For many tests, the relevant aperture is not the ppGTT but the internal
global GTT managed by the kernel. Use this limit appropriately.

No functional changes.
While I'm here, let's also rename gem_uses_aliasing_ppgtt (since it's
being used to indicate if we are using ANY kind of ppgtt) and introduce
gem_uses_full_ppgtt to drop some unnecessary code from tests that were
previously calling getparam directly instead of using ioctl wrapper.
v2: drop gem_uses_full_48b_ppgtt since it's no longer used anywhere,
s/48b/64b (Chris)
v3: rebase

2 subparts of gem_bad_reloc check that the reloc address is below the
global gtt boundary. However, when executing from ppgtt the reloc
address can be greater than that and still be a valid address.
To be sure that we're using the right upper limit, select it based on
the ppgtt mode.

Add a header that includes all the headers for the library. This allows
reorganisation of the library without affecting programs using it and
also simplifies the headers that need to be included to use the library.

Here is a cheap way for this test to give consistent results. This
doesn't change the usefulness of this test, hopefully.

One proposed solution only fixes up the SNA behaviour, so reduce the
test case to probe only that particular pathology.

The bug doesn't seem to occur on SNB, so we can skip the workaround and
hence we do not expect the kernel to prevent invalid relocated offsets.

This test feeds a batch containing self-references into the kernel and
checks that the relocation offsets remain as valid GTT addresses. This
is to exercise SNA passing in negative relocation deltas which can hang
the GPU if they wrap around.
