Fixed IMAP Idle for Windows Build

select in windows cannot be used with non-sockets, use
WaitForMultipleObjects instead.

Update parameter for mailimap_has_extension and mailimap_has_authentication to use const char *

Update mailimap.c

#190  parse response

Added macro LIBETPAN_HAS_MAILIMAP_163_WORKAROUND

Changed ENABLE_163_WORKAROUND to LIBETPAN_HAS_MAILIMAP_163_WORKAROUND

I have added this feature into the mailcore2,  the compiler will ignore this feature if someone compile the new version of mailcore2 without this patch and this macro definition.

Implemented workaround for 163.com servers.

changed parameter name from `imap` to `session`.

changed mailimap's member `complex_command_tag_enabled` to `is_163_workaround_enabled`.

changed 
` int mailimap_is__complex_command_tag_enabled(mailimap * imap); `
` void mailimap_set_complex_command_tag_enabled(mailimap * imap, int enabled);`
to
`int mailimap_is_163_workaround_enabled(mailimap * imap);`
`void mailimap_set_163_workaround_enabled(mailimap * imap, int enabled);`

changed 
` int mailimap_is__complex_command_tag_enabled(mailimap * imap); `
` void mailimap_set_complex_command_tag_enabled(mailimap * imap, int enabled);`
to
`int mailimap_is_163_workaround_enabled(mailimap * imap);`
`void mailimap_set_163_workaround_enabled(mailimap * imap, int enabled);`

Add some of the headers in the vcproj to help finding code in visual stu...

- Reference Readme.md in Visual Studio sln.
- Fixed linker rule against libsasl.lib
- Don't use deprecated __line when possible

163 mail server will reject the command which with a number tag.

Fix IMAP ID send.

Use mailimap_quoted_send rather than mailimap_astring_send when
sending names and values inside mailimap_id_param_send.
This means skipping the "workaround for buggy Courier-IMAP that
does not accept quoted-strings for fields name but prefer atoms"
and instead always sending quoted strings.

RFC 2971 (with reference to RFC 2060) is clear that these fields
may only be quoted strings or literals, not atoms.  Yahoo's server
rejects this command when atoms are sent (and it is correct to do so).

We shouldn't break compat with well-behaving servers as a workaround
for buggy ones, so using quoted strings here is the best choice.

Added MAILSMTP_ERROR_AUTH_TIMEOUT
