Previously it only compared credentials if the requested needle
connection wasn't using a proxy. This caused NTLM authentication
failures when using proxies as the authentication code wasn't send on
the connection where the challenge arrived.
Added test 1215 to verify: NTLM server authentication through a proxy
(This is a modified copy of test 67)
Since qsort implementations vary with regards to handling the order
of similiar elements, this change makes the internal sort function
more deterministic by comparing path length first, then domain length
and finally the cookie name. Spotted with testcase 62 on Windows.
WINSOCK only:
Since FD_CLOSE is only signaled once, it may trigger at the same
time as FD_READ. Data actually being available makes it impossible
to detect that the connection was closed by checking that recv returns
zero. Another recv attempt could block the connection if it was
not closed. This workaround abuses exceptfds in conjunction with
readfds to signal that the connection has actually closed.
Since commit 57aeabcc1a, it handles errors on the control connection
while waiting for the data connection better.
Test 591 and 592 are updated accordingly.
When doing PORT and upload (STOR), this function needs to extract the
file descriptor for both connections so that it will respond immediately
when the server eventually connects back.
This flaw caused active connections to become unnecessary slow but they
would still often work due to the normal polling on a timeout. The bug
also would not occur if the server connected back very fast, like when
testing on local networks.

I am using curl_easy_setopt(CURLOPT_INTERFACE, "if!something") to force
transfers to use a particular interface but the transfer fails with
CURLE_INTERFACE_FAILED, "Failed binding local connection end" if the
interface I specify has no IPv6 address. The cause is as follows:
The remote hostname resolves successfully and has an IPv6 address and an
IPv4 address.
cURL attempts to connect to the IPv6 address first.
bindlocal (in lib/connect.c) fails because Curl_if2ip cannot find an
IPv6 address on the interface.
This is a fatal error in singleipconnect()
This change will make cURL try the next IP address in the list.
Also included are two changes related to IPv6 address scope:
- Filter the choice of address in Curl_if2ip to only consider addresses
with the same scope ID as the connection address (mismatched scope for
local and remote address does not result in a working connection).
- bindlocal was ignoring the scope ID of addresses returned by
Curl_if2ip . Now it uses them.

This workaround fixes an issue on MinGW/Msys regarding the Perl
testsuite scripts not being able to signal or control the server
processes. The MinGW Perl runtime only sees the Msys processes and
their corresponding PIDs, but sockfilt (and other servers) wrote the
Windows PID into their PID-files. Since this PID is useless to the
testsuite, the write_pidfile function was changed to search for the
Msys PID and write that into the PID-file.
At some point recently we lost the default value for the easy handle's
connection cache, and this change puts it back to 5 - which is the
former default value and it is documented in the curl_easy_setopt.3 man
page.
The new read and write wrapper functions support reading from stdin
and writing to stdout/stderr on Windows by using the appropriate
Windows API functions and data types.
The Microsoft knowledge-base article
http://support.microsoft.com/kb/823764 describes how to use SNDBUF to
overcome a performance shortcoming in winsock, but it doesn't apply to
Windows Vista and later versions. If the described SNDBUF magic is
applied when running on those more recent Windows versions, it seems to
instead have the reversed effect in many cases and thus make libcurl
perform less good on those systems.
This fix thus adds a run-time version-check that does the SNDBUF magic
conditionally depending if it is deemed necessary or not.
