CreateSampler should create a Sampler object by default

It should be possible to query the default parameters of a Sampler created with glGenSamplers, so checkSamplerAllocation() was added to make sure a created sampler was associated to a Sampler object where appropriate. I also cleaned up the API a little to share validation functions.
