When doing multi-part formposts, libcurl used a pseudo-random value that
was seeded with time(). This turns out to be bad for users who formpost
data that is provided with users who then can guess how the boundary
string will look like and then they can forge a different formpost part
and trick the receiver.
My advice to such implementors is (still even after this change) to not
rely on the boundary strings being cryptographically strong. Fix your
code and logic to not depend on them that much!
I moved the Curl_rand() function into the sslgen.c source file now to be
able to take advantage of the SSL library's random function if it
provides one. If not, try to use the RANDOM_FILE for seeding and as a
last resort keep the old logic, just modified to also add microseconds
which makes it harder to properly guess the exact seed.
The formboundary() function in formdata.c is now using 64 bit entropy
for the boundary and therefore the string of dashes was reduced by 4
letters and there are 16 hex digits following it. The total length is
thus still the same.

RFC3986 details how a path part passed in as part of a URI should be
"cleaned" from dot sequences before getting used. The described
algorithm is now implemented in lib/dotdot.c with the accompanied test
case in test 1395.

The initial fix to only compare full path names were done in commit
04f52e9b4d but found out to be incomplete. This takes should make the
change more complete and there's now two additional tests to verify
(test 31 and 62).
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.
When sending the HTTP Authorization: header for digest, the user name
needs to be escaped if it contains a double-quote or backslash.

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.

If the mail sent during the transfer contains a terminating <CRLF> then
we should not send the first <CRLF> of the EOB as specified in RFC-5321.
Additionally don't send the <CRLF> if there is "no mail data" as the
DATA command already includes it.
The emails that are sent to the server during these tests were
incorrectly formatted as they contained one or more LF terminated lines
rather than being CRLF terminated as per Section 2.3.7 of RFC-2821.
This wasn't a problem for the test suite as the <stdin> data matched the
<upload> data but anyone using these tests as reference would be sending
incorrect data to a server.
Updated test903 and test904 following the addition of CURLOPT_SASL_IR
as the default behaviour of SMTP AUTH responses is now to not include
the initial response. New tests with --sasl-ir support to follow.
When connecting back to an FTP server after having sent PASV/EPSV,
libcurl sometimes didn't use the proxy properly even though the proxy
was used for the initial connect.
The function wrongly checked for the CURLOPT_PROXY variable to be set,
which made it act wrongly if the proxy information was set with an
environment variable.
Added test case 711 to verify (based on 707 which uses --socks5). Also
added test712 to verify another variation of setting the proxy: with
--proxy socks5://

I couldn't figure out why the host key logic isn't working, but having
it set to yes prevents my SSH-based test cases to run. I also don't see
a strong need to use strict host key checking on this test server.
So I disabled it.
