Bug description:  ip2long() calculates networks (partial ip addr.) wrong

Description:
------------
When given network addresses (partial ip addresses)*),

ip2long() calculates erratic values:



Input        Output           dechex    should be

192          int(192)         c0        c0000000

192.168      int(-1073741656) c00000a8  c0a80000

192.168.1    int(-1062731775) c0a80001  c0a80100



*) you will need this to convert 192/8, 192.168/16 etc

   network addresses.

Reproduce code:
---------------
$net=ip2long("192");

echo dechex($net)."\n";



$net=ip2long("192.168");

echo dechex($net)."\n";



$net=ip2long("192.168.1");

echo dechex($net)."\n";



Expected result:
----------------
c0000000

c0a80000

c0a80100



Actual result:
--------------
c0

c00000a8

c0a80001
