CURLMOPT_TIMERFUNCTION callback option.

  when CURLM_CALL_MULTI_PERFORM is returned from curl_multi_socket*/perform,
  to make applications using only curl_multi_socket() to properly function
  when adding easy handles "on the fly". Bug report and test app provided by
  Michael Wallner.

for every year is giving us too many files! I also split out the changes
from 2006 from CHANGES to CHANGES.0 now.

the default port numbers, allowing more than one test suite to run
simultaneously on the same host.

since it then inits libgcrypt and libgcrypt is being evil and EXITS the
application if it fails to get a fine random seed. That's really not a nice
thing to do by a library.

been removed from a multi handle, and then fixed another flaw that prevented
curl_easy_duphandle() to work even after the first fix - the handle was
still marked as using the multi interface.

was 16385 bytes (16K+1) and it turned out we didn't properly always "suck
out" all data from libssh2. The effect being that libcurl would hang on the
socket waiting for data when libssh2 had in fact already read it all...

the CURLOPT_RESUME_FROM or CURLOPT_RANGE options and an existing connection
in the connection cache is closed to make room for the new one when you call
curl_easy_perform(). It would then wrongly free range-related data in the
connection close funtion.

can/will be used as it then makes the common cases save 16KB of data for each
easy handle that isn't used for pipelining.

identifying a double-free problem in the SSL-dealing layer, telling GnuTLS to
free NULL credentials on closedown after a failure and a bad #ifdef for NSS
when closing down SSL.

  Curl_socket_ready(), Curl_poll() and Curl_select() when these are called
  with a zero timeout or a timeout value indicating a blocking call should
  be performed.

  These unnecessary calls to gettimeofday() got introduced in 7.16.2 when
  fixing 'timeout would restart when signal caught while awaiting socket
  events' on 20 March 2007.

- Move some loop breaking logic from the while clause into the loop,
  avoiding compiler warning 'assignment within conditional expression'

  per second.

  function that deprecates the curl_multi_socket() function. Using the new
  function the application tell libcurl what action that was found in the
  socket that it passes in. This gives a significant performance boost as it
  allows libcurl to avoid a call to poll()/select() for every call to
  curl_multi_socket*().

of a new host on the net with the same silly domain the test was using
for a host which was supposed not to exist.

name longer than the name field of the ifreq struct (typically 6 bytes), as
then it wouldn't close the used dummy socket.

easy handles are added to a multi handle, by avoiding the looping over all
the handles to find which one to remove.

by letting configure check for setmode and ifdef on HAVE_SETMODE. NOTE: non-
configure platforms that havve setmode() needs their hard-coded config.h files
fixed. I fixed the src/config-win32.h.

and added tests 290 and 291 to check.

uses poll() when a fine poll() is available, so now libcurl can be
built without select() support at all if a fine poll() is available.

  A left-over bug from the February 21 fix.

test case 288 to verify it.

before resorting to the kill -9 hammer.

Added test harness infrastructure to support scp/sftp tests, using
OpenSSH as the server.

plus made --pass work on an SSH private key as well.
