[igt-dev] [PATCH i-g-t v4 00/11] Remove libdrm remnants in i915 code

v2: rewrite instead of prime_udl/prime_nv_* removals.
v3: remove all references to libdrm-intel/intel_bufmgr
v4: rebase

I want finally remove all libdrm stuff, to get this I had to:

1. remove missed bufmgr field in i915_pipe_stress

2. rewrite prime_udl test - it is not used in CI due to lack of
DisplayLink hardware and I also don't have such hardware so
this is blind rewrite

3. rewrite prime_nv_* tests - similar to prime_udl (blind rewrite)

4. remove drm_import_export test, it exercises libdrm prime caps

5. rewrite intel_upload_blit_* benchmarks - I tried to mimic
behavior as much as possible but there'e some minor differences
in execution time. I think it is related to libdrm internals
(how it caches handles/mappings). I'm not sure but it shouldn't
much affect what benchmark is exercising.

6. remove all intel_batchbuffer_* code

7. get libdrm decode code and adopt to use in igt

8. use local decode code (taken from libdrm) in intel_dump|error_decode
tools

9. remove unused functions in ioctl_wrappers

10 remove libdrm definitions in tools/meson.build

11. remove libdrm/stubs definitions in lib/meson.build + libdrm stubs
