Introduce a new allocation cursor data structure to encapsulate the various states and structures used to perform an extent allocation. This structure will eventually be used to track overall allocation state across different search algorithms on both free space btrees. To start, include the three btree cursors (one for the cntbt and two for the bnobt left/right search) used by the near mode allocation algorithm and refactor the cursor setup and teardown code into helpers. This slightly changes cursor memory allocation patterns, but otherwise makes no functional changes to the allocation algorithm.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
