just a few tweaks to the RockEv backend to allow tighter event timing
originally there was a timeout where events would be consolidated
prior to running the event thread, this slowed the faster events
but it turns out this isn't really a big waster of time
The callback from C => lua is a far bigger bottleneck

WIP for passing arguments to lua scripts
args are recognized by adding ?arg to the end of the script path
The easiest way to do this currently is to use the function rb.restart_lua
local sfile = rawget(_G, "_fullpath") or ""
local sArgs = rawget(_G, "_arguments")
if not sArgs then
rb.restart_lua(sfile .. "?my arguments")
else
rb.splash(1000, sfile .. "?" .. sArgs)
end
I'd eventually like to figure out a sensible way to do this from a
shortcut / quick list

After a few issues with the timer code in the hosted players
I realized a few shortcomings in the original rockev code...
This rewrite gives thread_exit an explicit flag instead of 0
custom events now have a set-able timeout
previous lua hooks are restored
flags are stored in uint8_t

We've already discarded the ldebug module from lua
it only makes sense to discard the debug info as well
adds 1.5 K to the binary
saves 8 Kb on the base state
once scripts start getting called i've seen 10-50Kb savings but it all depends on
what exactly you are running

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

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

In newer builds line markers prevent lua helper scripts
from grabbing some inputs especially _bool
This patch adds the -P switch
Inhibit generation of linemarkers in the output from the preprocessor.
This might be useful when running the preprocessor on something that
is not C code, and will be sent to a program which might be confused
by the linemarkers.
