[igt-dev] [PATCH i-g-t v2 0/5] Remove random allocator and improve reloc one

[Zbigniew Kempczyński]

During some debugging session with our hw team I just realized that reloc
stateless is quite big problem when I would like to collect few blits
in single batch provided by the library. Especially where are more
more objects required to acquire the offsets and not to stall if more
separate blits should be added.

I removed also RANDOM allocator, we're not using it and in softpin world
it may potentially problematic as we don't control object overlapping.

For verification real world scenario where reloc stateful is required
I changed one of subtest which previously required simple allocator
and another which requires distinguish offset (previously stateless reloc
hides this proposing new offset each alloc()).
