b9930e7d70 Add dummy tls1.3 handshake dispatch functions
Base on version config, `handshack_{clinet,server}_step`
will call different step function. TLS1.3 features will
be gradully added base on it.

And a new test cases is added to make sure it reports
`feature is not available`.

c46e9b4091 tests: Add negative version config tests.
tls1.3 and tls1.2 can not be enabled at same
time before #4832 resolved.

And the test won't run into `handshake` stage, add
`skip_handshak_check` function to skip it.

f3cce8b0e1 Add handshake message writing variant that doesn't update checksum
The helper `mbedtls_ssl_write_handshake_msg` writes a handshake message
and updates the handshake transcript.

With TLS 1.3, we need finer control over the checksum: updating
at message granularity is not sufficient. To allow for manual maintenance
of the checksum in those cases, refine `mbedtls_ssl_write_handshake_msg()`
into `mbedtls_ssl_write_handshake_msg_ext()` which takes a parameter
determining whether the checksum should be updated.

There are two packages to choose from: armhf or armel. Since the comment
in all.sh says we're trying to be close to Debian's "armel"
architecture, choose that, and fix a comment that was mentioning
gnueabihf for no apparent reason.

d297157fe8 Move MBEDTLS_ERR_xxx Doxygen comments before the definition
Now that descriptions of error codes no longer have to be on the same line
for the sake of generate_errors.pl, move them to their own line before the
definition. This aligns them with what we do for other definitions, and
means that we no longer need to have very long lines containing both the C
definition and the comment.

```
perl -i -pe 's~^(#define +MBEDTLS_ERR_\w+ +-\w+) */\*[*!]<(.*)\*/~/**$2*/\n$1~' include/mbedtls/*.h
```

47b09567ab More flexible parsing of Doxygen comments for MBEDTLS_ERR_xxx
Before this commit, definitions of error codes must match a strict pattern,
with a Doxygen comment following the definition on the same line and
starting with "/**<". Change how generate_errors.pl so that the Doxygen
comment can be before the definition instead of after, and doesn't have to
be on the same line.

Also allow spaces between "#" and "define", and allow Doxygen comments to
start with "/*!" rather than "/**". Starting with "///" or "//!" is not
supported.

This commit does not change the output of generate_errors.pl.

a77d005d39 Add known answer tests for TLS 1.3 record protection
This commit adds four known answer tests for TLS 1.3 record protection
from the following sources:

- RFC 8448 "Example Handshake Traces for TLS 1.3"
- tls13.ulfheim.net "The New Illustrated TLS Connection"

It extends the test coverage of the existing record protection tests
in the following ways:

- The existing record protection tests hand-craft record transform
  structures; the new tests use the function

     mbedtls_ssl_tls13_populate_transform()

  from library source to create an TLS 1.3 transform from raw
  key material and connection information.
- The existing record protection tests only check that encryption
  and decryption are inverse to each other; as such, they don't
  catch non-compliant implementations of encryption and decryption
  which happen to be inverse to each other. By adding a known answer
  test for TLS 1.3 record protection, can gain confidence that our
  implementation is indeed standards-compliant.

79e2d1b6f6 Fix AEAD additional data computation for TLS 1.3
The AEAD additional data (AAD) is computed differently in TLS 1.3
compared to TLS 1.2, but this change hasn't yet been reflected in
the codee, rendering the current implementation of

```
   mbedtls_ssl_{encrypt,decrypt}_buf()
```

not standard compliant.

This commit fixes this by adjusting the AAD extraction function
ssl_extract_add_data_from_record() and its call-sites.

Please see the documentation of the code for an explanation
of how the AAD has changed from TLS 1.2 to TLS 1.3.
