For small copies cache flush latency is larger than data transfer
latency in local VRAM. Select SDMA for small copies.
Environment key HSA_FORCE_SDMA_SIZE is added for easy adjustment
of the small copy size. This may be removed after tuning is done.

- Make code object reader use mmap when loading from a file on Linux.
- Support computing code object URI for memory either fro the loaded
host executables, or from all mmapped files. Define the environment
variable HSA_LOADER_ENABLE_MMAP_URI to non 0 to search the mmap
files, otherwise only the loaded executables will be seatched.
- For mmap search, determine file size and ommit offset and size URI
fragment when the code object is the whole file even when specifying
a file size explicitly or specifying memory that has been mmaped.
- Always return a non-empty code object URI.
- When a code object reader is created, complete all fields to ensure
it can be used in a multi-threaded manner using only const
operations.
- Add missing exception handlers in the AMD vendor extentions.
- More rigorous checking for errors.

Memory from the suballocator may be exported via IPC. If this
happens then the allocating process should not reuse that memory
since it would still be connected to the remote process. IPC exported
memory must be released back to the driver.

Setting to 1 prevents the scratch handler from reducing peak occupancy.
Scratch allocations that would normally reduce peak occupancy will
instead fail.
Diagnostic for TF and PyTorch.

Joined threads can not be joined more than once nor can they be detached.
Thread library wait and close allows multiple waits and separate close so
this fixes the pthread implementation.

Fix pitch overflow due to small element detection.
Add wide pitch 2D copy handling.
Cleanup code duplication.

Adds env flag HSA_REV_COPY_DIR. If set to 1 async copy will
copy from dst device to src device rather than from src to dst.

Remove "zombie" queue state and report queue creation failure via
exceptions. Make Shared object a final container and support array
objects with Shared. Add message printing to hsa_exception in
debug builds.

GCC can't reasonably be told that the lock ptr isn't null. Adding a private bool
allows the branch to be eliminated, along with the bool.

Track pointer info for sub 2MB fragment allocations in allocation_map_.
Add fragment support to IPC.

When a fatal memory fault occurs the scheduler context-saves all queues
in the process and notifies the runtime through the memory event. The
saved state contains all GPR/LDS data at the moment of the fault.
Retrieve this state and present it to the user if HSA_DEBUG_FAULT is set
to "analyze" and the wavefront caused the fault. If amdgcn-capable objdump
is in the PATH invoke this to disassemble code around the PC.
Queue lifetime is now managed by the runtime to allow querying the
context save state for all active queues.

- Build system fixes
- No user-mode high-precision timer by default, use clock_gettime
- Use C11 aligned_alloc pending C++17 std::aligned_alloc
