zram: add package to use compressed ram disk for swap
The busybox size is increased by 3.2KByte uncompressed on bcm47xx with this commit. This zram-swap automatically creates a zram device, a swap partition on it and make the kernel swap pages to it. Thank you Bastian Bittorf <bittorf@bluebottle.com> for idea and the script. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@35025 3c298f89-4303-0410-b956-a3cf2f4a3e73
