If ROOTDIR=/rockbox and BUILDDIR=/rockbox/build-something, it is now possible to
successfully build both target binaries and simulators.

I've only implemented the not enough memory part and
expanded this idea to adding a mechanism to signal
the OOM condition of the plugin buffer which allows us to only
grab the playback buffer after garbage collection fails
(SO THE MUSIC KEEPS PLAYING AS LONG AS POSSIBLE)

This caches large files (arbitrarily defined as >1MB) in memory, which
reduces the delay when a new model or sound is needed.

The quake commit tried to optimize lcd updates but inadvertently broke
wolf3d (which always uses a 320x200 screen size). This fixes that and also
lets direct mode truly exit early to hopefully save some cycles.

add defines for sound functions
SOUND_VOLUME, SOUND_BALANCE, SOUND_CHANNELS, SOUND_STEREO_WIDTH ...
defines depend on target
require "sound_defines" to add them to rb.sound_settings[]
consolidates:
sound_set, sound_current, sound_default, sound_min, sound_max,
sound_unit, sound_pitch, sound_val2phys to a single function
rb.sound("name", setting, [value])
require "sound.lua" for old functionality

ef9ee89 introduced Read{Big,Little}{Short,Long,Float} functions to safely
read a value in memory. These incorrectly take char*, which causes them to
output erroneous 0xff bytes when given bytes with bit 7 set.

The d*_t structs are from "d"isk, which means they could be
unaligned. Packing them saves me from having to rewrite every single
access to them.

As rbcompat.h is -include'd on the command line, the mkdep script doesn't
pick it up. Explicitly add the dependency to lang_enum.h to the makefile.
Also add lang_enum.h to the 'make clean' target!

Further updated by myself
This patch breaks binary API compatibility by placing the new
functions where they make the most logical sense. IMO this is
the better approach to take given the scope of the changes needed
for talk support.
Since binary API is changing, the patch also moves some other
functions around to more logical locations.
As well as voice support in plugins, this patch voice-enables several
simple plugins. There will be follow-up patches for many plugins that
build on this one.

This ports id Software's Quake to run on the SDL plugin runtime. The
source code originated from id under the GPLv2 license. I used
https://github.com/ahefner/sdlquake as the base of my port.
Performance is, unsurprisingly, not on par with what you're probably
used to on PC. I average about 10FPS on ipod6g, but it's still
playable.
Sound works well enough, but in-game music is not supported. I've
written ARM assembly routines for the inner sound loop. Make sure you
turn the "brightness" all the way down, or colors will look funky.
To run, extract Quake's data files to /.rockbox/quake. Have fun!

This library allows events to be subscribed / recieved within a lua script
most events in rb are synchronous so flags are set and later checked by a
secondary thread to make them (semi?) asynchronous.
There are a few caveats to be aware of:
FIRST, The main lua state is halted till the lua callback(s) are finished
Yielding will not return control to your script from within a callback
Also, subsequent callbacks may be delayed by the code in your lua callback
SECOND, You must store the value returned from the event_register function
you might get away with it for a bit but gc will destroy your callback
eventually if you do not store the event
THIRD, You only get one cb per event type
["action", "button", "custom", "playback", "timer"]
(Re-registration of an event overwrites the previous one)
Usage:
possible events =["action", "button", "custom", "playback", "timer"]
local evX = rockev.register("event", cb_function, [timeout / flags])
cb_function([id] [, data]) ... end
rockev.suspend(["event"/nil][true/false]) passing nil affects all events
stops event from executing, any but the last event before
re-enabling will be lost, passing false, unregistering or re-registering
an event will clear the suspend
rockev.trigger("event", [true/false], [id])
sets an event to triggered,
NOTE!, CUSTOM_EVENT must be unset manually
id is only passed to callback by custom and playback events
rockev.unregister(evX)
Use unregister(evX) to remove an event
Unregistering is not necessary before script end, it will be
cleaned up on script exit

Rockbox constants are auto generated by a perl script like the majority
of the plugin functions.
Constants are contained in rb_defines.lua, if the file exists it is auto loaded
by the lua state for backwards compatibility
Frees ~1k

We have quite a bit of ram tied up in lua with our c libraries
I was searching for a way to free up some of this when I came
across read only tables in e-lua but that involved a lot of patching
through the source
Instead I came up with this..
it frees about 15k ram without much slowdown in code execution
since after a function gets called it is automatically added to the table
If you have a performance issue you can call the bind method
to bind a specific function or the whole table in one shot
for instance rb table
rb("lcd_clear") -- binds/returns function rb.lcd_clear()
rb(nil) -- binds every function in rb table + removes latebind metatable ..
-- added pairs and ipairs code from lua 5.2
-- cleaned up code + made more seamless
existing fields are now saved rather than overwritten when table is bound

Allows saving of ram by reusing strings already stored in the binary
and storing a pointer instead of malloc and copy to get them inside
the lua state
Saves about 1.5K overall

wl_def.h has a #pragma pack(1), which causes issues when we take the
address of an unaligned struct field. This fixes the issue by
disabling packing in fmopl_gpl.c.

This is a port of Wolf4SDL, which is derived from the original id
software source release. The port runs on top of the SDL plugin
runtime and is loaded as an overlay.
Licensing of the game code is not an issue, as discussed below
(essentially, the Debian project treats Wolf4SDL as GPLv2, with an
email from John Carmack backing it up):
http://forums.rockbox.org/index.php?topic=52872
Included is a copy of MAME's Yamaha OPL sound chip emulator
(fmopl_gpl.c). This file was not part of the original Wolf4SDL source
(which includes a non-GPL'd version), but was rather rebased from from
a later MAME source which had been relicensed to GPLv2.

The simulator build will pull in the host SDL headers, which we can't
filter out easily. A simple workaround is to simply remove the pthread
include from our SDL.
