* Do not use ApplicationProtocols with SSL. (issue #1352)
* Updated GMail, Yahoo, and Outlook.com certificates.
* Lazy-initialize MessageSummary.Keywords. This reduces memory usage when the client isn't requesting Flags/Keywords.
* Hard-cache some IMAP FETCH-related tokens in order to relieve GC pressure for commands like FETCH where there can be a LOT of responses containing the same tokens over and over again.
* Converted some IMAP async Task methods to use ValueTask to reduce GC pressure.
* Reduced string allocations in the IMAP logic by avoiding use of ToUpperInvariant().
* Added non-async implementations for ImapStream APIs to be used by the synchronous public APIs to avoid some async overhead.
* Reduce MemoryStream (and thus byte[]) allocations by using a new ByteArrayBuilder.
* Rewrote the IMAP CAPABILITY parser to avoid allocating strings.
* Fixed some cases where IMAP NIL tokens were not compared case insensitively.
* Always include the VERSION block in NTLM messages. (issue #1340)
* Target .NET Framework v4.6.1 instead of v4.6 to match the changes in MimeKit.
* Capture the Socket timeout value in Read/WriteAsync() to have it in case of exceptions. (issue #1327)
