* restructured libomnitrace - this is necessary to incorporate some of the binary analysis capabilities into omnitrace exe - created libomnitrace-core (static) - created libomnitrace-binary (static) - created libomnitrace (static) - omnitrace-avail links to libomnitrace.a - omnitrace-critical-trace links to libomnitrace.a - tweaked the testing - reduced verbosity on some of MPI tests - excluded trace-time-window from tests on Ubuntu 18.04 - reduced causal e2e iterations - minor tweak to tasking - manually create `PTL::UserTaskQueue` instance instead of relying on `PTL::ThreadPool` to create it * Update formatting workflow - source formatting uses ubuntu-22.04 - check-includes doesn't generate false positive for 'include "timemory.hpp"' * omnitrace-causal --generate-configs - fix config generation in omnitrace causal - add test for omnitrace-causal + generating configs * Fix omnitrace-object-library build - accidentally included rocm sources in non-rocm builds * Fix rocm compilation w/o rocprofiler * update timemory submodule with mpi_get warning messages * sampling offload file updates - more verbose messages - disable offload before stopping * testing updates - increase causal e2e iterations to 12 - increase lock_environment verbose to 2 (for sampling offload messages) - fix return for omnitrace_add_validation_test
