btrfs-progs: inline btrfs_name_hash and btrfs_extref_hash

Browse Source 
This is the opposite of what we do in the kernel, however in the kernel
we put the helpers in dir-item.h and inode-item.h respectively.  Those
do not exist in btrfs-progs right now, so instead of doing all that work
right now simply inline them in ctree.h to make it easier to sync
ctree.c from the kernel.
