Remove final traces of long-deprecated "ramdisk" kernel parm

Since the "ramdisk" kernel parameter has been officially deprecated
since at least 2.6.18, might as well finally get rid of it.

The old "ramdisk=<ram_size>" has been changed to "ramdisk_size=<ram_size>" to
make it clearer. The original "ramdisk=<ram_size>" has been kept around for
compatibility reasons, but it may be removed in the future.
There are also config symbols (in the Block drivers config menu) for these
variables: BLK_DEV_RAM_SIZE defaults to 4096 and BLK_DEV_RAM_BLOCKSIZE
defaults to 1024.
The new RAM disk also has the ability to load compressed RAM disk images,
allowing one to squeeze more programs onto an average installation or
rescue floppy disk.
