backport of upstream bug 1124

Description of problem:

backport of upstream fix http://sourceforge.net/p/curl/bugs/1124/

When curl fails on HEAD request (e.g. keepalive packet from httpd) it immediately closes connection with

* no chunk, no close, no size. Assume close to signal end

message. This can lead to infinite loops when e.g. NTLM authentication is required (curl -v -I -L -k -s --ntlm -u ACCOUNT:PASSWORD https://URL/nonexistent.html).

Version-Release number of selected component (if applicable):

curl-7.19.7-40.el6_6.1.x86_64


How reproducible:

Always

Steps to Reproduce:

1. setup httpd server with KeepAlive On
2. curl -v --head http://server/nonexistent.html
3. observe output

Actual results:

...
Content-Type: text/html; charset=iso-8859-1
* no chunk, no close, no size. Assume close to signal end

< 
* Closing connection #0


Expected results:

...
Content-Type: text/html; charset=iso-8859-1

< 
* Connection #0 to host localhost left intact
* Closing connection #0


Additional info:

Backport patch attached.
