Introduce ciphersuite handle type

Browse source 
This commit introduces an internal zero-cost abstraction layer for
SSL ciphersuites: Instead of addressing ciphersuites via pointers
to instances of mbedtls_ssl_ciphersuite_t and accessing their fields
directly, this commit introduces an opaque type

  mbedtls_ssl_ciphersuite_handle_t,

and getter functions

  mbedtls_ssl_suite_get_xxx()

operating on ciphersuite handles.

The role of NULL is played by a new macro constant

  MBEDTLS_SSL_CIPHERSUITE_INVALID_HANDLE

which results of functions returning handles can be checked against.
(For example, when doing a lookup of a ciphersuite from a peer-provided
ciphersuite ID in the per's Hello message).

The getter functions have the validity of the handle as a precondition
and are undefined if the handle is invalid.

So far, there's only one implementation of this abstraction layer, namely

  mbedtls_ssl_ciphersuite_handle_t being mbedtls_ssl_ciphersuite_t const *

and

  getter functions being field accesses.

In subsequent commits, however, the abstraction layer will be useful
to save code in the situation where only a single ciphersuite is enabled.
