261602cb34 Uniformize bounds checks using new macro
This commit uses the previously defined macro to uniformize
bounds checks in several places. It also adds bounds checks to
the ClientHello writing function that were previously missing.
Also, the functions adding extensions to the ClientHello message
can now fail if the buffer is too small or a different error
condition occurs, and moreover they take an additional buffer
end parameter to free them from the assumption that one is
writing to the default output buffer.

73c616bdc1 Put includes in alphabetical order
The library style is to start with the includes corresponding to the
current module and then the rest in alphabetical order. Some modules
have several header files (eg. ssl_internal.h).

The recently added error.h includes did not respect this convention and
this commit restores it. In some cases this is not possible just by
moving the error.h declarations. This commit fixes the pre-existing
order in these instances too.

865b3ebf84 Initialize return values to an error
Initializing the return values to an error is best practice and makes
the library more robust against programmer errors.

a3e7c65101 Move session save/load function to ssl_tls.c
This finishes making these functions public. Next step is to get them tested,
but there's currently a blocker for that, see next commit (and the commit
after it for tests).

c5fcbb33c0 Add peer CRT digest to session tickets
This commit changes the format of session tickets to include
the digest of the peer's CRT if MBEDTLS_SSL_KEEP_PEER_CERTIFICATE
is disabled.

This commit does not yet remove the peer CRT itself.

c470b6b021 Merge development commit 8e76332 into development-psa
Additional changes to temporarily enable running tests:
ssl_srv.c and test_suite_ecdh use mbedtls_ecp_group_load instead of
mbedtls_ecdh_setup
test_suite_ctr_drbg uses mbedtls_ctr_drbg_update instead of 
mbedtls_ctr_drbg_update_ret

679d8ceb13 Use PSA-based ciphers for SSL ticket protection
This commit modifies the default SSL ticket implementation
from `library/ssl_ticket.c` to use PSA-based cipher context
for ticket creation and parsing.

As in mbedtls_ssl_derive_keys() adapted in an earlier commit,
we allow fallback to the ordinary mbedtls_cipher_setup()
if the provided cipher is not known. We do this even though
we always call mbedtls_ssl_ticket_setup() with AES-GCM
in our own code since this function is public and might
be used with other ciphers by users.

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.

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.
