This commit removes obsolete comments, dead or no longer useful code, and workarounds for several issues that were present in older compilers that we no longer support. Specifically: - It improves the transaction metadata handling class, simplifying its use and making it less error-prone. - It reduces the footprint of the Serializer class by consolidating code and leveraging templates. - It cleanups the ST* class hierarchy, removing dead code, improving and consolidating code to reduce complexity and code duplication. - It shores up the handling of currency codes and the conversation between 160-bit currency codes and their string representation. - It migrates beast::secure_erase to the ripple namespace and uses a call to OpenSSL_cleanse instead of the custom implementation.
