Split ceph_show_options() into two pieces and move the piece
responsible for printing client (libceph) options into net/ceph. This
way people adding a libceph option wouldn't have to remember to update
code in fs/ceph.

pagelist.h needs to include linux/types.h and asm/byteorder.h and not
rely on other headers pulling yet another set of headers.

Request reply and cap message can contain inline data. add inline data
to the page cache if there is Fc cap.

allow specifying position of extent operation in multi-operations
osd request. This is required for cephfs to convert inline data to
normal data (compare xattr, then write object).

Use kvfree() from linux/mm.h instead, which is identical. Also fix the
ceph_buffer comment: we will allocate with kmalloc() up to 32k - the
value of PAGE_ALLOC_COSTLY_ORDER, but that really is just an
implementation detail so don't mention it at all.

When a lock operation is interrupted, current code sends a unlock request to
MDS to undo the lock operation. This method does not work as expected because
the unlock request can drop locks that have already been acquired.
The fix is use the newly introduced CEPH_LOCK_FCNTL_INTR/CEPH_LOCK_FLOCK_INTR
requests to interrupt blocked file lock request. These requests do not drop
locks that have alread been acquired, they only interrupt blocked file lock
request.

Introduce ceph_osdc_cancel_request() intended for canceling requests
from the higher layers (rbd and cephfs). Because higher layers are in
charge and are supposed to know what and when they are canceling, the
request is not completed, only unref'ed and removed from the libceph
data structures.
__cancel_request() is no longer called before __unregister_request(),
because __unregister_request() unconditionally revokes r_request and
there is no point in trying to do it twice.
