d7ecc72b41 lang: ast, gapi, interfaces, parser: Print line numbers on error 
This adds an initial implementation of printing line numbers on type
unification errors. It also attempts to print a visual position
indicator for most scenarios.

This patch was started by Felix Frank and finished by James Shubin.

1f90de31e7 lang: core: net: Add a new func for URL parsing 
This is a first attempt to add a new function for URL parsing, using
go's net/url package and the simple API. This is still a barebones
implementation, there's possibility to expose more information. It also
includes simple tests.

b5384d1278 engine: resources: Adding logic for svc unit state 
This is a small patch that adds logic for checking what's the state of
the unit file and making the CheckApply function more robust

d80ec4aaa7 engine: resources: Detect simple self-referential frags 
It would be a likely mistake to create a self-referential frag, and mgmt
would spin forever updating the file... We probably don't want this, so
let's just catch this case in Validate.

Of course you could get around this with multiple files, and a fancier
search could statically check the graph, but the goal isn't to prevent
any bad code, since that's not likely to be possible.

a064a87ecd lang: Add a weird test case 
Mark Smith was concerned we might not handle this case correctly. It

1e33c1fdae misc: Add vim syntax highlighting file 
This is an extremely basic initial version of syntax highlighting, written just
so that I can edit the MCL files in vim and not cry.

The following features are supported:
 - MCL keywords
 - strings (including escape characters)
 - comments
 - built-in resources (as of 0.0.27)

These are really stubs, and need some more testing and integration, but
there were some people who expressed interest in this, so let's push it

Instead of constantly making these updates, let's just remove the year
since things are stored in git anyways, and this is not an actual modern

483cc22c32 lang: core: embedded: provisioner: Add IPXE support 
This lets you boot from ipxe. You can run the ipxe shell from their
stock image or the netboot.xyz one. For the latter, press "m", then type
"dhcp" (machine is now pingable!) then type "route" to check the ip.

To boot type:

chain http://192.168.42.1:4280/menu.ipxe

and you're off!

Thanks to frebib for finding the workaround to the VFS bug. The answer
is you need to run the imgfree command to unblock the initrd.

cace2bacb8 lang: core: embedded: provisioner: Add support for module path 
This is needed for bigger code bases. Remember: this is consulted at the
deploy stage, and the deploy contains the entire tree (including
modules) of everything it needs to run. This is why you don't need to
add a --module-path arg when running mgmt in systemd with the "empty"
frontend.
