i965: initial attempt at fixing the aperture overflow

Makes state emission into a 2 phase, prepare sets things up and accounts
the size of all referenced buffer objects. The emit stage then actually
does the batchbuffer touching for emitting the objects.

There is an assert in dri_emit_reloc if a reloc occurs for a buffer
that hasn't been accounted yet.
