When an easy handle is used to download an URI which has no
Content-Length header (or equivalent) after downloading an URI which
does, the value from the previous transfer is reused and returned by
CURLINFO_CONTENT_LENGTH_DOWNLOAD. This is because the progress flags
(used to determine whether such a header was received) are not reset
between transfers.

When libcurl has said to the server that there's a POST or PUT coming
(with a content-length and all) it has to either deliver that amount of
data or it needs to close the connection before trying a second request.

Adds test case 1129, 1130 and 1131

The bug report is about when used with 100-continue, but the change is
more generic.

"test -e" is POSIX but clearly was not supported by the SunOS sh
version, -f is supported and should be a decent equivalent

With the use of the 'ntlm_auth' tool from the Samba project

Log texts also modified and some white space edits

Upgrade ILE/RPG binding to 7.21.7.
Update OS400 documentation accordingly.

We should probably also make sure that [protocol]_proxy for all possible
protocols libcurl supports are unset.

gssapi.h is used as a header name by Heimdal-style GSSAPI so it would
conflict with a private header using that name, and while renaming the
header I figured we should name the .c file accordingly as well.

Modern gcc versions (4.6.X) get more picky by default and have started
to warn for unused parameters, but luckily gcc also allows us to mark
them as unused so that we can avoid the warnings.

Removed the parameters that were common to all our invocation.

This function wraps our calls to gss_init_sec_context so that we
have a unified way to talk to GSSAPI.

This change makes this callsite match the rest of the code.

We use "if(condition) {" with a space between the close paren and the
open brace.

First, the -J/--remote-header-name was wrongly sorted in the --help
output as pointed out in bug report #3349271.

Then, I changed the format of the texts to follow the man page better in
that it now uses "-A, --long" intead of "-A/--long". I also made all
additional arguments get written as in "-A, --long FILENAME" instead of
the previous "<filename>" style.

By default libcurl stops processing quote commands on failures.

Previously it would access a NULL pointer and die.

Only <curl/curl.h> is needed typically and curl/types.h has been removed

CURLM_CALL_MULTI_PERFORM stopped being a valid return code from
curl_multi_perform back in 7.20.0. All the libcurl tests are ajusted to
this and no longer check for this return code. Makes them simpler.
