was due to a missing fix for the password prompting

"username" will cause libcurl to prompt for password. Bryan Kemp noticed.

test case 136 is added for this

stack. Kjetil Jacobsen reported and verified the fix.

design document specifies. There is still no code inside that uses this.

Return file-error if 550 is returned when trying MDTM

that the output looks better

previously, if you called curl_easy_perform and then set the global dns
cache, the global cache wouldn't be used.  I don't see this really happening
in practice, but this code allows you to do it.

care how many bytes that is readable NOW. Philippe Raoult reported the
bug in 7.10.3-pre3.

situation occurs, which it previously didn't!

This was reptoed by Evan Jordan in bug report #653022.

Also, if ERROR_SYSCALL is returned from SSL_write(), include the errno number
in the error string for easier error detection.

for a bigger buffer and this is indeed badness for us. Making this work
on both old and new glibc versions require an ugly loop that in its worse
form cause 45 bad loops when using the correct glibc and a non-resolving
host name... :-/

We want a better fix. Badly.

multi interface works with file:// URLs fine (previously it crashed). This
won't make it work on Windows though...

regular transfer process. This required some new tweaks, like for example
we need to be able to tell the tranfer loop to not chunky-encode uploads
while we're transferring the rest of the request...

read callback, and thus won't put a lot of stress on the request sending
code (which currently does an ugly loop).

connectdata struct instead, and is no longer modified within the 'set' struct
as previously (which was a really BAAAD thing).

returning back to the select() loop. Consider this a test so far.

complete is now only made for 60 seconds and if no data was received during
those 60 seconds, we store a special error message (preparing to make this
a special error code) as this most likely means that the control connection
has died while we were transferring data.

proper CURLcode. The default timeout for reading one response is now also
possible to change while running.
