Improve static singleton memory safety (#316)

* Update GitHub links

* Update samples/api_buffered_tracing/client.cpp

- check if initialized before forcing initialization

* Add lib/common/static_object.*

- template class for creating a static allocation in the binary which has all the properties of a heap allocated singleton but does not trigger leak sanitizers

* Update include/rocprofiler-sdk/internal_threading.h

- document return values

* Update lib/rocprofiler-sdk/internal_threading.cpp

- return codes from rocprofiler_create_callback_thread and rocprofiler_assign_callback_thread
- use common::static_object for thread-pool object

* Update lib/rocprofiler-sdk/agent.cpp

- use common::static_object to store array of strings and their hashes

* Update lib/rocprofiler-sdk/hsa/code_object.cpp

- use common::static_object to store array of strings and their hashes to ensure strings exist until termination

* Update lib/rocprofiler-sdk/registration.cpp

- use common::static_object to store status and client libraries
- update return values for rocprofiler_set_api_table

* Update lib/rocprofiler-sdk/hsa/hsa.cpp

- check registration::get_fini_status() in hsa_api_impl::functor<Idx>(args...)

* Update lib/rocprofiler-sdk/context/context.cpp

- using common::static_object for correlation id map

 ## Important Changes
 
-[Roctracer](https://github.com/ROCm-Developer-Tools/roctracer) and [rocprofiler (v1)](https://github.com/ROCm-Developer-Tools/rocprofiler)
+[Roctracer](https://github.com/ROCm/roctracer) and [rocprofiler (v1)](https://github.com/ROCm/rocprofiler)
 have been combined into a single rocprofiler SDK and re-designed from scratch. The new rocprofiler API has been designed with some
 new restrictions to avoid problems that plagued the former implementations. These restrictions enable more efficient implementations
 and much better thread-safety. The most important restriction is the window for tools to inform rocprofiler about which services
