[PATCH i-g-t v2 00/33] lib/igt_kms: Implement dynamic plane count support

[Robert Foss <robert.foss@collabora.com>]

This series implements dynamic plane count support in lib/igt_kms and modifies
all of the tests that rely on a static plane count.

Currently it has has gone through incomplete testing on vc4 (many tests are intel only)
and intel (on intel-ci).

This series can be found in the branch dyn_n_planes_$VERSION on:
https://git.collabora.com/cgit/user/robertfoss/intel-gpu-tools.git/


Changes since v2:
 Rebased on upstream/master

 * igt_kms:
  - Added back kmstest_pipe_to_index() declaration
  - Fixed kmstest_plane_type_name() comment
  - Split up dyn n_planes implementation into a an additive part
    and a subtractive part to make sure that all tests work at all times
  - Fixed two igt_assert_f's that tested the wrong variable
  - Added igt_assert_f to verify that plane->index never is >= n_planes
    during igt_display_init()

Changes since v1:
 Rebased on upstream/master

 * kms_plane_multiple:
   - Fix printf cast of size_t varibles

Changes since rfc:
 Rebased on upstream/master

 * igt_debugfs:
  - Change read to read at most MAX_LINE_LEN
 * igt_kms:
  - Actually fix typo
  - Removed unused function declaration
  - Set free'd pointer to NULL after free
  - Check allocations for failures
  - Rework kmstest_crtc and kmstest_plane to support dyn n_planes
 * kms_cursor_legacy:
  - Added support for dyn n_planes
 * kms_cursor_legacy:
  - Switch to using for_each_pipe construct
 * kms_plane_lowres:
  - Added support for dyn n_planes
 * kms_plane_multiple:
  - Set free'd pointer to NULL after free
  - Check allocations for failures
