We accidentally enabled nested tables previously, and now it errors properly when the tables contain cycles. Before you'd get (or at least I got) a nice lua stack overflow error.

I don't necessarily like having to do these extra calls whenever threads are
spawned (and what happens to signals during the time signal delivery is
disabled?) but it seems to fully fix os.execute.
NOTE: Also disables signals when loading openal, as it or one of its backends
spawns threads internally, and does not disable signals itself.

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.
