c18f07f02f aarch64: make tftpboot work
- patch dtb to add reserved-memory stanza for the phram device to use
  (aarch64 does not accept memmap= command line option)

- patch phram driver to use memremap() instead of ioremap() as
  ioremap can't be used for system ram on arm devices

be22fbbb0a bootable aarch64 liminux with qemu
I may have broken the run-liminix-vm command a bit for MIPS due to
necessary changes in how we pass the command line.  If CI isn't green
for this commit and youre trying the worked examples, I suggest
reverting to the commit before this one.

343d3b6508 writeFennel is writeFennelScript with knobs on
The second parameter is now an options attrset, wherein we will pile
all kinds of cool stuff.

Right now the only cool bit is `mainFunction`, which allows you to
compile a fennel module into a lua script and name the function that
should be executed when the script runs. This makes it easier to
write testable Fennel code, because the test script can require the
module and call stuff in it.

fbb2c04132 move module-based-service parameter types into service
This is in preparation for writing something that extracts them
into documentation.

user configurations now call config.system.service.foo.build { ...params }
instead of config.system.service.foo

the parameter type definitions themselves now move into the
config stanza of the module referencing the service

new helper function  liminix.callService

69e6eb5a89 accept attr args to pppoe service, and typecheck them
We use (abuse, arguably) the nixos module system for typechecking.  Un
the plus side, it gives us documentation of the options and their
expected types. On the downside, the error message doesn't tell us
the file in which the error was encountered.

(This is subject to change, if I can find a better way)

c3bb33c9ce add fennelrepl package
Runs fennel using a Lua compiled with the same options as the
host system, and with packages set up so it can find all the local
Lua packages

To shorten the dev feedback loop further, allows FENNEL_PATH to be set
on the command line so you can point directly it at the Fennel sources
for some library you're working against instead of having to run
nix-build and compile them to Lua

Previously: the service wrote a timestamp and the receiver

for remembering the *previous* state and only updating if it's changed

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.
