0be55a0549 Remove MBEDTLS_SSL_AEAD_RANDOM_IV feature 
In a USENIX WOOT '16 paper the authors warn about a security risk
of random Initialisation Vectors (IV) repeating values.

The MBEDTLS_SSL_AEAD_RANDOM_IV feature is affected by this risk and
it isn't compliant with RFC5116. Furthermore, strictly speaking it
is a different cipher suite from the TLS (RFC5246) point of view.

Removing the MBEDTLS_SSL_AEAD_RANDOM_IV feature to resolve the above
problems.

95b303648c Restore P>Q in RSA key generation (#558) 
The PKCS#1 standard says nothing about the relation between P and Q
but many libraries guarantee P>Q and mbed TLS did so too in earlier
versions.

This commit restores this behaviour.

8aa301ba31 Add missing bounds check in X509 DER write funcs 
This patch adds checks in both mbedtls_x509write_crt_der and
mbedtls_x509write_csr_der before the signature is written to buf
using memcpy().

433d4c84b3 Add safety check to sample mutex implementation 
Due to inconsistent freeing strategy in pkparse.c the sample mutex
implementation in threading.c could lead to undefined behaviour by
destroying the same mutex several times.

This fix prevents mutexes from being destroyed several times in the
sample threading implementation.

83f26052bf Fix non compliance SSLv3 in server extension handling. 
The server code parses the client hello extensions even when the
protocol is SSLv3 and this behaviour is non compliant with rfc6101.
Also the server sends extensions in the server hello and omitting
them may prevent interoperability problems.

bb81b4a009 Make ar invocation more portable 
armar doesn't understand the syntax without dash. OTOH, the syntax with dash
is the only one specified by POSIX, and it's accepted by GNU ar, BSD ar (as
bundled with OS X) and armar, so it looks like the most portable syntax.
