This has the following optimization potentials which are also applied.
- crypto: only one HMAC context is required
- crypto: integrate last iteration into loop
- hmac: remove dtls_hmac_new()/_free()/_storage_init() as dtls_hmac_new()
now only is used in tests

For ESP-IDF, use the ESP-IDF sha256 hash implementation to save on code
size.

This moves the mapping of function names and types for sha256
calculations into a single conditional section at the beginning
of the file in order to minimize the number of pre-processor
conditionals spread throughout the code.

For platforms other than Contiki, dtls_hmac_storage_init() was
defined inline in hmac.h which cluttered the interface.

Fixes dtls_config.h not visible in headers
Include dtls_config.h in tinydtls.h and include tinydtls.h in all necessary
headers.
Remaining headers do not use 'ifdef', but they may require it too.

this change is for resolving |sha2| symbol-conflict in using
|tinydtls| with other crypto modules. this symbol-conflict could
occur on the |tinydtls|-deployed systems with using |OpenSSL| or
|OpenSSL|-like, which has another |SHA| symbols.
In case of |iotivity-tinydtls|, the conflict occurs between
|iotivity-tinydtls| and the deployed |crypto| library, which has
also another |SHA|.
