David Sterba 56e9963474 btrfs-progs: libbtrfs: hide unused symbols, same version
Another step to decommission libbtrfs in favor of libbtrfsutil. Remove
all symbols that are not used by snapper, as this is the only known
widely distributed tool that uses some of the librarized functionality,
apart from the ioctls.

The symbol versioning does not allow to remove once exported symbol so
this is a dirty trick that works only in this situation. The unused
symbols are not exported anymore BUT the library has the same version.
This would be normally an ABI violation, but there's no change for
snapper (build and runtime verified on version 0.9.0).

The known used symbols are preserved.

* btrfs_subvolid_resolve
* btrfs_read_and_process_send_stream
* subvol_uuid_search_init
* subvol_uuid_search
