Squashfs: add multi-threaded decompression using percpu variable
Add a multi-threaded decompression implementation which uses
Using percpu variables has advantages and disadvantages over
implementations which do not use percpu variables.
* the nature of percpu variables ensures decompression is
load-balanced across the multiple cores.
Disadvantages: it limits decompression to one thread per core.
