libtrivfs: lock-less reference counting for trivfs_peropen objects
* libtrivfs/trivfs.h (struct trivfs_peropen): Use refcount_t for field
refcnt.
(struct trivfs_control): Remove unused field lock.
* libtrivfs/cntl-create.c (trivfs_create_control): Drop the mutex
initialization.
* libtrivfs/io-reauthenticate.c (trivfs_S_io_reauthenticate): Adjust
accordingly.
* libtrivfs/io-restrict-auth.c (trivfs_S_io_restrict_auth): Likewise.
* libtrivfs/open.c (trivfs_open): Initialize refcnt.
* libtrivfs/protid-clean.c (trivfs_clean_protid): Likewise.
* libtrivfs/protid-dup.c (trivfs_protid_dup): Likewise.
