Merge pull request #5426 from gilles-peskine-arm/ssl-get-version-3.1 
Add accessors to mbedtls_ssl_context: user data, version
ABI-API-checking fails which was expected as this PR adds a new field in mbedtls_ssl_context and mbedtls_ssl_config.

57bf02bd58 ssl_conf_{min,max}_version documentation: update for 1.3 and improve 
Mention that TLS 1.3 is supported, in addition to (D)TLS 1.2.

Improve and clarify the documentation. In particular, emphasise that the
minor version numbers are the internal numbers which are off by one from the
human numbers.

ded2a42ac1 Use a union instead of casts 
Same intended semantics, no casts.

Limitation: this doesn't work on architectures where
sizeof(uintptr_t) < sizeof(void*), which is somewhat weird but possible if
pointers contain redundant information.

49d7ddf7f3 Serializing a context does not save the user data 
The user data is typically a pointer to a data structure or a handle which
may no longer be valid after the session is restored. If the user data needs
to be preserved, let the application do it. This way, it is a conscious
decision for the application to save/restore either the pointer/handle
itself or the object it refers to.

69477b5706 Add a field for application data to TLS structures 
In structure types that are passed to user callbacks, add a field that the
library won't ever care about. The application can use this field to either
identify an instance of the structure with a handle, or store a pointer to
extra data.
