c70b982056 OID functionality moved to a separate module. 
A new OID module has been created that contains the main OID searching
functionality based on type-dependent arrays. A base type is used to
contain the basic values (oid_descriptor_t) and that type is extended to
contain type specific information (like a pk_alg_t).

As a result the rsa sign and verify function prototypes have changed. They
now expect a md_type_t identifier instead of the removed RSA_SIG_XXX
defines.

All OID definitions have been moved to oid.h
All OID matching code is in the OID module.

The RSA PKCS#1 functions cleaned up as a result and adapted to use the
MD layer.

The SSL layer cleanup up as a result and adapted to use the MD layer.

The X509 parser cleaned up and matches OIDs in certificates with new
module and adapted to use the MD layer.

The X509 writer cleaned up and adapted to use the MD layer.

3d2dc0f8e5 Corrected GCM counter incrementation to use only 32-bits instead of 128-bits 
Using 32-bits has the possibility to overwrite the IV in the first 12
bytes of the Y variable.

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.

Enable a dummy error function to make use of error_strerror() in

Disable if you run into name conflicts and want to really remove the
error_strerror()
