btrfs: use global namespace The module includes the C-style header file, thus all members are added in the global namespace. Change-Id: I5e82c8520b0495e3c437c43cfeea9cc454d39482 Reviewed-on: https://review.haiku-os.org/c/haiku/+/6653 Reviewed-by: waddlesplash <waddlesplash@gmail.com>

Fix btrfs_shell build The hacks to still use actual system headers for zlib didn't quite work. - Define Z_SOLO, which makes zlib build without any system include - Remove use of std::max and #include <algorithm> from AVLTree - Do not include DebugSupport.h because it uses system headers - Do not include uuid.h and define just what we need Now it's possible to compile the btrfs_shell on Linux.

BTRFS: Implement CopyOnWrite relevant functions, and BTree holds new attribute that record its root level. CopyOnWrite works like this: * Cache original node * Allocating new block * Cache new block to be writable * Copy original node to new node, and changing. Also if a node is already be COW-ed it cannot be COW-ed again, it will be changed in-place instead. InternalCopy does CopyOnWrite all the nodes that we don't need to change anything on them.

BTRFS: Reimplement TreeIterator, add some error checks and remove redundancies. Add BTree::Path as a attribute so enhance performance, so that everytime we iterate through items it wont search all the root to leaf again. The Iterator is initialized without rewinding to make more flexible. Signed-off-by: Augustin Cavalier <waddlesplash@gmail.com>

BTRFS: Implement BTree::Path and change _Find. Remove attribute fCurrentSlot in BTree::Node as it will be handled by Path explicitly. BTree control Path by passing its type in BTree's method, Path also hold BTree type as its attribute to do some internal actions. Add constant BTREE_KEY_TYPE_ANY, find search key has this type will success regardless of the found key's type. Split the the _Find function into Traverse and GetEntry. Traverse will fill in the Path (nodes and slots) along way its finding, GetEntry will get the item data, item size, key from leaf, if the slot is valid, that we have from Traverse. The _Find function also check type if is correct and then retrieve. Doing this way there will be more flexible, the "read" flag is not needed as we only need Path to manipulate tree, and it also enhance the performance at some points, because Path caches all the nodes from root to leaf, so that we don't have to block_cache_put and block_cache_get after each finding.
