* implement certain servicessl functions * ssl: Implement more of SSL connection and abstract it This adds support to non blocking SSL operations and unlink the SSL implementation from the IPC logic. * Rename SslDefaultSocketConnection to SslManagedSocketConnection * Fix regression on Pokemon TV * Address gdkchan's comment * Simplify value read from previous commit * ssl: some changes - Implement builtin certificates parsing and retrieving - Fix issues with SSL version handling - Improve managed SSL socket error handling - Ensure to only return a certificate on DoHandshake when actually requested * Add missing BuiltInCertificateManager initialization call * Address gdkchan's comment * Address Ack's comment Co-authored-by: InvoxiPlayGames <webmaster@invoxiplaygames.uk>
