Summary: check_http reports error when server closes connection

Initial Comment:
The check_http plugin reports an error ("Error in recv()") 
if the web server closes the socket immediately after 
sending all data. check_http goes call recv() again and 
gets ECONNRESET.

In addition, if this happens when HAVE_SSL is defined, 
then check_http will segfault because the call to 
SSL_get_error is not protected by "if (use_ssl)".

A patch for both of these against check_http.c 1.32 is 
attached.

patch applied. Many thanks (also for the java to test
against - sure makes things easy on my end)

A simple Java HTTP server app is attached - it closes the 
socket immediately after serving the data to help duplicate 
the problem. It listens on port 8911, so use "check_http -I 
xx.xx.xx.xx -p 8911  -u /"

You will probably need to run it on a separate box from where 
you run check_http due to the race condition in duplicating 
the bug.
