Our variants print stack traces on failures. This will make locating
errors much easier.

Previously, peropen objects were created with a reference count of
zero. Therefore, if diskfs_create_protid fails, passing such an
object to diskfs_release_peropen would lead to a reference count
underflow.
* libdiskfs/peropen-make.c (diskfs_peropen_make): Initialize reference
count to one.
* libdiskfs/protid-make.c (diskfs_start_protid): And consume this
reference on success. Update comment.
(diskfs_create_protid): Update comment.
* libdiskfs/diskfs.h: Update comments.
* libdiskfs/io-duplicate.c (diskfs_S_io_duplicate): Adjust reference
counting accordingly.
* libdiskfs/io-reauthenticate.c (diskfs_S_io_reauthenticate): Likewise.
* libdiskfs/io-restrict-auth.c (diskfs_S_io_restrict_auth): Likewise.
* doc/hurd.texi (Diskfs Internals): Update accordingly.

* libdiskfs/diskfs.h (struct peropen): Use refcount_t for field refcnt.
* libdiskfs/peropen-make.c (diskfs_make_peropen): Initialize refcnt.
* libdiskfs/peropen-rele.c (diskfs_release_peropen): Adjust accordingly.
* libdiskfs/protid-make.c (diskfs_start_protid): Likewise. Also, the
node must no longer be locked, adjust comment accordingly.
(diskfs_create_protid): Likewise.

Some files were not normalized. In console/motd.UTF8 the additional
newline is intentional. Empty files were excluded as well.
