707ceb88f0 Replaced mbedtls_ssl_safer_memcmp with mbedtls_platform_memcmp
Saves some bytes and mbedtls_platform_memcmp is a bit safer for side channel
attacks.

7f2c3e4034 Remove dependency of ssl_cookie on SHA-224
Cookies are fully opaque so we can change the hash used at any time, it's not
part of the API.

The cookie module handles truncation, so it's simpler to always use SHA-256
rather than check if SHA-224 is available.

e32df087fb Remove individual copies of mbedtls_zeroize()
This commit removes all the static occurrencies of the function
mbedtls_zeroize() in each of the individual .c modules. Instead the
function has been moved to utils.h that is included in each of the
modules.

04965edaa8 Fix resource leak when using mutex and ssl_cookie
When using ssl_cookie with MBEDTLS_THREADING_C, fix a resource leak caused by
initiating a mutex in mbedtls_ssl_cookie_free instead of freeing it.
Raised and fix suggested by lan Gillingham in the mbed TLS forum
Tracked in #771

b5b6af2663 Puts platform time abstraction into its own header
Separates platform time abstraction into it's own header from the
general platform abstraction as both depend on different build options.
(MBEDTLS_PLATFORM_C vs MBEDTLS_HAVE_TIME)

Note from future self: actually md_init_ctx will be re-introduced with the
same signature later, and a new function with the additional argument will be
added.
