using int is not fine on 64bit systems

strlen() returns size_t, but ssh libraries are wanting 'unsigned int'.  Add
explicit casts and use _ex versions of the ssh library calls.

Use ssize_t instead of int for the Curl_smtp_escape_eob nread
argument.

If you pass a URL to pop3 that does not contain a message ID as
part of the URL, it will currently ask for 'INBOX' which just
causes the pop3 server to return an error.

The change makes libcurl treat en empty message ID as a request
for LIST (list of pop3 message IDs).  User's code could then
parse this and download individual messages as desired.

My first instinct was to run the test script within the checked out
repository.  This small change to the script allows that to work as
expected.

Ben Greear brought a patch that from now on allows all protocols
to specify name and user within the URL, in the same manner HTTP
and FTP have been allowed to in the past - although far from all
of the libcurl supported protocols actually have that feature in
their URL definition spec.

all used while running tests

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
