Due to ambiguity of error values in the public API subvol_uuid_search,
there was second version added. There's a separate copy in libbtrfs and
we don't have to distinguish in the internal code. All callers check for
IS_ERR and NULL, so we can safely merge the helpers into one.

After removing uuid search fallback code the structure has become
trivial and copies the fd that all callers have in their context.

After the uuid search fallback code has been removed, the finit helper
has become empty and can be removed.

There's a lot of code under BTRFS_COMPAT_SEND_NO_UUID_TREE to support
kernels < 3.12 that don't have uuid tree and the subvolume uuids are
searched in a slow way, building the uuid tree on the userspace side.
As the uuid tree is always created, the fallback code was not exercised
anyway due to 'uuid_tree_existed' check in subvol_uuid_search2.
Delete the code from the internal copy of send-utils. The support still
stays for libbtrfs and will be removed in the future.

The btrfs_list_* functions come with some overhead and for simple path
resolution we can use btrfs_subvolid_resolve.

We don't need to include this besides btrfs-list.c itself and
subvolume.c that does use the btrfs_list_* API.

The function btrfs_list_get_path_rootid is exported to libbtrfs so it
needs to stay, but we can inline the implementation.

The path-util.[ch] is the right place, keep the send-utils.h prototypes
as it's part of libbtrfs headers.
