It is really fast now

It was introduced in commit eeb2cb05 along with the -F type=
change. Also fixed a typo in the name of the magic filename=
parameter. Tweaked tests 39 and 173 to better test this path.

The numerical value passed to CURLOPT_RESUME_FROM for FTP uploads is
interpreted and used as position where to resume the _reading_ of the
local file and it will "blindly" append that data on the remote
file. This was certainly not clear in the docs previously.

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

The -F option allows some custom parameters within the given string, and
those strings are separated with semicolons. You can for example specify
"name=daniel;type=text/plain" to set content-type for the
field. However, the use of semicolons like that made it not work fine if
you specified one within the content-type, like for:
"name=daniel;type=text/plain;charset=UTF-8"
... as the second one would be seen as a separator and "charset" is no
parameter curl knows anything about so it was just silently discarded.

The new logic now checks if the semicolon and following keyword looks
like a parameter it knows about and if it isn't it is assumed to be
meant to be used within the content-type string itself.

I modified test case 186 to verify that this works as intended.

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.

It seems that its time to look at some better ideas for the win32
non-configure builds; probably a prebuild target which copies
config-win32.h to curl_config.h and appends also then feature
defines like USE_ARES.

It was complaining about the '=>' operator, introduced in e3fc0d5e.

The 66 bytes checked are those 38 bytes with the chunked encoding
headers added: 8+8+10+35+5 = 66

The three-letter words become 8 bytes on the wire because they are sent
like: "3\r\none\r\n"

... and there's the trailing 5 bytes write after the four lines since
the final chunk is sent (which is "0\r\n\r\n").

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.

"1.13 curl's ECCN number" is a new section mostly made up from
Alessandro Vesely's very informative ML post on the subject:

Add a call to Curl_pgrsSetUploadSize in this case valided by a test

In some situations, libtool will change directories and perform
a link step before executing the libtest test app. Since
LD_PRELOAD is in effect for this entire process, the path to the
binary must be absolute so it will be valid no matter in which
directory the app is running.

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.

This allows a test to be run several times in the same test
session even when the -k option is given.

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.

Otherwise, variables from tests could affect the servers
themselves.

Due to the layout of the singletest function there are situations where
it returns before it clears the environment variables that were
especially set for the single specific test case. That could lead to
subsequent tests getting executed with environment variables sticking
around from a previous test which could lead to badness.

This change makes sure to clear all custom variables that may be laying
around from a previous round, before running a test case.
