imap: support PREAUTH
It is a defined possible greeting at server startup that means the
connection is already authenticated. See
https://tools.ietf.org/html/rfc3501#section-7.1.4

Test 846 added to verify.

Fixes #1818
Closes #1820

75cd7fd667 imap: Fixed incorrect fallback to clear text authentication
If a specific SASL authentication mechanism was requested by the user
as part of the login options but wasn't supported by the server then
curl would fallback to clear text, when it shouldn't, rather than
reporting "No known authentication mechanisms supported" as the POP3
and SMTP protocols do.

7de4cc35f8 email: Added initial support for cancelling authentication
Should a client application fail to decode an authentication message
received from a server, or not support any of the parameters given by
the server in the message, then the authentication phrase should be
cancelled gracefully by the client rather than simply terminating the
connection.

The authentication phrase should be cancelled by simply sending a '*'
to the server, in response to erroneous data being received, as per
RFC-3501, RFC-4954 and RFC-5034.

This patch adds the necessary state machine constants and appropriate
response handlers in order to add this functionality for the CRAM-MD5,
DIGEST-MD5 and NTLM authentication mechanisms.

34122800b8 imap: added basic SASL XOAUTH2 support
Added the ability to use an XOAUTH2 bearer token [RFC6750] with IMAP for
authentication using RFC6749 "OAuth 2.0 Authorization Framework".

The bearer token is expected to be valid for the user specified in
conn->user. If CURLOPT_XOAUTH2_BEARER is defined and the connection has
an advertised auth mechanism of "XOAUTH2", the user and access token are
formatted as a base64 encoded string and sent to the server as
"A001 AUTHENTICATE XOAUTH2 <bearer token>".

974c663471 imap: Introduced FETCH_FINAL state for processing final fetch responses
A typical FETCH response can be broken down into four parts:

  1) "* <uid> FETCH (<what> {<size>}\r\n", using continuation syntax
  2) <size> bytes of the actual message
  3) ")\r\n", finishing the untagged response
  4) "<tag> OK ...", finishing the command

Part 1 is read in imap_fetch_resp(), part 2 is consumed in the PERFORM
phase by the transfer subsystem, parts 3 and 4 are currently ignored.

Removed this pointer to a downloaded bytes counter because it was set in

the count in (k->bytecount), effectively making the code in transfer.c
"*k->bytecountp = k->bytecount" a no-op.

As a unique identifier should be generated for each command the string
generation is based on the connection id and the incrementing command
id.

b4270a9af1 imap: Fixed no known authentication mechanism when fallback is required
Fixed an issue where (lib)curl is compiled without support for a
supported challenge-response based SASL authentication mechanism, such
as CRAM-MD5 or NTLM, the server doesn't support the LOGIN or PLAIN
mechanisms and (lib)curl doesn't fallback to Clear Text authentication.

Note: In order to fallback to Clear Text authentication properly this
fix adds support for the LOGINDISABLED server capability.
