[PATCH] Add retain_initrd boot option

Add retain_initrd option to control freeing of initrd memory after
extraction.  By default, free memory as previously.

The first boot will need to hold a copy of the in memory fs for the second
boot.  This image can be large (much larger than the kernel), hence we can
save time when the memory loader is slow.  Also, it reduces the memory
footprint while extracting the first boot since you don't need another copy
of the fs.
