Revise use of types for amount of data sent or content length.

[GoogleCodeExporter]

Code isn't particularly consistent as to what type it uses where length of
content is being specified. Some times it uses 'int', some times 'long' and
other times 'apr_off_t'. For generated content, excluding wsgi.file_wrapper
then 2GB is probably maximum length of single value. There is also no
attempt to use Python specific type for string length introduced with
Python 2.5.

Thus, all code dealing with content needs to be revised and made consistent.

To get around the limitation for large files when using wsgi.file_wrapper, then 
you cannot set Content-Length 
response header as that itself is also restricted to 2GB. Simply don't set 
Content-Length and wsgi.file_wrapper 
will internally set that header with correct length of file, even if over 4GB.

I'm using HTTP HEAD command to get a filesize of a dynamic object. Response 
Content-
Length returns the object size. 

HEAD command doesn't return data actually, can we skip the check at the HEAD 
command?

miniway, why are you asking about HEAD against this issue? Bring up this issue 
on the mod_wsgi mailing list, but 
you will need to provide more details as don't know exactly what you are 
talking about. Do make sure you read:

http://blog.dscpl.com.au/2009/10/wsgi-issues-with-http-head-requests.html

Web applications should ALWAY return data for a HEAD request. Not doing so can 
cause middleware or Apache 
output filters to fail.

Closing out old issue. There could well still be issues lurking that don't know 
of, but not had specific complaints.
