Promote intel_os.c helpers to igt_os.c, so that I can re-use them for
some additional msm tests. Just big churny rename, no functional change.

We can choose which compile warnings to enable, but once they are enabled
treat all warnings as error. This enforces stricter checks against compile
warnings creeping in.
v2: Fix redefinition warning errors from i915/gem_userptr_blits
v3: Fix the even more pedantic clang compilation
v4: Do not alter whitespace in lib/tests/igt_describe!
Note: clang does not build assembler/

The width is specified in pixels, and we use 32bpp, so we were a factor
of 4 out in setting the row size to be in MiB.

If a pagefault handler fails with ENOMEM (VM_FAULT_OOM), it calls the
oomkiller without warning. On smaller machines we are trying to utilize
a dumb buffer as larger as memory, expectedly failing, but unexpectedly
being killed before we perform the tests.

For the dumb_buffer@clear_create test we need to detect the correct page
size for the buffer size calculation.
We create the least sized buffer and see the page aligned size returned
from kernel, which is minimum page size kernel will allocate.

Considering that kernel returns the real memory size(page aligned)
allocated, nonaligned buffer tests are not valid anymore. Hence removing
them.

For our threaded clear test, we want to create as many buffers as can
fit into the available memory. However, since we don't know the size of
that available memory, it can be easy to create too large or too many
buffers, and waste our time testing the unobtainable. Instead, try
probing the available space by trying to create the largest dumb buffer
we possibly can, and assume that is the equivalent to the available
space.

Dumb buffer creation and mapping are covered with test cases.
v2:
Made as a generic test for dumb buffer creation [Chris]
v3:
dumb_map is used [Chris]
Added two tests for map.
