Manuel Pégourié-Gonnard b747c6cf9b Add basic first tests for MTU setting 
For now, just check that it causes us to fragment. More tests are coming in
follow-up commits to ensure we respect the exact value set, including when
renegotiating.

Manuel Pégourié-Gonnard 2cb17e201b Make handshake fragmentation follow max_frag_len 
Note: no interop tests in ssl-opt.sh for now, as some of them make us run into
bugs in (the CI's default versions of) OpenSSL and GnuTLS, so interop tests
will be added later once the situation is clarified. <- TODO

Manuel Pégourié-Gonnard 87a346f64e Always save flight first, (re)send later 
This will allow fragmentation to always happen in the same place, always from
a buffer distinct from ssl->out_msg, and with the same way of resuming after
returning WANT_WRITE

Manuel Pégourié-Gonnard 9c3a8caa92 Clarify code a bit in write_handshake_msg() 
- take advantage of the fact that we're only called for first send
- put all sanity checks at the top
- rename and constify shortcut variables
- improve comments

Hanno Becker 5b559ac7ab Fix mbedtls_ssl_get_record_expansion() for ChaChaPoly and CBC 
`mbedtls_ssl_get_record_expansion()` is supposed to return the maximum
difference between the size of a protected record and the size of the
encapsulated plaintext.

It had the following two bugs:
(1) It did not consider the new ChaChaPoly ciphersuites, returning
    the error code #MBEDTLS_ERR_SSL_INTERNAL_ERROR in this case.
(2) It did not correctly estimate the maximum record expansion in case
    of CBC ciphersuites in (D)TLS versions 1.1 and higher, in which
    case the ciphertext is prefixed by an explicit IV.

This commit fixes both bugs.

Ron Eldor 1b9b217abf enforce input and output of ccm selftest on stack 
In `mbedtls_ccm_self_test()`, enforce input and output
buffers sent to the ccm API to be contigous and aligned,
by copying the test vectors to buffers on the stack.

Simon Butcher 5f26b11ffa Change test dependencies to RC4 from DES 
Some tests were dependent on DES yet actually used RC4. Likely a copy and paste
error. This change fixes them.

Simon Butcher c796573487 Add Chacha dependency to the stream cipher field 
When MBEDTLS_ARC4_C and MBEDTLS_CIPHER_NULL_CIPHER were disabled, the stream
cipher function wasn't being include in the cipher struct, yet Chacha20 requires
it.

Angus Gratton 608a487b9c Fix memory leak in ecp_mul_comb() if ecp_precompute_comb() fails 
In ecp_mul_comb(), if (!p_eq_g && grp->T == NULL) and then ecp_precompute_comb() fails (which can
happen due to OOM), then the new array of points T will be leaked (as it's newly allocated, but
hasn't been asigned to grp->T yet).

Symptom was a memory leak in ECDHE key exchange under low memory conditions.
