[PATCH v2 0/3] Bootstrap the btrfs_find_item interface

[Kelley Nielsen <kelleynnn@gmail.com>]

There are many btrfs functions that manually search the tree for an
item. They all reimplement the same mechanism and differ in the
conditions that they use to find the item. Zach Brown proposed 
creating a new core interface, btrfs_find_item, take the place of
these functions, and standardize the search functionality.

This patchset takes the first steps toward the implementation of this
core interface. Create a starting point for the interface by moving 
one of the search functions, __inode_item, to ctree.c and renaming 
it with the core function name. With the next two patches, eliminate 
one similar helper function each by replacing their callers with 
calls to the new core function, and modifying the new core
function to ensure it fulfills the purpose of the function being
replaced.
