Rewrite bundle_deb & bundle_nupkg in Pluto

[Sainan]

This is a bit of a stretch goal, but given that by the time we need to run these scripts in the workflow, we already have compiled Pluto, the only thing stopping us is lack of functionality in Pluto itself (ignoring os.execute), which is quite frankly a bit embarrassing.

bundle_deb

Primitive reimplementation

local pluto_version
for line in io.lines("src/lua.h") do
  if line:sub(1, 29) == '#define PLUTO_VERSION "Pluto ' then
    pluto_version = line:rstrip():sub(30, -2)
    break
  end
end
assert(pluto_version, "Failed to determine Pluto version")

io.makedir("pluto")
io.makedir("pluto/DEBIAN")

local control_data = [[
Package: pluto
Version: ]] .. pluto_version .. [[
Section: custom
Priority: optional
Architecture: all
Essential: no
Maintainer: Sainan <[email protected]>
Description: A superset of Lua 5.4 — with unique features, optimizations, and improvements.
]]

local control_file = io.open("pluto/DEBIAN/control", "w")
control_file:write(control_data)
control_file:close()

os.execute("chmod 0644 pluto/DEBIAN/control")

io.makedir("pluto/usr")
io.makedir("pluto/usr/local")
io.makedir("pluto/usr/local/bin")
io.copy("src/pluto", "pluto/usr/local/bin/pluto")
io.copy("src/plutoc", "pluto/usr/local/bin/plutoc")
os.execute("chmod 0755 pluto/usr/local/bin/pluto")
os.execute("chmod 0755 pluto/usr/local/bin/plutoc")
os.execute("dpkg-deb --build pluto")

What I think could be improved:

• Native chmod function (io.chmod #471)
• Snappier way to write control file (io.contents #468)

bundle_nupkg

We definitely need some native way to fetch an HTTP resource to get the chocogen.php.
