Added an API for creating signals with attributes.
Added two APIs for IPC operations on signals.
Initial use of exceptions for error handling.
Add ref counting to signals.
Removed spin loops from signal destructors.
Signals are no longer to be destroyed with delete, use DeleteSignal instead.
Added delete safety to doorbells.
Added secondary hsa_signal_t -> Signal* translation path for IPC enabled signals.

Fall back to older apertures API and old events page size if the new APIs
fail. This allows running on current upstream kernels (with only minor
fixes) on gfx801 and enables testing of further changes during upstreaming.

Non paged system memory is allocated with node id 0. However, since a
gpu node is required for allocating system memory via KFD, the first
dgpu is used. In hsaKmtShareMemory() if system memory use the same
(first) dgpu.

Topology uses cpuid to get CPU cache information. However when running
under Valgrind, data returned from cpuid are not from the processor we set
affinity to. Instead they are all from one specific processor. For a quick
workaround so other teams can continue their work, this patch will report
CPU cache from that specific processor and ignore others.

This should allow us to take advantage of BigK fragments and huge pages
and improve TLB efficiency for VRAM allocations. Huge pages only work
with 4-level page tables (gfx900 and up). BigK fragments work on older
GPUs.

Imported graphics buffers are most likely images. Align them for
tiled image access. 64KB seems to do the trick.
This fixes VM faults with OpenCL graphics interop.

1. Correct amd::AqlQueue::ExecutePM4 to support interception.
2. Minor fixes to AqlPacket and SoftCP.
3. Minimal change to disable interception of runtime internal queues.

Performance counters have limited slots for concurrent profiling. We
need a mechanism to synchronize the slots access across different
processes. Lock file file was first used for this access control. It
reveals a RedHat bug that /var/lock, symbolic linked to /run/lock, is
not writable by others. To avoid this bug and to simplify the code,
POSIX shared memory is created to replace the lock file usage. Access
of the shared memory is controlled by semaphores.

Hardware block testing is done with the workgroup state offset
initialized to the control stack size on all ASICs. MEC microcode
assumes this space is available when the workgroup state offset is
reset after a context restore event.
Fixes context save area overrun when the full save area is used.

Libraries normally don't print messages. We use pr_err, pr_warn,
pr_info, and pr_debug to print messages to stderr when prints are
enabled for debugging.

Existing Thunk has printf/fprintf in the code while normally libraries
don't print any message. This patch introduces a print machenism similar to
how the Linux kernel prints to console based on the log level. The default
is not to print any message, but setting HSAKMT_DEBUG_LEVEL will enable the
prints.

For experimental purpose, we need an option to change compute capability
by forcing the GfxIp version. This patch allows to use environment
variable HSA_OVERRIDE_GFX_VERSION=major.minor.stepping to replace the
default version. For example:
export HSA_OVERRIDE_GFX_VERSION=9.0.1
