removed unsused ldap module dependency since the module didnt autounload from protected address space.

added curl.res to clean target.

it when sys/poll.h is unavailable

curl_off_t and CURLOPT_POSTFIELDSIZE_LARGE is used to pass value to libcurl

data url encoded HTTP POSTs when reading it from a file.

their long option names and all descriptions are one-liners.

--keepalive-time to curl to set the keepalive probe interval. I also took
the opportunity to rename the recently added no-keep-alive option to
no-keepalive to keep a consistent naming and to avoid getting two dashes in
these option names. Eric also provided an update to the man page for the new
option.

spanking new CURLOPT_SEEKFUNCTION simply to take advantage of the improved
performance for the upload resume cases where you want to upload the last
few bytes of a very large file. To implement this decently, I had to switch
the client code for uploading from fopen()/fread() to plain open()/read() so
that we can use lseek() to do >32bit seeks (as fseek() doesn't allow that)
on systems that offer support for that.

libcurl to seek in a given input stream. This is particularly important when
doing upload resumes when there's already a huge part of the file present
remotely. Before, and still if this callback isn't used, libcurl will read
and through away the entire file up to the point to where the resuming
begins (which of course can be a slow opereration depending on file size,
I/O bandwidth and more). This new function will also be preferred to get
used instead of the CURLOPT_IOCTLFUNCTION for seeking back in a stream when
doing multi-stage HTTP auth with POST/PUT.

code to instead introduce support for a new proxy type called
CURLPROXY_SOCKS5_HOSTNAME that is used to send the host name to the proxy
instead of IP address and there's thus no longer any need for a new
curl_easy_setopt() option.

The default SOCKS5 proxy is again back to sending the IP address to the
proxy.  The new curl command line option for enabling sending host name to a
SOCKS5 proxy is now --socks5-hostname.

fails, just issue a warning and ignore the failure.

proxy do the host name resolving and only if --socks5ip (or
CURLOPT_SOCKS5_RESOLVE_LOCAL) is used we resolve the host name locally and
pass on the IP address only to the proxy.

is an inofficial PROXY4 variant that sends the hostname to the proxy instead
of the resolved address (which is already supported by SOCKS5).  --socks4a is
the curl command line option for it and CURLOPT_PROXYTYPE can now be set to
CURLPROXY_SOCKS4A as well.

function but without a return statement. While fixing that, I also took care
about adding some better comments for the generated code.

--manual text.

a file truncation problem on Windows build targets triggered when retrying
a download with curl.

and makes wrong asumptions of build target when it isn't specified. So,
if no build target has been defined we will target WinXP when building
with MSVC 9.0 (VS2008).

added the --no-keep-alive option that can disable that on demand.

a static-lib. Renamed 'OBJ_DIR' to 'WC_Win32.obj'.
