build initramfs into kernel
...
this doesn't matter for qemu, but there's no other way of
getting a hardware device to find it if the bootloader
won't co-operate

support jffs2, with initramfs
...
the jffs2 filesystem contains only /nix/store and a script which is
run in early init (initramfs) and is responsible for recreating
"traditional" directories (/bin /etc/**/* /var &c) based on the
configuration.
this is tested only in qemu so far and could use some cleanup

We now use MIPS_CMDLINE_DTB_EXTEND for all boot varieties
(tftpboot, flash boot, kexec) with the addition of
MIPS_BOOTLOADER_CMDLINE_REQUIRE_COOKIE - local patch -
so that the bootloader args are ignored unless they
contain the string "liminix"

* at the base address we were using, the filesystem was getting
corrupted presumably because the kernel unpacked into it
* leave a little more space between compressed kernel and
squashfs. this is probably ineffective but also harmless

It's not ideal having the host key disappear when the device is
reboot, but without persistent storage the alternative is generating
it at build time. Deferring this problem to another time
