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

allows rocklib_img to be excluded if needed
stops rocklib_aux from generating redundant prototypes for
lcd_mono_bitmap[_part]

I previously noticed that manually clearing the framebuffer while scroll
function was active caused lua to crash
I could reproduce in sim and on device but I thought using the plugin
supplied rb->lcd_clear_screen was immune to this issue
Unfortunately some devices exhibit this behavior with the plugin function
as well
This patch adds rb->lcd_scroll_stop() before lcd_clear_screen at lua start-up
and to the supplied include file lcd.lua

FILE typedef to *void needs more work to not break sim and
application builds. I checked only a few random native builds
unfortunately. Sorry for inconvenience.

Prior to this patch the Lua plugin used version 5.1.4. This change
reduces the number of modifications in the Lua source using some new
defines and because the upstream source is now more flexible.
Unless otherwise stated, l*.[ch] files are taken unmodified from the
upstream lua-5.2.3.
fscanf.c:
file descriptors in rockbox are just ints, they are hidden behind a
void* now so liolib requires less modifications. fscanf is updated to
use void* too.
getc.c: this is a new file required for getc implementation in lauxlib.c
lauxlib.c: LoadF replaced FILE* with int, the rockbox file
descriptor int are cast to FILE* (actually void* due to typedef).
getc uses the PREFIX version. stdin is not used, as per 5.1.4.
lbaselib.c: now uses strspn in the number parsing. print uses DEBUGF now
rather than being commented out.
lbitlib.c: use the built-in version from 5.2.3 rather than Reuben
Thomas's external library. Backwards compatible and adds some new bit
operations.
ldo.c: the LUAI_THROW/TRY defines are now in the core lua code, so have
been removed from rockconf.h
liolib.c: here the implementation has changed to use the LStream from
the original source, and cast the FILE* pointers to int. This has
reduced the number of modifications from the upstream version.
llex.c: the only change from upstream is to remove the locale include.
lmathlib.c: updated from the 5.2.3 version and re-applied the changes
that were made vs 5.1.4 for random numbers and to remove unsupported
float functions.
loadlib.c: upstream version, with the 5.1.4 changes for missing
functions.
lobject.c: upstream version, with ctype.h added and sprintf changed to
snprintf.
loslib.c: upstream version with locale.h removed and 5.1.4 changes for
unsupportable functions.
lstrlib.c: sprintf changed to snprintf.
ltable.c: upstream with the hashnum function from 5.1.4 to avoid frexp
in luai_hashnum.
luaconf.h: updated to 5.2.3 version, restored relevant parts from the
original 5.1.4 configuration. The COMPAT defines that are no longer
available are not included.
lundump.c: VERSION macro conflicts with the core Rockbox equivalent.
rocklib.c: luaL_reg is no longer available, replaced by luaL_Reg
equivalent. Moved checkboolean/optboolean functions to this file and out
of core lua files. luaL_getn is no longer available, replaced by
luaL_rawlen. luaL_register is deprecated, use the newlib/setfuncs
replacements. rli_init has to be called before setting up the newlib to
avoid overwriting the rb table.
rocklib_aux.pl: use rli_checkboolean from rocklib.c.
rocklua.c: new default bits library used, update the library loading
code with idiomatic 5.2 code.
strcspn.c: no longer needed, but strspn.c is required for strspn in
lbaselib.c

Instead of providing yet another memory allocator implementation
use tlsf and simply link tlsf library.
Another small improvement is to *grow* memory pool by grabbing
audiobuffer instead of just switching to use audiobuf exclusively.
Tested with simple lua 'memory eater' script.
This patch extends tlsf lib slightly. You can provide
void *get_new_area(size_t * size) function which will override
weak dummy implementation provided in lib itself. This allows to
automaticaly initialize memory pool as well as grow memory
pool if needed (for example grab audiobuffer when pluginbuffer
is exhaused).

It handles exit() properly, calling the handler also when the plugin returns
normally (also make exit() more standard compliant while at it).
It also holds PLUGIN_HEADER, so that it doesn't need to be in each plugin anymore.
To work better together with callbacks passed to rb->default_event_handler_ex() introduce exit_on_usb() which will call the exit handler before showing the usb screen and exit() after it.
In most cases rb->default_event_handler_ex() was passed a callback which was manually called at all other return points. This can now be done via atexit().
In future plugin_crt0.c could also handle clearing bss, initializing iram and more.
