Lots of new (and hopefully useful) benchmark. Load the driver
with radeon_benchmark=<test_number> and enjoy. Among tests
added are VRAM to VRAM blits and blits with buffer size sweeps.
The latter can be from GTT to VRAM, VRAM to GTT, and VRAM to VRAM
and there are two types of sweeps: powers of two and (probably
more interesting) buffers sizes that correspond to common modes.

The value of RADEON_DEBUGFS_MAX_NUM_FILES has been used to
specify the size of an array, each element of which looks
like this:

  struct radeon_debugfs {
          struct drm_info_list    *files;
          unsigned                num_files;
  };

Consequently, the number of debugfs files may be much greater
than RADEON_DEBUGFS_MAX_NUM_FILES, something that the current
code ignores:

  if ((_radeon_debugfs_count + nfiles) > RADEON_DEBUGFS_MAX_NUM_FILES) {
          DRM_ERROR("Reached maximum number of debugfs files.\n");
          DRM_ERROR("Report so we increase RADEON_DEBUGFS_MAX_NUM_FILES.\n");
          return -EINVAL;
  }

This commit fixes this make, and accordingly renames:

  RADEON_DEBUGFS_MAX_NUM_FILES

to:

When force == false, we don't do load detection in the connector
detect functions.  Unforunately, we also return the previous
connector state so we never get disconnect events for DVI-I, DVI-A,
or VGA.  Save whether we detected the monitor via load detection
previously and use that to determine whether we return the previous
state or not.
