5dd0c6e3c0 rewrite preinit as very small C program 
By using the kernel "nolibc" header to avoid requiring a C library, we
can bring the initramfs size to around 4k

This does involve a tiny bit of inline mips assembly which I'm not
sure about. gcc seems unwilling to generate the code to load $gp at
function entry of main(), so we do it by hand - but I'd rather find
out why gcc doesn't.

1cc0b13b57 rewrite systemconfig in C and link statically 
systemconfig (a.k.a "activate") is run from the initramfs. Converting
it from a shell script to an executable means it doesn't depend on
there being a shell in the initramfs

c744ef8c17 systemconfig: accept uid and gid options 
all we do with them is assert they're zero, to unbreak CI.
This code is getting rewritten anyway

54a1ab3529 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

25d9da967c remove support for sockets in pseudofiles 
(1) we can't make them on a real filesystem except by running
something that calls socket()
(2) whyever would we want to?

98243d43da add mtdutils mkfs.jffs2 --graft option 
we'd like a bit more of the convenience of mksquashfs
(never thought I'd say _that_) for jffs2, in particular
not having to copy all the desired store paths into a
single directory just so we can create an image from them

a172180be8 don't set lua5_3 in overlay 
sphinx depends on lua5_3, so overriding it globally means rebuilding
that - which isn't really necessary

a5cfa37ed3 unify kernel command line handling 
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"
