earlephilhower Move BearSSLHelpers into BearSSL namespace (#5315)
BearSSLX509List, BearSSLSession, BearSSLPublicKey, and BearSSLPrivateKey
were all in the global namespace and not in the BearSSL:: one, due to an
oversight when they were originally created.  Move them to the proper
namespace with the following mapping:
    BearSSLX509List => BearSSL::X509List
    BearSSLSession => BearSSL::Session
    BearSSLPublicKey => BearSSL::PublicKey
    BearSSLPrivateKey => BearSSL::PrivateKey
