Port the xattr functionality to the new xattr_handler API.
This is smallest changes needed to move to this new API. The
function ll_removexattr can be replaced by generic_removexattr
as well since it also uses the xattr_handler set xattr backend.
To tell the difference between the two cases we test the flag
passed in for XATTR_REPLACE. The ll_getxattr function is
replaced by the generic_getxattr function.

Split the function ll_getxattr_common into two functions.
The code used for listing xattrs and ll_getxattr_common is
placed into a new function ll_getxattr_list. This allows
ll_listxattr to call directly ll_getxattr_list instead of
going through ll_getxattr_common. This change is needed
for the upcoming VFS move xattr_handler from [s|g]etxattr.

The workqueue is being used to run deferred work for the android binder.

The "binder_deferred_workqueue" queues only a single work item and hence
does not require ordering. Also, this workqueue is not being used on a
memory recliam path. Hence, the singlethreaded workqueue has been
replaced with the use of system_wq.

System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_workqueue(), system_wq allows multiple
work items to overlap executions even on the same CPU; however, a
per-cpu workqueue doesn't have any CPU locality or global ordering
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.

SW_SYNC allows to run tests on the sync_file framework via debugfs on

<debugfs>/sync/sw_sync

Opening and closing the file triggers creation and release of a sync
timeline. To create fences on this timeline the SW_SYNC_IOC_CREATE_FENCE
ioctl should be used. To increment the timeline value use SW_SYNC_IOC_INC.

Also it exports Sync information on
