[PATCH v2 09/13] btrfs-progs: Fix missing-prototypes warning caused by non-static functions

[Qu Wenruo <wqu@suse.com>]

Make the following functions static to avoid missing-prototypes warning:
 - btrfs.c::handle_special_globals()
 - check/mode-lowmem.c::repair_ternary_lowmem()
 - extent-tree.c::btrfs_search_overlap_extent()
 - free-space-tree.c::convert_free_space_to_bitmaps()
 - free-space-tree.c::convert_free_space_to_extents()
 - free-space-tree.c::__remove_from_free_space_tree()
 - free-space-tree.c::__add_to_free_space_tree()
 - free-space-tree.c::btrfs_create_tree()
