cleanup:

- callbacks now have a uintptr_t "cbData" parameter (instead of
haphazard void*/uintptr_t, cb/ctx/data)
- resource loading code now more uniformly deals with u8* pointers
instead of void*

allocators: add support for page_aligned_alloc via boost::shared_ptr.
add evil hack to avoid the need for default ctor and ensure alignment in
SingleAllocator
archive: improve Decompressor
compression:
. near complete rewrite (previous code was a poorly factored mess)
. fix bug related to buffer allocation
. no longer provide get_output API (prone to abuse)
. add call to get max. size of output buffer (for preallocation)

This was SVN commit r5370.
