61336848a9 Fix bug when legacy CID is enabled but not used
When legacy CID is enabled at compile time, but not used at runtime, we
would incorrectly skip the sequence number at the beginning of the AAD.

There was already two "else" branches for writing the sequence number
but none of them was taken in that particular case.

Simplify the structure of the code: with TLS 1.2 (we're already in that
branch), we always write the sequence number, unless we're using
standard CID.

945b23c46f Include platform.h unconditionally: automatic part
We used to include platform.h only when MBEDTLS_PLATFORM_C was enabled, and
to define ad hoc replacements for mbedtls_xxx functions on a case-by-case
basis when MBEDTLS_PLATFORM_C was disabled. The only reason for this
complication was to allow building individual source modules without copying
platform.h. This is not something we support or recommend anymore, so get
rid of the complication: include platform.h unconditionally.

There should be no change in behavior since just including the header should
not change the behavior of a program.

This commit replaces most occurrences of conditional inclusion of
platform.h, using the following code:

```
perl -i -0777 -pe 's!#if.*\n#include "mbedtls/platform.h"\n(#else.*\n(#define (mbedtls|MBEDTLS)_.*\n|#include <(stdarg|stddef|stdio|stdlib|string|time)\.h>\n)*)?#endif.*!#include "mbedtls/platform.h"!mg' $(git grep -l '#include "mbedtls/platform.h"')
```

Note: existing application use which accesses the struct member
(using MBEDTLS_PRIVATE) is not compatible on little-endian platforms,
but is compatible on big-endian platforms.  For systems supporting
only TLSv1.2, the underlying values are the same (=> 3).

taking argument as enum mbedtls_ssl_protocol_version:
