Move most logic back to Source. Pool now simply contains a list of playing
sources and a mutex. Also gets rid of the pause/pauseAtomic duplication in
Source, since it can now request a lock from Pool itself.

Since the type is passed to va_start, and apparently that's undefined behaviour if it's a reference.
<Textmode> the best kind of behavior

- Type names for love's Lua objects are specified as an argument to luax_register_type, rather than being statically defined in an array.
- luax_register_type takes a variable number of method array arguments, for registering superclass methods without copying them into the subclass' method array.
Also removed most of the header declarations for wrapper functions.
All mipmap levels must be present if custom mipmaps are used (and their sizes must be half the size of the previous mipmap level, rounded down.)
Image:getData now returns all custom mipmaps in an Image.
performAtomic calls the function and passes the Channel as the first argument, plus any additional specified arguments. The called function should do as little work as possible.
To other threads, all methods for that Channel are executed in a single step inside the function. This can prevent a large number of potiential race conditions.
Example:
-- main.lua:
local function set(channel, value)
channel:clear()
channel:push(value)
return "set value"
end
assert(channel:performAtomic(set, 1) == "set value")
-- thread.lua
while true do
assert(channel:peek() == 1)
end
Previously, calling e.g. love.graphics.getFont() 10,000 times would retain the object 10,000 times (and release it 10,000 times when the Font object was garbage-collected in the Lua state.) Now it will only retain it once and release it once.
luax_pushtype keeps the object in a weak table and checks the table before creating a new userdata, so it re-uses the object's existing wrapper userdata if it can, whenever the object is pushed to Lua.
This fixes some subtle issues with love objects, where using them as keys in tables would not always work as expected (https://love2d.org/forums/viewtopic.php?f=4&t=39398&p=112388#p112415). It also decreases the amount of new Lua objects created, saving the garbage collector some work.
- Added love.system module, including clipboard functions.
- Added custom hardware cursors (love.mouse.newCursor, love.mouse.setCursor.)
- Revamped love.joystick:
-- added Joystick objects and moved love.joystick functions which operated on individual joysticks to methods on the Joystick objects.
-- Added love.joystick.getJoystick and love.joystick.getJoystickCount.
-- Added events for when joysticks are connected and disconnected.
-- Added 'Gamepad' methods to Joystick objects: Joystick:isGamepad, Joystick:getGamepadAxis, and Joystick:isGamepadDown. They're a common abstraction for xbox controller-like joystick across operating systems.
- Added monitor choosing support and "fullscreen desktop" mode to love.window.
- Moved unicode text input events to their own callback function (love.textinput), removed the key repeat functions from love.keyboard and made the second argument of love.keypressed a boolean saying whether the keypress was a repeat.
- liblove now works with love.window and love.graphics in OS X
