

Luckily, the byte reordering was already implemented as part of
`mbedtls_mpi_read_binary()`, so:

3. Extract bigendian-to-host byte reordering from
   `mbedtls_mpi_read_binary()` to a separate internal function
   `mpi_bigendian_to_host()` to be used by `mbedtls_mpi_read_binary()`
   and `mbedtls_mpi_fill_random()`.

ef308c993f Add NIST AES GCM test vectors to single-step cipher API test suite
The test suites `test_suite_gcm.aes{128,192,256}_en.data` contains
numerous NIST test vectors for AES-*-GCM against which the GCM
API mbedtls_gcm_xxx() is tested.

However, one level higher at the cipher API, no tests exist which
exercise mbedtls_cipher_auth_{encrypt/decrypt}() for GCM ciphers,
although test_suite_cipher.function contains the test auth_crypt_tv
which does precisely that and is already used e.g. in
test_suite_cipher.ccm.

This commit replicates the test vectors from
test_suite_gcm.aes{128,192,256}_en.data in test_suite_cipher.gcm.data
and adds a run of auth_crypt_tv for each of them.

The conversion was mainly done through the sed command line

```
s/gcm_decrypt_and_verify:\([^:]*\):\([^:]*\):\([^:]*\):\([^:]*\):
\([^:]*\):\([^:]*\):\([^:]*\):\([^:]*\):\([^:]*\):\([^:]*\)/auth_crypt_tv:
\1:\2:\4:\5:\3:\7:\8:\9/
```

d3d8a64dfa Enable more compiler warnings in tests/Makefile
tests/Makefile had some unused warnings disabled unnecessarily, which
test-ref-configs.pl was turning back on. We don't need to disable these warnings
so I'm turning them back on.

ecff219e6f Change file scoping of test helpers.function
Dependent on configured options, not all of the helper functions were being
used, which was leading to warning of unused functions with Clang.

To avoid any complex compile time options, or adding more logic to
generate_test_code.py to screen out unused functions, those functions which were
provoking the warning were changed to remove static, remove them from file
scope, and expose them to the linker.
