- Residency is being controlled by Graphics Allocation.
- Duplicates are now eliminated only for shared resources.

- add EnableLocalMemory debug variable
- separate OSInterface::osEnableLocalMemory for dll and unit tests

- extend constructor to take new flag
- extend ExecutionEnvironment createMemoryManager with new flag
- only OsAgnosticMemoryManager changes in this step

- remove Wddm parameter from WddmCommandStreamReceiver
and pass it via ExecutionEnvironment
- remove drm parameter from DrmCommandStreamReceiver
and pass it via ExecutionEnvironment
- remove void parametr from TbxCommandStreamReceiverHw

- make createGraphicsAllocationFromSharedHandle and
freeGraphicsMemory more threadsafe - there was race condition
where one thread called PRIME_FD_TO_HANDLE ioctl when the other just
closed the last handle with GEM_CLOSE ioctl. This led to situation
where newly acquired handle from PRIME_FD_TO_HANDLE was already invalid
and used in exec.
- adding mutex for the time of accessing shared handles container
and ioctls (GEM_CLOSE and PRIME_FD_TO_HANDLE) resolves racing problem

- OsInterface is now a part of execution environment
- it is created when getDevice is being called
- move ownership of wddm from Wddm Memory manager to OSInterface
- reuse osInterface on Linux in Command Stream Receiver
- currently OsInterface is not reused upon command stream receiver creation
on Windows this will change in further commits.
- make enumAdapters non static function

- createGraphicsAllocationFromSharedHandle was not threadsafe,
instead of reusing BufferObject for a single handle when
multiple threads were creating memory objects from a single VASurface,
new BO could be created and placed in container with BOs for reuse.
This was leading to errors in ioctl calls.
- add lock for following set of operations:
1. find BufferObject with a given handle in container
2. create shared BO when not found
3. add shared BO to container
prevents creating multiple BOs for a single handle
- replace recursive mutex with regular mutex as mutex shouldn't
be locked recursively

- do not always expect failures in tests with failure injections
there is retry mechanism for some cases

- new ExtendableEnum struct that serves as enum but can
be extended with values
- decrease dependencies on graphics_allocation.h header -
use forward class declaration when possible
- memoryPool indicates what kind of memory is allocated
for a given GraphicsAllocation
Change-Id: I7a707c28dc4544cc73abc5f0ed5263ba5be17452
- replace createGraphicsAllocationWithRequiredBitness with more general
methodallocateGraphicsMemoryInPreferredPool based on passed
AllocationData
- proper flags for allocation selected based on AllocationType
- remove allocateGraphicsMemory(size_t size, size_t alignment)
and use allocateGraphicsMemory(size_t size) instead where default
alignment is sufficient, otherwise use full options version:
allocateGraphicsMemory(size_t size, size_t alignment,
bool forcePin, bool uncacheable)

- change GraphicsAllocatoin::AllocationType to scoped enumeration
so that ALLOCATION_TYPE_ prefix in every enum value can be removed
- all accesses are typed (example AllocationType::IMAGE)
- Rename allocationType to AllocationUsage to eliminate confusion
with multiple AllocationType enums / types
