Some of them don't apply any more (we made our choices, or the problem
has been addressed and fixed elsewhere). Some do but I reworded them.
Some still apply unchanged, and are not touched by this patch.

This is a general change that affects triggers and buffers as well.
It introduces incompatibilities but the old name was actually a bug.

The buffer was calling trig->pull_block even for output transfers.
Bug exposed by zio-trig-user.c, yet to be committed.

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

From this commit onwards the whole thing compiles and works (from
2.6.34 onwards). We chose to save you from the past history of
internal zio development.

This is the default buffer: it manages a list of data blocks
(the lenght is fixed at 16 blocks by now) for any device and
any trigger.  The actual file operations in this case are
generic, and live in zio-buf.c (zio-core.ko).
