* Added information about the verify and expand commands to
CURLOPT_MAIL_RCPT.
* Reworked CURLOPT_CUSTOMREQUEST section, adding information about IMAP
and SMTP custom commands.
It turns out that some of the constants necessary to make this feature
work are missing from Snow Leopard's Security framework even though
they are defined in the headers.
Bug: http://curl.haxx.se/mail/lib-2013-11/0076.html
Reported by: myriachan
Rather than set the authentication options as part of the login details
specified in the URL, or via the older CURLOPT_USERPWD option, added a
new libcurl option to allow the login options to be set separately.

Okay. I've tested the following with MSVC and MingW. htttput.c now
simply uses stat():
CURL_SSLVERSION_TLSv1_0, CURL_SSLVERSION_TLSv1_1,
CURL_SSLVERSION_TLSv1_2 enum values are added to force exact TLS version
(CURL_SSLVERSION_TLSv1 means TLS 1.x).
axTLS:
axTLS only supports TLS 1.0 and 1.1 but it cannot be set that only one
of these should be used, so we don't allow the new enum values.
darwinssl:
Added support for the new enum values.
SChannel:
Added support for the new enum values.
CyaSSL:
Added support for the new enum values.
Bug: The original CURL_SSLVERSION_TLSv1 value enables only TLS 1.0 (it
did the same before this commit), because CyaSSL cannot be configured to
use TLS 1.0-1.2.
GSKit:
GSKit doesn't seem to support TLS 1.1 and TLS 1.2, so we do not allow
those values.
Bugfix: There was a typo that caused wrong SSL versions to be passed to
GSKit.
NSS:
TLS minor version cannot be set, so we don't allow the new enum values.
QsoSSL:
TLS minor version cannot be set, so we don't allow the new enum values.
OpenSSL:
Added support for the new enum values.
Bugfix: The original CURL_SSLVERSION_TLSv1 value enabled only TLS 1.0,
now it enables 1.0-1.2.
Command-line tool:
Added command line options for the new values.
The option '--bearer' might be slightly ambiguous in name. It doesn't
create any conflict that I am aware of at the moment, however, OAUTH v2
is not the only authentication mechanism which uses "bearer" tokens.
Reported-by: Kyle L. Huff
URL: http://curl.haxx.se/mail/lib-2013-10/0064.html
Added missing information, from curl 7.31.0, regarding the use of the
optional login options that may be specified as part of --user.
For example:
--user 'user:password;auth=NTLM' in IMAP, POP3 and SMTP protocols.
Added the ability to use an XOAUTH2 bearer token [RFC6750] with POP3 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
"AUTH XOAUTH2 <bearer token>".
