This gives a smoother rate limitation performance by using
sub-second pauses and also taking the buffer sizes into
account.

TFTP is not a protocol that uses close actions so it should
not be set in that bitmask!

The backtick command which extracts 'git log' lines come with a
newline, so chomp the newline before calling logit(), as the logit
function adds a newline by itself.

'git log --oneline' is a relatively recent Git function. It is
documented to be the same as 'git log --pretty=oneline --abbrev-commit',
so use that instead. It works all the way back to Git 1.5.0.

since c-ares no longer embedded, we must not touch such files
anymore

we show the 5 last git commits if git was proven in use, to help
us see exactly what's being tested

That's the symbol we have or generate in include/curl/curlbuild.h

It should at least help visualize which autobuilds that are
using this script.

Make sure <sys/socket.h> is included if around when testing/using
socklen_t.  Also, disable LDAP if LDAP_H is not found on the system.

Bob Richmond: There's an annoying situation where libcurl will
read new HTTP response data from a socket, then check if it's a
timeout if one is set. If the last packet received constitutes
the end of the response body, libcurl still treats it as a
timeout condition and reports a message like:

"Operation timed out after 3000 milliseconds with 876 out of 876
bytes received"

It should only a timeout if the timer lapsed and we DIDN'T
receive the end of the response body yet.

This commit fixes the cmake build of curl, and cleans up the
cmake code a little.  It removes some commented out code and
some trailing whitespace.  To get curl to build the binary
tree include/curl directory needed to be added to the include
path. Also, SIZEOF_SHORT needed to be added.  A check for the
lack of defines of SIZEOF_* for warnless.c was added.

Christopher Conroy fixed a problem with RTSP and GET_PARAMETER
reported to us by Massimo Callegari. There's a new test case 572
that verifies this now.

Test coverage included. Thanks to Massimo Callegari for the bug report

In order to get back on track, I've removed all the plans for
stuff I had in the queue. I will instead focus on fixing bugs and
relying on that people who truly want things added will come back
on the mailing list and nag and provide patches.

7.20.1 should be possible to release in April 2010

c-ares is now hosted entirely separate from the curl project
see http://c-ares.haxx.se/ for all details concerning c-ares,
its source repository and more.

Kenny To filed the bug report #2963679 with patch to fix a
problem he experienced with doing multi interface HTTP POST over
a proxy using PROXYTUNNEL. He found a case where it would connect
fine but bits.tcpconnect was not set correct so libcurl didn't
work properly.

I ran it now successfully and it helped to pinpoint a libssh2
memory leak!

Akos Pasztory filed debian bug report #572276
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=572276
mentioning a problem with a resource that returns chunked-encoded
_and_ with a Content-Length and libcurl failed to properly ignore
the latter information.

Hauke Duden provided an example program that made the multi
interface crash.  His example simply used the multi interface and
did first one FTP transfer and after completion it used a second
easy handle and did another FTP transfer on the same FTP server.

This triggered a bug in the "delayed easy handle kill" system
that curl uses: when an FTP connection is left alive it must keep
an easy handle around internally - only for the purpose of having
an easy handle when it later disconnects it. The code assumed
that when the easy handle was removed and an internal reference
was made, that version could be killed later on when a new easy
handle came using the same connection. This was wrong as Hauke's
example showed that the removed handle wasn't killed for real
until later. This caused a double close attempt => segfault.
