Replace the stop reasons ttmp11.trap_raised and ttmp11.excp_raised
with ttmp11.wave_stopped which indicates that the trap handler has
halted the wave as the result of an event (trap, single-step or
exception).
If the wave is stopped because of a trap, also record the trap_id in
ttmp11.saved_trap_id[7:0].
Save status.halt in ttmp11.saved_status_halt, so that it can be
restored when resuming a wave (changing a wave's state from stopped to
running or single-stepping).

To support single stepping the instruction preceding an s_endpgm,
unwind the PC by 8 bytes and set ttmp11[9] to notify the debugger
that the wave is halted with a modified PC.
Bump the debug r_version for this new trap handler ABI.

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.

The excess declarations mark implemenation functions as default
visibility. Normally this is not an issue since our linker script
will specify which visible symbols will be permitted into the dynamic
symbol table. However, for static linking methods which apply linker
directives during incremental linking symbol visibility must be correct
in the (non-dynamic) symbol table.

The size of the m0 payload for MSG_INTERRUPT has changed in gfx10. It is
now 23bit wide instead of 24bit wide in gfx9.
Since we are generating different binaries for gfx9 and gfx10, we can
conditionally set DEBUG_INTERRUPT_CONTEXT_ID_BIT to 23 for gfx9 and
22 for gfx10.

- 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.

Save and restore exec_lo/exec_hi around the mGetDoorbellId macro in
the signal_error case just like we do in the signal_debugger case.
Also reset the wave_id (ttmp4/ttmp5) to 0 since it isn't preserved.
0 will be detected as a new wave by the debugger api library.

- A pair of queries on a loaded code object to get the URI name/length.

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.

The 1st level trap handler jumps to the 2nd level trap handler on
context save requests or regular traps if (mode.debug_en
&& !status.halt) is true.
If we return from the 2nd level trap handler without status.halt=1, then
we need to make sure mode.debug_en is cleared, or we will re-enter the
2nd level trap handler again and again when trapsts.savectx is set.

In the case where SQ_WAVE_TRAPSTS_XNACK_ERROR_MASK is set, we also need
to set the TTMP11_EXCP_RAISED_BIT in ttmp11. If we don't, the debugger
may think that the wave is halted at launch (halted without events).

New trap handler ABI: Record in ttmp11[8:7] the event that caused the
trap handler to be entered. We currently record 2 events, trap_raised
if an s_trap instruction was executed, or excp_raised if an exception
(MEM_VIOL or ILLEGAL_INST) was raised.

scratch_used_large_ was uninitialized leading to the observed hang.
DynamicScratchHandler would wait for a large scratch release despite no
large scratch having yet been allocated. Fixes .
The patch also removes a potential race between AddScratchNotifier and
ReleaseQueueScratch. The race condition does not exist today since both
scratch alloc and release run on the same thread. The changes will
prevent this potential race from manifesting if the async event handler
is ever updated to use multiple threads.
Also enhances scratch occupancy reduction reporting. Reporting now
prints the initial request size as well as the allocated size and the
effect on occupancy this has. Occupancy is computed in terms of the
requesting dispatch grid size so may be >100%.

sdma end ts must be 256 bit aligned in oss 3.0 and prior. Using
the ts pool requires copying into the signal and is a significant
performance penalty for small copies.
SharedSignal is 128 bytes due to alignment so can host the end ts.
Move sdma end ts into SharedSignal and remove ts pool and ts copy.
