Add typechecking to the min/max macros and make their locals truly
unique-ish to reduce the risk of shadowing.
v2: small bug fix, write also height coordinate on rotation
test. (jheikkil)
v3: Fix up a couple of other max/max_t instances (Ashutosh)

When allocator is running in multiprocess mode, all queries
are processed in a designated thread in the parent process.
However, a child process may request opening the allocator
for a gpu using a file descriptor absent in the parent process.
Hence, querying available gtt size must be done in the child
instead of the parent process.
As a consequence of this change creating allocators managing
only a given interval of available gtt is now enabled for all
allocator implementations. Additionally, this commit sets a
universal lower bound on alignment to 4096.

To use spinners with no-reloc we need to alloc offsets for them
from already opened allocator. As we don't know what strategy
is chosen for open (likely HIGH_TO_LOW for SIMPLE allocator) we
want to overwrite it for spinners (there's expectation they
will reside on low addresses).
Extend allocator API adding intel_allocator_alloc_with_strategy()
to support spinners rewriting.
v2: add change in api_intel_allocator test to compile properly
whole series.

As relocations won't be accessible on discrete we need to support
IGT with an allocator. So tests which have to cover all generations
have to diverge the code and use conditional constructs.
On the long term this can be cumbersome and confusing. So we can
try to avoid such and use pseudo-reloc allocator which main task
is to return incremented offsets. This way we can skip mentioned
conditionals and just acquire offsets from an allocator.
