After curl_multi_wait() returns, this test checked that we got exactly
one file descriptor told to read from, but we cannot be sure that is
true. curl_multi_wait() will sometimes return earlier without any file
descriptor to handle, just just because it is a suitable time to call
*perform().
This problem showed up with commit 29bf0598.

If an ipv6-address is provided to CONNECT, the last hexadecimal group in
the address will be used as the test number! For example the address
"[1234::ff]" would be treated as test case 255.
commit 29bf0598aa introduced a problem when the "internal" timeout is
prefered to the given if shorter, as it didn't consider the case where
-1 was returned. Now the internal timeout is only considered if not -1.

Also added a (correctly-escaped) backslash to the autoexec.bat
example file and a new Windows character device name with
a colon as examples of other characters that are special
and potentially dangerous (this reverts and reworks commit
7d8d2a54).
If the multi handle's pending timeout is less than what is passed into
this function, it will now opt to use the shorter time anyway since it
is a very good hint that the handle wants to process something in a
shorter time than what otherwise would happen.
curl_multi_wait.3 was updated accordingly to clarify
This is the reason for bug #1224

When sending the HTTP Authorization: header for digest, the user name
needs to be escaped if it contains a double-quote or backslash.

We found that in specific cases if the connection is abruptly closed,
the underlying socket is listed in a close_wait state. We continue to
call the curl_multi_perform, curl_mutli_fdset etc. None of these APIs
report the socket closed / connection finished. Since we have cases
where the multi connection is only used once, this can pose a problem
for us. I've read that if another connection was to come in, curl would
see the socket as bad and attempt to close it at that time -
unfortunately, this does not work for us.
I found that in specific situations, if SSL_write returns 0, curl did
not recognize the socket as closed (or errored out) and did not report
it to the application. I believe we need to change the code slightly, to
check if ssl_write returns 0. If so, treat it as an error - the same as
a negative return code.
For OpenSSL - the ssl_write documentation is here:
http://www.openssl.org/docs/ssl/SSL_write.html
1 - don't skip host names with a colon in them in an attempt to bail out
on HTTP headers in the cookie file parser. It was only a shortcut anyway
and trying to parse a file with HTTP headers will still be handled, only
slightly slower.
2 - don't skip domain names based on number of dots. The original
netscape cookie spec had this oddity mentioned and while our code
decreased the check to only check for two, the existing cookie spec has
no such dot counting required.

I found a bug which cURL sends cookies to the path not to aim at.
For example:
- cURL sends a request to http://example.fake/hoge/
- server returns cookie which with path=/hoge;
the point is there is NOT the '/' end of path string.
- cURL sends a request to http://example.fake/hogege/ with the cookie.
The reason for this old "feature" is because that behavior is what is
described in the original netscape cookie spec:
http://curl.haxx.se/rfc/cookie_spec.html
The current cookie spec (RFC6265) clarifies the situation:
http://tools.ietf.org/html/rfc6265#section-5.2.4
This reverts commit 8ec2cb5544.
We don't have any code anywhere in libcurl (or the curl tool) that use
wcsdup so there's no such memory use to track. It seems to cause mild
problems with the Borland compiler though that we may avoid by reverting
this change again.
