Calculate complements by using awk's xor() function with a mask of 0xffffffff
instead of relying on the compl() function which appears to produce broken
results on certain 64bit architectures.

Hi,
the attached patch makes ipcalc.sh accept IP/Netmask combinations in
CIDR notation. Before you could only do:
# sh ipcalc.sh 192.168.0.0 255.255.255.0 1 10
IP=192.168.0.0
NETMASK=255.255.255.0
BROADCAST=192.168.0.255
NETWORK=192.168.0.0
PREFIX=24
START=192.168.0.1
END=192.168.0.11
with this patch you can also execute it with:
sh ipcalc.sh 192.168.0.0/24 1 10
IP=192.168.0.0
NETMASK=255.255.255.0
BROADCAST=192.168.0.255
NETWORK=192.168.0.0
PREFIX=24
START=192.168.0.1
END=192.168.0.11
The patch is based on #1260 [1], i just changed one line to calculate
the START end END ips right. I wonder why that never got included. If
there is no reason not to do i would like to ask you to commit that
patch, because its a functionality i (and probably others) miss quite often.
Btw, i also fixed 4 useless tabs, that might look a bit strange in the
patch.
Regards, Manuel
