xfs: add log attributes for log lsn and grant head data
Create log attributes to export the current runtime state of the log to
sysfs. Note that the filesystem should be frozen for consistency across
attributes.
The following per-mount attributes are created: log_head_lsn,
log_tail_lsn, reserve_grant_head and write_grant_head. These represent
the physical log head, tail and reserve and write grant heads
respectively. Attribute values are exported in the following format:
"cycle:[block,byte]"
... where cycle represents the log cycle and [block,bytes] represents
either the basic block or byte offset of the log, depending on the
attribute. Log sequence number (LSN) values are encoded in basic blocks
and grant heads are encoded in bytes. All values are in decimal format.

xfs: add xlog sysfs kobject and attribute handlers
Embed a kobject into the xfs log data structure (xlog). This creates a
'log' subdirectory for every XFS mount instance in sysfs. The lifecycle
of the log kobject is tied to the lifecycle of the log.
Also define a set of generic attribute handlers associated with the log
kobject in preparation for the addition of attributes.

xfs: add xfs_mount sysfs kobject
Embed a base kobject into xfs_mount. This creates a kobject associated
with each XFS mount and a subdirectory in sysfs with the name of the
filesystem. The subdirectory lifecycle matches that of the mount. Also
add the new xfs_sysfs.[c,h] source files with some XFS sysfs
infrastructure to facilitate attribute creation.
Note that there are currently no attributes exported as part of the
xfs_mount kobject. It exists solely to serve as a per-mount container
for child objects.

xfs: add a sysfs kset
Create a sysfs kset to contain all sub-objects associated with the XFS
module. The kset is created and removed on module initialization and
removal respectively. The kset uses fs_obj as a parent. This leads to
the creation of a /sys/fs/xfs directory when the kset exists.

xfs: fix a couple error sequence jumps in xfs_mountfs()
xfs_mountfs() has a couple failure conditions that do not jump to the
correct labels. Specifically:
- xfs_initialize_perag_data() failure does not deallocate the log even
though it occurs after log initialization
- xfs_mount_reset_sbqflags() failure returns the error directly rather
than jump to the error sequence
