Some records may need to point to data with the same lifetime as the
records themselves. One solution is to store the data at the end of
the memory pool buffer. Records in the buffer grow up, and the data
grows down. When the buffer is flushed both records and data are
recycled.

Prevents cmake errors for the HIP targets such as:
HIP_ARCHITECTURES is empty for target "MatrixTranspose".

The roctracer_load, roctracer_unload, and roctrace_flush_buf functions
are not part of the ROCtracer API, and should not be exposed in the API
header file, but keep the functions in the library for backward
compatibility.
Add src/roctracer/backward_compat.cpp to implement retired functions.
Add test/app/backward_compat_test.cpp to test that the retired functions
are still accessible in the latest roctracer library.

Make error codes more informative and have negative values. This is an
ABI break but it does not appear known tools are relying on the exact
error codes.
Use logging for all errors so that roctracer_error_string will be able
to return last error message.
Make internal errors fatal and abort.
Do not use the tracer API exceptions in the tracer tool.

Add symbol versioning to the roctracer64 and roctx64 library, and only
expose the OnLoad and OnUnload tracer_tool symbols.

Add custom_commands to generate the HSA code objects
Remove the configure time file generation and add custom commands to
generate them at build time.

This should be enabled at the command line during the cmake configure
step (-DCMAKE_VERBOSE_MAKEFILE=True).
Verbose output can also be enabled during the build by setting the
VERBOSE=1 GNU make variable, or using the -v Ninja option.

Check if a default pool is defined when enabling activities.
Set default pool to undefined if it is deleted.
Disable activities associated with the pool when it is deleted.
Document restrictions on deleting pools.

Optimizing trace period to use std::threads as well as std::chrono sleep instead of sleep and usleep and catching up corner cases for ending before the trace period duration and some cosmetic clean up
Change-Id: Ia99f346bf71a3faad5dfdfc8d7a08f6c2b2cc0b9
The test (MatrixTranspose) and the tracer tool both write to stdout
which sometime causes a trace corruption.
Change the test to emit info messages to stderr instead of stdout,
leaving stdout for the tracer tool's exclusive use.

Using std::thread instead of pthreads and also atomic_bool to identify the end of the flush function so that the unload_tool can wait for it

Each thread has a thread-local record_pair_stack. The stack is
dynamically allocated on first use, but is not detroyed when the
thread exits.
Replaced record_pair_stack pointers with record_pair_stack instances,
the intances are constructed on first odr-use, and destructed when the
thread exits.
Also, converted the cb_journal and act_journal to instances.

Improve the roctx markers performance when the tracer is not engaged
(the application is not running with rocprof).
The performance of roctx push/pop, measured with:
-----------------------------------------------------------------------
auto start = std::chrono::steady_clock::now();
for (int i = 0; i < 10000000; ++i) {
roctxRangePush ("A");
roctxRangePop ();
}
auto end = std::chrono::steady_clock::now();
std::cout << "ns = " << std::chrono::nanoseconds(end - start).count()
/ 10000000 << std::endl;
-----------------------------------------------------------------------
