This is a baby-step in the direction of having finer-grained
locking than the struct_mutex. Specifically, this will enable
new debugging code to read the active list for printing out
GPU state when the GPU is wedged, (while the struct_mutex is
held, of course).

This was inspired by a patch by Chris Wilson, though none of it applied in any
way due to the debugfs work and I decided to change the formatting of the
new information anyway.

Here we eliminate a few functions in favor of using a single function
to dump from all of the object lists.

The old mechanism to formatting proc files is extremely ugly. The
seq_file API was designed specifically for cases like this and greatly
simplifies the process.

Also, most of the files in /proc really don't belong there. This patch
introduces the infrastructure for putting these into debugfs and exposes
all of the proc files in debugfs as well.

This contains the i915 hooks rewrite as well, to make bisectability better.
