Description:
------------
in php_apache_request_ctor (sapi/apache2handler/sapi_apache2.c)

	SG(request_info).content_length = (content_length ? atoi(content_length) : 
0);


so when the content_length exceed INT_MAX,  the content_length will be a wrong 
value. 

Test script:
---------------
none

Expected result:
----------------
none

Actual result:
--------------
none

actullay this cause the upload progress(also apc, session upload progress) return 
wrong message when try to uploading   bigger than 4GB file in 64-bit OS.

change atoi to atol can make this more sense(long content_length in the 
request_info struct defination)
