Paul Molloy pinkASUS 4a24f72e3f Now able to make dictionary call from lua scripts.
Currently have redefined table that needs to align with shared dictionary
files.

Next task is to parse shared dictionary files to create tables at runtime.

Paul Molloy pinkASUS 2fdefde840 Have basic lua scripting working.
scripts/usb_device.lua is planned to use for usb device info prior to
connecting.  Currently just used to determine log level.

scripts/inlretro.lua is the main script called by the C main function.
Prior to passing control over to lua in inlretro.lua, commandline args
must be passed in somehow.  And the USB device must be connected to, and
usb transfer object passed to dictionary's local transfer pointer.

Not sure dictionary having a local static pointer to usb transfer struct
is a great idea, but simplest solution I could think of to keep from
complicating lua by passing the pointer/object back and forth between lua
and C.  This method mostly abstracts the usb transfer object from lua
which makes sense to me anyway.

Need to come up with a way for shared_dict_*.h defines to be made
available to lua scripts.  Seems a lua table would be the best solution,
but don't want to keep manual copies for all the defines.  These C defines
are necessary as it's the only clean way to define the dictionaries for
the firmware.  Thinking the best solution will be a lua script that
parses all shared_dict*.h files and creates tables at run time.  Planning
to hardcode some tables for now, then implement a .h file parser in lua.

Paul Molloy 2cc77e5fba Basic Lua operations working. Code from "programming in Lua 4th ed" by
Roberto Ierusalimschy.

Currently using Lua 5.3.4 downloaded from: https://www.lua.org/ftp/
lua.c and luac.c are the only files excluded as those are the standalone
lua(c) source files which aren't intented for this embedded solution.
License and logo included in lua/doc dir as required/requested.

Currently just have basic Lua creating lua state, loading libraries.
Then loading test.lua file which contain variables.
Which are then retrieved and printed.

Planning to put nearly all control code in lua which addresses all my
frustrations and complaints from last commit.  The more I learn about lua
the more I like it and look forward to it's use.  Planning to implement
the entire gui with lua as well, potentially wxlua
http://wxlua.sourceforge.net/

Plan is to do some basic lua pulling of USB device from lua scripts.
Then modify/create usb functions which can be called from lua directly.
With that should be able to start building up lua scripts to perform
everything which is currently handled by lua code.
