btrfs: move btrfs_map_token to accessors
This is specific to the item-accessor code, move it out of ctree.h into
accessor.h/.c and then update the users to include the new header file.
This un-inlines btrfs_init_map_token, however this is only called once
per function so it's not critical to be inlined. This also saves 904
bytes of code on a release build.
