The correctly extracted errno contents were mistakenly overwritten by a newer
value that wasn't the correct error value.

The script works exactly same as the Perl one except for one thing:
when the text descriptions generated with openssl are included then
the md5 fingerprints are missing; seems openssl has either a bug or
a feature which prints the md5 fingerprint output to stdout instead
of writing them to specified file; this script could here do the same
as what the Perl scripr does (redirect stdout into file) but this
makes the script take up double the time because it needs to launch
cmd.exe 140 times (fo each openssl call). So I think for now we just
ommit the md5 fingerprints, and see if openssl will be fixed.

I fell over this bug report that mentioned that libcurl could wrongly
send more than one complete messages at the end of a transfer. Reading
the code confirmed this, so I've added a new multi state to make it not
happen. The mentioned bug report was made by Brad Jorsch but is (oddly
enough) filed in Debian's bug tracker for the "wmweather+" tool.

There's an error in http_negotiation.c where a mistake is using only
userpwd even for proxy requests. Ludek provided a patch, but I decided
to write the fix slightly different using his patch as inspiration.

When detecting that the send or recv speed, the multi interface changes
state to TOOFAST and previously there was no timeout set that would
force a recheck but it would rely on the application to somehow call
libcurl anyway. This now sets a timeout for a suitable future time to
check again if the average transfer speed is then below the threshold
again.

Curl_expire() is now expanded to hold a list of timeouts for each easy
handle. Only the closest in time will be the one used as the primary
timeout for the handle and will be used for the splay tree (which sorts
and lists all handles within the multi handle).

When the main timeout has triggered/expired, the next timeout in time
that is kept in the list will be moved to the main timeout position and
used as the key to splay with. This way, all timeouts that are set with
Curl_expire() internally will end up as a proper timeout. Previously any
Curl_expire() that set a _later_ timeout than what was already set was
just silently ignored and thus missed.

Setting Curl_expire() with timeout 0 (zero) will cancel all previously
added timeouts.

Corrects known bug #62.

When we specify the "insert after" entry as NULL, this function now
inserts the new entry first in the list.

Instead of looping over all attached easy handles, this now keeps a list
of messages in the multi handle. It allows curl_multi_info_read() to
perform O(1) no matter how many easy handles that are handled. This is
of importance since this function may be polled very frequently by apps
using the multi interface.

warning: conversion to 'long int' from 'time_t' may alter its value

... on win64 when time_t is 64bit and long is 32bit.

When the progress callback is called during the TCP connection, an error
return would accidentally not abort the operation as intended but would
instead be counted as a failure to connect to that particular IP and
libcurl would just continue to try the next. I made singleipconnect()
and trynextip() return CURLcode properly.

Added bonus: it corrected the error code for bad --interface usages,
like tested in test 1084 and test 1085.

Final fix (hopefully!) for dll wlink loader;
prefer faster internal rm if available.

Added the -br switch to dynamic builds which fixes the issue I saw
with curl's --version output. Added debug info and symfile for debug
builds to linker opts. Added DLL loader for wlink back, but this time
dependend on wlink version.

The var %MAKEFLAGS is only set in 3 cases: if set as environment
var or as macro definition from commandline, and either with the
-u or -ms switch. Since all these cases are unlikely for the average
user it should be safe to only test if %MAKEFLAGS is defined; this
has the benefit that now all other switches can be used again in
addition to the -u which was formerly not possible.

Curl_llist_init is never used outside of llist.c and thus it should be
static. I also removed the protos for Curl_llist_insert_prev and
Curl_llist_remove_next which are functions we removed from llist.c ages
ago.

Test 563 is enabled now and verifies that the combo FTP type=A URL,
CURLOPT_PORT set and proxy work fine. As a bonus I managed to remove the
somewhat odd FTP check in parse_remote_port() and instead converted it
to a better and more generic 'slash_removed' struct field. Checking the
->protocol field isn't right since when an FTP:// URL is sent over a
HTTP proxy, the protocol is HTTP but the URL was handled by the FTP code
and thus slash_removed is set TRUE for this case.

The struct used for storing the message for a completed transfer is now
no longer allocated separatly but is kept within the main struct kept
for each easy handle so that we avoid one malloc (and the subsequent
free).

When libcurl internally decided to wait for a 100-continue header, there
was no call to the timeout function so there was no timeout callback
called when the multi_socket API was used and thus applications became
either completely wrong or at least ineffecient depending on how they
handled the situation. We now set a timeout to get triggered.

For now removed the .autodepend directive until I've figured out
which of my changes broke it again.

libssh2 1.2.6 and later handle >32bit file sizes properly even on 32bit
architectures and we make sure to use that ability.

Simply because the TCP might be connected already we cannot skip the
proxy connect procedure. We need to be careful to not overload more
meaning to the bits.tcpconnect field like this.

With this fix, SOCKS proxies work again when the multi interface is
used. I believe this regression was added with commit 4b351d01,
released as 7.20.1.

Left todo: add a test case that verifies this functionality that
prevents us from breaking it again in the future!

There is an implicit conversion from "unsigned long" to "long";
rounding, sign extension, or loss of accuracy may result.
