This patch does the following:
  - it adds a new header for sysfs
  - it changes zio-sys.c to support per-instance trig/buf attributes
  - it renames some functions
  - is simplifies sysfs handling

This changes some method and stuff, in order to make all input and
output be cset-based. This solves a number of issues with the previous
setup. Thus, even drivers must be made differentlym abd this fixes
zio-zero accordingly.

As a side effect, we have a data_done method in trigger ops, so the device
can tell when it is done. And the fire_trigger returns void, since it
cannot wait for stuff to be done. See documentation for details.

zio invokes try_module_get() on buffer, trigger and device owners when
they are in use. For devices we still have a little unsafe time.

A trigger instance has flags too, and the create functions
set the flag in bot bi and ti. And channels inherit from cset.

zio_sys_operations are in several structures, so remove the
info_get and conf_set methods from device operations.

These two headers devine the structures and operations for buffers
and trigger. Additionally, zio-buffer.h defines the control structure
and the data block.

This includes all the sysfs definitions and structures, together with
the main data structures for devices, csets and channels.
