POST not working for daemon mode when client expects 100-continue.

[GoogleCodeExporter]

If using curl to submit POST data, or Opera web browser and request content was 
over 10kb, the 
client will ask that a 100-continue status response be generated by server 
before actually 
sending any data.

Problem is that if WSGI application is run in daemon mode, this situation was 
causing request 
content to be truncated and the WSGI application would see no input.

Further details in:

  http://groups.google.com/group/modwsgi/browse_frm/thread/5aa9a30a36502246

The incorrect behaviour in this case is caused by mod_wsgi code fiddling with 
temporary request 
status, setting it to 0. This was causing a test in Apache HTTP input filter to 
fail and instead of 
returning the 100-continue response header, it was pushing an EOS bucket into 
input stream.

Fix is to reset request status to HTTP_OK after handshake sequence with daemon 
process that 
determines if daemon process will be restarted.
