[Piglit] [PATCH 0/4] ARB_separate_shader_objects V3

[gregory]

TEST status:
IsProgramPipeline:
    * neither AMD/NVIDIA follow the spec...
    * Crash on AMD: because of -1 of glGenProgramPipelines( -1, id)
    * Crash on Nvidia: glGetProgramPipelineiv(4, GL_VERTEX_SHADER, &value).

GetProgramPipelineiv:
    * working on nvidia
    * FGLRX only accept as Active Program, program that was previously attached to
    the pipeline. No mention in the spec

mix_pipeline_useprogram:
    * working on nvidia
    * FGLRX doesn't restore the pipeline when single program is unattached (glUseProgram(0))

ValidateProgramPipeline:
    * PART 6 is bad on nvidia only (good on FGLRX)
    * PART 11 is bad on FGLRX only (good on nvidia)
    * PART 12 are bad on both drivers. Technically the spec said that the pipeline must be bound
    and current to check the GL_PROGRAM_SEPARABLE flags. But it doesn't make any sense on a bindless
    free api... I try to bind it on FGLRX but I didn't see any change. Don't know on nvidia side. 

api-errors:
    * working on nvidia
    * FGLRX doesn't report any error


*****************************************************************

V3:
* Fix all test on Nvidia GPU.
* Add a new test ValidateProgramPipeline

V2:
* split the patch properly with git :)
* sso-GetProgramPipelineiv: fix a VS linker error. Print current test
  step.
* sso-mix_pipeline_useprogram: fix a wrong expected. Now the test must
  work on nvidia :)
* sso-IsProgramPipeline: Print more current test step
	=> my guess is  nvidia choke on glDeleteProgramPipelines( -1,  
	   id);
	=> Nvidia as AMD doesn't follow the spec (not very serious)

  piglit util: new functions piglit_program_pipeline_check_status/quiet
  add 3 news tests for arb_separate_shader_objects
  update EXT_transform_feedback error detection
  SSO: new test ValidateProgramPipeline
