- used for integration testing

* Update lib/common/container/small_vector.hpp

- documentation notes

* Update tests/apps

- update transpose app (fix build)
- add reproducible-runtime app

* Update include/rocprofiler/fwd.h

- rocprofiler_service_callback_phase_t -> rocprofiler_callback_phase_t

* Update PTL submodule

- fix for task group: submitting tasks from different thread

* Update lib/rocprofiler/hsa/queue.cpp

- CHECK_NOTNULL(_buffer)

* Update lib/rocprofiler/hsa/hsa.cpp

- use buffer::get_buffer instead of manually looking for buffer

* Update lib/rocprofiler/internal_threading.cpp

- use buffer::get_buffer instead of manually looking for buffer

* Update lib/rocprofiler/buffer.cpp

- offset the buffer id
- properly handle rocprofiler_create_buffer reusing rocprofiler_buffer_id_t on a different context

* Update tests

- kernel tracing library for integration testing

* Add cereal submodule

* Update lib/rocprofiler/registration.*

- Support ROCP_TOOL_LIBRARIES for python usage
- improve finalize function
- remove calling hsa_shut_down in finalize function

* Update lib/rocprofiler/buffer.*

- allocate_buffer sets the buffer id value
- expose (internally) is_valid_buffer_id
- update test

* Update tests/kernel-tracing

- installation
- better organization of JSON groups
- improved messaging

* Update lib/rocprofiler/registration.cpp

- add workaround for hsa-runtime supporting rocprofiler-register

* Update tests/kernel-tracing/kernel-tracing.cpp

- fix memory leaks

* cereal support for minimal JSON

- update cereal submodule to rocprofiler branch
- change REPO_BRANCH in rocprofiler_checkout_git_submodule for cereal
- update tests/kernel-tracing/kernel-tracing.cpp
  - use minimal json
  - slight tweak putting giving contexts name in storing name + context pointer pair in map

* Update tests/kernel-tracing/kernel-tracing.cpp

- support runtime selection of contexts via KERNEL_TRACING_CONTEXTS environment variable

* Update tests

- tests/CMakeLists.txt
  - find_package(Python3 REQUIRED)
- tests/kernel-tracing
  - pytest validation

* Update CI workflow

- install pytest
- add checks for test labels

* Update scripts/run-ci.py

- change --coverage options
  - replace 'unittests' with 'tests'
- replace test label regex '-L unittests' with '-L tests'

* Update requirements.txt

- this is now an empty file since none of the packages are required for this repo

+/**
+ * @file small_vector.hpp
+ * @brief This is inspired and largely derived from llvm/ADT/SmallVector.h. It provides a STL-like
+ * vector class which uses a small allocation on the stack when the number of elements is small.
+ *
+ * This container is ideal for vectors which are allocated frequently, will more than likely only
+ * contain a few elements, and are allocated in places where performance is a concern. When the
+ * number of elements is small, storing these elements will not require a heap allocation but it can
+ * also grow to accommodate larger allocation needs. In other words, it effectively has memory
+ * allocation like std::array<T, N> until the number of elements exceeds N. Once the number of
+ * elements exceeds N, it turns into std::vector<T>.
+ *
+ * Reference: https://github.com/llvm/llvm-project/blob/main/llvm/include/llvm/ADT/SmallVector.h
