87c11705cc btrfs: convert the io_failure_tree to a plain rb_tree
We still have this oddity of stashing the io_failure_record in the
extent state for the io_failure_tree, which is leftover from when we
used to stuff private pointers in extent_io_trees.

However this doesn't make a lot of sense for the io failure records, we
can simply use a normal rb_tree for this.  This will allow us to further
simplify the extent_io_tree code by removing the io_failure_rec pointer
from the extent state.

Convert the io_failure_tree to an rb tree + spinlock in the inode, and
then use our rb tree simple helpers to insert and find failed records.
This greatly cleans up this code and makes it easier to separate out the
extent_io_tree code.

cde7417ce4 btrfs: use correct header for div_u64 in misc.h
asm/do_div.h is for div_u64, but it is found in math64.h. This change
will make compiler job easier and prevent compiler errors in situation
where compiler will not find math64.h from another paths.

e9a28dc52a btrfs: rename tree_entry to rb_simple_node and export it
Structure tree_entry provides a very simple rb_tree which only uses
bytenr as search index.

That tree_entry is used in 3 structures: backref_node, mapping_node and
tree_block.

Since we're going to make backref_node independnt from relocation, it's
a good time to extract the tree_entry into rb_simple_node, and export it
into misc.h.

79c8264e44 btrfs: add 64bit safe helper for power of two checks
As is_power_of_two takes unsigned long, it's not safe on 32bit
architectures, but we could pass any u64 value in seveal places. Add a
separate helper and also an alias that better expresses the purpose for
which the helper is used.

602cbe91fb btrfs: move cond_wake_up functions out of ctree
The file ctree.h serves as a header for everything and has become quite
bloated. Split some helpers that are generic and create a new file that
should be the catch-all for code that's not btrfs-specific.
