If we initialize the slab caches for the quota code when XFS is loaded there
is no need for a global and reference counted quota manager structure. Drop
all this overhead and also fix the error handling during quota initialization.

Switch the quota code over to use the generic XFS statistics infrastructure.
While the legacy /proc/fs/xfs/xqm and /proc/fs/xfs/xqmstats interfaces are
preserved for now the statistics that still have a meaning with the current
code are now also available from /proc/fs/xfs/stats.

Report all quota usage including the currently pending reservations. This
avoids the need to flush delalloc space before gathering quota information,
and matches quota enforcement, which already takes the reservations into
account.
This fixes xfstests 270.

Use the move from Linux 2.6 to Linux 3.x as an excuse to kill the
annoying subdirectories in the XFS source code. Besides the large
amount of file rename the only changes are to the Makefile, a few
files including headers with the subdirectory prefix, and the binary
sysctl compat code that includes a header under fs/xfs/ from
kernel/.
