Darryl Green 608e091d9a Add pre Visual Studio 2015 support to psa_constant_names
snprintf was only added in Visual Studio 2015. This adds support
for building using Visual Studio versions prior to 2015.

This implementation of snprintf has been taken from platform.c

Gilles Peskine daea26f70f Correct and simplify block-based cipher modes
OFB and CFB are streaming modes. XTS is a not a cipher mode but it
doesn't use a separate padding step. This leaves only CBC as a block
cipher mode that needs a padding step.

Since CBC is the only mode that uses a separate padding step, and is
likely to remain the only mode in the future, encode the padding mode
directly in the algorithm constant, rather than building up an
algorithm value from a chaining mode and a padding mode. This greatly
simplifies the interface as well as some parts of the implementation.

Gilles Peskine 029b5d648d New utility program psa/psa_constant_names
Print the symbolic name corresponding to a numerical value.

Supported types: status values, algorithms, elliptic curves,
key types, key usage masks.

The program is partly generated from parsing psa/crypto.h with a few
hard-coded assumptions. This isn't ideal but it works and requires
little machinery.
