This existed when we overloaded the tree manipulation functions for both
the extent_io_tree and the extent buffer tree. However the extent
buffers are now stored in a radix tree, so we no longer need this
abstraction. Remove struct tree_entry and use extent_state directly
instead.

Now that we've moved everything we can unexport all the temporary
exports, move the random helpers, and mark everything as static again.

We no longer need to export this as all users are in extent-io-tree.c,
remove it from the header and put it into extent-io-tree.c.

This is still huge, but unfortunately I cannot make it smaller without
renaming tree_search() and changing all the callers to use the new name,
then moving those chunks and then changing the name back. This feels
like too much churn for code movement, so I've limited this to only
things that called tree_search(). With this patch all of the
extent_io_tree code is now in extent-io-tree.c.

These are the last few helpers that do not rely on tree_search() and
who's other helpers are exported and in extent-io-tree.c already. Move
these across now in order to make the core move smaller.

In order to avoid moving all of the related code at once temporarily
export all of the extent state related helpers. Then move these helpers
into extent-io-tree.c. We will clean up the exports and make them
static in followup patches.

A lot of the various internals of extent_io_tree call these two
functions for insert or searching the rb tree for entries, so
temporarily export them and then move them to extent-io-tree.c. We
can't move tree_search() without renaming it, and I don't want to
introduce a bunch of churn just to do that, so move these functions
first and then we can move a few big functions and then the remaining
users of tree_search().

This helper is used by a lot of the core extent_io_tree helpers, so
temporarily export it and move it into extent-io-tree.c in order to make
it straightforward to migrate the helpers in batches.

These are just variants and wrappers around the actual work horses of
the extent state. Extract these out of extent_io.c.

Start cleaning up extent_io.c by moving the extent state code out of it.
This patch starts with the extent state allocation code and the
extent_io_tree init code.
