48f7a5d724 DHE-PSK based ciphersuite support added and cleaner key exchange based
code selection

The base RFC 4279 DHE-PSK ciphersuites are now supported and added.

The SSL code cuts out code not relevant for defined key exchange methods

d4a56ec6bf Added pre-shared key handling for the client side of SSL / TLS
Client side handling of the pure PSK ciphersuites is now in the base
code.

8f4ddaeea9 Ability to specify allowed ciphersuites based on the protocol version.
The ciphersuites parameter in the ssl_session structure changed from
'int *' to 'int *[4]'.

The new function ssl_set_ciphersuite_for_version() sets specific entries
inside this array. ssl_set_ciphersuite() sets all entries to the same
value.

41c83d3f67 Added Ephemeral Elliptic Curve Diffie Hellman ciphersuites to SSL/TLS
Made all modifications to include Ephemeral Elliptic Curve Diffie
Hellman ciphersuites into the existing SSL/TLS modules. All basic
handling of the ECDHE-ciphersuites (TLS_ECDHE_RSA_WITH_NULL_SHA,
TLS_ECDHE_RSA_WITH_RC4_128_SHA, TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA,
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA)
has been included.

e47b34bdc8 Removed further timing differences during SSL message decryption in ssl_decrypt_buf()
New padding checking is unbiased on correct or incorrect padding and
has no branch prediction timing differences.

The additional MAC checks further straighten out the timing differences.

40865c8e5d Added sending of alert messages in case of decryption failures as per RFC
The flag POLARSSL_SSL_ALERT_MESSAGES switched between enabling and
disabling the sending of alert messages that give adversaries intel
about the result of their action. PolarSSL can still communicate with
other parties if they are disabled, but debugging of issues might be
harder.

d66f070d49 Disable debug messages that can introduce a timing side channel.
Introduced the POLARSSL_SSL_DEBUG_ALL flag to enable all these debug
messages in case somebody does want to see the reason checks fail.

1961b709d8 Added ssl_handshake_step() to allow single stepping the handshake
process

Single stepping the handshake process allows for better support of
non-blocking network stacks and for getting information from specific
handshake messages if wanted.

69e095cc15 - Changed the behaviour of x509parse_parse_crt for permissive parsing. Now returns the number of 'failed certificates' instead of having a switch to enable it.
- As a consequence all error code that were positive were changed. A lot of MALLOC_FAILED and FILE_IO_ERROR error codes added for different modules.
 - Programs and tests were adapted accordingly
