BTRFS: Implement a simple journaling approach, this is not finished and mostly satisfy the need for passing Transaction object for many functions.

Some details about the current Journal:
* Journal can only end transaction.
* It holds a transaction id of fs (fCurrentGeneration) that increments each time a transaction starts.
* _TransactionWritten now just printing message.

BTRFS: Implement ExtentAllocator

There are 4 new classes, structs:
* CachedExtent, is a AVLTreeNode, caches the extent locating in extent tree, a extent can be free, allocated, metadata or a data extent. It also hold a references count,
that is incremented each time a new extent refer to it (COW) and item data, that is only for allocated extent (NULL for free).
* CachedTreeExtent, is a AVLTree, cache the whole extent tree and has CachedExtent as its node.
* BlockGroup represents the group of extents that represent the region for each type of allocated extent. For example, region for data extents, metada blocks. It
responsible for inserting nodes in CachedTreeExtent.
* And the final, ExtentAllocator it knows how to allocate/deallocate extents, but for now only the allocating is implemented, actually allocating and deallocating works
are already implemented, they are in functions _AddFreeExtent, _AddAllocatedExtent in CachedTreeExtent. However the deallocating is not needed for now, so it will be
finished later then.

Revert "Fix build problems of btrfs and packagefs for x86_64."

This reverts commit f272e63f393449d3a816970ca632764895a78cd6.

Fix build problems of btrfs and packagefs for x86_64.

* Both filesystems used to link to a static kernel-zlib, which
was being built with -fno-pic. This doesn't work on x86_64 as the
filesystem add-ons are meant to be relocatable, which requires their
code to be compiled as position independent.
Solve that by moving zlib into the kernel, so any add-on can just use
it from there (packagefs is mandatory, so we can't really do without
zlib anyway).

* Referenceable.cpp: Include <OS.h> instead of <debugger.h>. The latter
