Added direct I/O support. The current implementation uses O_DIRECT,
which is not posix standard and is tested on linux 2.6.21.
Currently only file allocation uses direct I/O.

Implemented BitTorrent/http/ftp integrated download.
I've rewritten lots of files and now some headers have forward
class declarations to reduce compile time.
The implementation is extremely alpha stage, I recommend to use this
for testing purpose only.
