mk-ca-bundle: detect start of trust section better
Each certificate section of the input certdata.txt file has a trust
section following it with details.
This script failed to detect the start of the trust for at least one
cert[*], which made the script continue pass that section into the next
one where it found an 'untrusted' marker and as a result that certficate
was not included in the output.

examples: use do/while loop for multi examples
It's conceivable that after the first time curl_multi_perform returns,
the outvalue still_running will be 0, but work will have been done. This

we always read pending messages off the multi handle by forcing the
while loop to run at least once.

ftp: active conn, place calling sockopt callback at the end of function
Commit b91d29a28e170c16d65d956db79f2cd3a82372d2 introduces a bug and breaks Curl_closesocket function. sock_accepted flag for the second socket should be tagged as TRUE before the sockopt callback is called because in case the callback returns an error, Curl_closesocket function is going to call the - fclosesocket - callback for the accept()ed socket

ftp: active conn, allow application to set sockopt after accept() call
For active FTP connections, applications may need setting the sockopt after accept() call returns successful. This fix gives a call to the callback registered with CURL_SOCKOPTFUNCTION option.

Applications may use this parameter to distinguish between socket types.

verbose messages: fixed output of hostnames in re-used connections
I suspect this is a regression introduced in commit 207cf150, included
since 7.24.0.
Avoid showing '(nil)' as hostname in verbose output by making sure the
hostname fixup function is called early enough to set the pointers that
are used for this. The name data is set again for each request even for
re-used connections to handle multiple hostnames over the same
connection (like with proxy) or that the casing etc of the host name is
changed between requests (which has proven to be important at least once
in the past).
Test1011 was modified to use a redirect with a re-used a connection
since it then showed the bug and now lo longer does. There's currently
no easy way to have the test suite detect 'nil' texts in verbose ouputs
so no tests will detect if this problem gets reintroduced.

Curl_socket_check: fix return code for timeout
We found a problem with ftp transfer using libcurl (7.23 and 7.25)
inside an application which is receiving unix signals (SIGUSR1,
SIGUSR2...) almost continuously. (Linux 2.4, PowerPC, HAVE_POLL_FINE
defined).
Curl_socket_check() uses poll() to wait for the socket, and retries it
when a signal is received (EINTR). However, if a signal is received and
it also happens that the timeout has been reached, Curl_socket_check()
returns -1 instead of 0 (indicating an error instead of a timeout).
In our case, the result is an aborted connection even before the ftp
banner is received from the server, and a return value of
CURLE_OUT_OF_MEMORY from curl_easy_perform() (Curl_pp_multi_statemach(),
in pingpong.c, actually returns OOM if Curl_socket_check() fails :-)
Funny to debug on a system on which OOM is a possible cause).

Due to WSAPoll bugs, libcurl does not work as intended. When the cURL

the result now is CURLE_OPERATION_TIMEDOUT, /* 28 - the timeout time was
reached */.

Add a polling loop in main to read from more than one socket at once. Add the O_NONBLOCK and
SO_KEEPALIVE flag to all sockets. Note that several loops which used to continue on a return value
of 0 (theoretical since 0 would never be returned without O_NONBLOCK) now break on 0 so that they
won't continue reading until after poll is called again.

Hoist the loop out of get_request, and make sure that it can be reentered when a request is
half-finished.
Note the the req struct used to be re-initialized AFTER reading pipeline data, so now that we
initialize it from the caller we must be careful not to overwrite the pipeline data.
Also we now need to handle the case where the buffer is already full when get_request is called -
previously this never happened as it was always called with an empty buffer and looped until done.
Now get_request is called in a loop, so the next step is to run the loop on a socket only when poll
signals it is readable.
