add socket/security policies to translate asio -> websocketpp error codes

The reason these were added to the socket policies rather than higher
up is that in some cases translating error codes requires information
from headers and libraries that are not present except when certain
socket policies are being used. For example, SSL/TLS related errors can
only be translated using openssl, which is only pulled in with the TLS
socket policy.
cleans up the handling of TLS related transport errors

Specifically: TLS short read is separated from other TLS errors. Other
TLS errors are also not separated from generic “pass through” errors.

TLS short read is now considered “expected” during socket shutdown and
is not reported as an error.
