release v2.4.3.1

[dalehenrich]

• [x] @HeSe port of Zinc Web Sockets to GsDevKit.
• [x] Use GsDevKit/Cryptography project.
• [x] add ZnGemServer for GsDevKit/gsApplicationTools Gem Server support.
  • ZnGemServer-based tests for Web Sockets, HTTP and REST.
  • ZnGemServer support for logging to Transcript or Object Log:
  • logToObjectLog
  • logToTranscript
  • plus control over what gets logged:
  • logErrorsOnly
  • logEverything
  • ZnGemServer support for the following ZnServer options:
  • authenticator
  • bindingAddress
  • debugMode
  • delegate
  • maximumEntitySize
  • reader
  • route
  • serverUrl
  • useGzipCompressionAndChunking
• [x] Improved continuation support with ZnTransactionSafeManagingMultiThreadedServer.
  • ZnTransactionSafeManagingMultiThreadedServer is the default Server class for GsDevKit.
  • continuations are snapped off for ZnServer infrastructure errors, Halt, and Breakpoints. This support does not interfere with the continuation support provided for Seaside. Instead it provides you with the the equivalent functionality for non-Seaside servers like Web Socket, REST or simple HTTP servers. Note that remote Breakpoints should not be used until 3.2.4 or later.
  • bugfixes and improved continuation support for SocketStream and SocketStreamSocket classes.
  • TransientValue and TrasientStackValue class used in strategic locations to prevent GsSocket and GsProcess instances from being committed.
• [x] fix potential infinite loop on accept error in SocketStreamSocket (d8b708256f7b6b921db361afe2bf650cb84ecac4), by checking for error from underLying socket accept call
• [x] additional Zinc bug fixes:
  • Issue #36: ObjectLog-based ZnLogListener needed
  • Issue #37: review server stack for GemStone/Seaside
  • Issue #43: Address Johan's issues
  • Issue #46: Missing GsSocket exceptions
  • Issue #47: socket error while snapping off continuation
  • Issue #58: port Zinc-WebSocket packages to GemStone
  • Issue #59: Timeout passed to a ZnClient is ignored while making the connection via the underlying socket
  • Issue #68: NeoJSON loads from master and not from gs_master ?
  • [ ] document ZnGemServer examples

From PR #70:

• [x] ZnManagingMultiThreadedServer is used by default for the classic pre-GemServer ZnServers
• [x] ZnTransactionSafeManagingMultiThreadedServer: shoehorn in object log logging for ZnGemServer object logging
• [x] ZnGemServerManagingMultiThreadedServer major refactoring of the ZnServer methods to take full advantage of ZnNewGemServer
