Handle fork in target application (#191)
* Always print PID in log messages
* omnitrace-dl updates
- omnitrace_preload does not call omnitrace_init or omnitrace_init_tooling
- omnitrace_preload will call omnitrace_set_mpi if OMNITRACE_USE_MPI
or OMNITRACE_USE_MPIP in the env is true but not call it otherwise
because doing so either overrides OMNITRACE_USE_PID (when true) or
disable mpip from initialization (when false) and the MPI
init can be caught later and override OMNITRACE_USE_PID
* config updates
- set_setting_value sets user update type
- remove volatile from get_settings_configured
- don't override settings::default_process_suffix
- don't kill process in omnitrace_exit_action
- set_state ignores updating state if >= State::Finalized
* Handle state > State::Finalized
* fork gotcha updates
- unsets LD_PRELOAD
- sets OMNITRACE_ROOT_PROCESS
- sets OMNITRACE_CHILD_PROCESS
* libomnitrace library.cpp updates
- basic_bundle for fini metrics
- handle finalization from child process
* sampling updates
- sampling::shutdown handles when child process
* Add example and test using fork
* Update run-ci script to support not submitting
* Tweak test envs
* Update build flags when codecov enabled
* remove unnecessary includes of sampling header
* Replace mpi copy/fini static lambda with free-funcs
* Update codecov job

Binary instrumentation: more robust exclusion of functions used internally (#238)
## Overview
This PR attempts to increase the stability of binary rewrite and runtime instrumentation.
### Improved protection against self-instrumentation
Using ~~the binary analysis capabilities added from #229~~ the Dyninst SymtabAPI, OmniTrace now does a much better job of avoiding instrumentation of functions which are internally called by OmniTrace:
- The `omnitrace` executable searches for and parses the symbols of various libraries which are known to cause problems when instrumented
- GNU libraries which are common to nearly every library, e.g., `"libc.so.6"`, `"libdl.so.2"`, etc., and thus are outside the scope of the users optimizations efforts
- Libraries which OmniTrace depends on for functionality, e.g. `"libunwind.so"`, `"libgotcha.so"`, `"libroctracer64.so"`, etc.
- OmniTrace skips instrumenting any `module_function` instance when it's member `module_name` or `function_name` variable matches the library name, source file, or function name found for that symbol (unless the user explicitly requests that it be eligible for instrumentation)
- Note: the parsing of the "internal" libraries may result in longer instrumentation time and higher memory usage. Please file an issue if either of these is found to be excessive.
### Function filters based on linkage and visibility
Added options to restrict instrumentation to certain linkage types (e.g. avoid instrumenting weak symbols) and visibility types (e.g. avoid instrumenting hidden symbols).
### Function filters based on instructions
In the past, after instrumentation, some applications instrumented by Dyninst would fail with a trap signal (e.g. #147). In several cases, it was found that this occurred whenever certain instructions were present in the function so an option was added to exclude functions based on one or more regex patterns was added.
## Details
- generates list of "internal" libraries and attempts to find the first match via:
- the library is already open, e.g. `dlopen(<libname>, RTLD_LAZY | RTLD_NOLOAD)`
- searching for the library in `LD_LIBRARY_PATH`
- searching for the library in `OMNITRACE_ROCM_PATH`, `ROCM_PATH`
- searching the folders from `/sbin/ldconfig -p`
- searching for the library in common places such as `/usr/local/lib`
- provides new `--linkage` command line option to restrict instrumentation to functions with particular type(s) of linkage
- Linkage types: `unknown`, `global`, `local`, `weak`, `unique`
- provides new `--visibility` command line option to restrict instrumentation to functions with particular type(s) of visibility
- Visibility types: `unknown`, `default`, `hidden`, `protected`, `internal`
- provides new `--internal-module-include` and `--internal-function-include` command line regex options to bypass automatic exclusion from instrumentation
- provides new `--internal-library-append` command line option to specify a library should be considered internal
- provides new `--internal-library-remove` command line option to specify a library should not be considered internal
- provides new `--instruction-exclude` command line regex option to exclude functions which contain matching instructions
- provides new `--internal-library-deps` command line option to treat libraries linked to internal libraries as internal libraries
- generally, this will only be helpful during runtime instrumentation when OmniTrace is built with an external dyninst library which is dynamically linked to boost libraries and the application is using the same boost libraries
- relaxed restrictions in `module_function::is_module_constrained()`
- relaxed restrictions in `module_function::is_routine_constrained()`
- added a few miscellaneous nullptr checks
## Miscellaneous
- Fix `LD_PRELOAD` + `OMNITRACE_DL_VERBOSE=3` issue
- Adds a sampling offload verbose message
- Improves MPI send-recv.cpp example error message
- Minor tweaks to binary library
- `binary::get_linked_path` returns `std::optional<string>`
- renamed `binary::symbol::read_bfd` to `binary::symbol::read_bfd_line_info`
- `binary::get_binary_info` has param options for reading line info and included undefined symbols
- fixed another edge case instance of resource deadlock during first call to configure_settings
- improved the error log printing in `omnitrace` (does not print repeated messages)
* fix OMNITRACE_DL_VERBOSE=3 + preload issue
- join needs to handle nullptr
* sampling offload verbose message
* mpi-send-recv error message
* binary updates
- get_linked_path returns std::optional<string>

* Testing fix for HIP w/o rocprofiler support
- disable rocprofiler tests when HIP enabled but OMNITRACE_USE_ROCPROFILER=OFF
* omnitrace exe: insert_instr nullptr check
* omnitrace exe: new method for determining internal constraints
- added internal-libs.cpp
- using binary::get_binary_info on various known libs used by omnitrace
- any matching func/file from symbols found in known internal libs are excluded
- relaxed restrictions in is_module_constrained
- relaxed restrictions in is_routine_constrained
- added a few safety checks
* internal libs append/remove
- options to change which libs are considered internal libraries
* omnitrace exe instruction exclude
- regex option for excluding functions containing specific instructions
* fix is_internal_constrained
* binary link map verbose message
* support constraints on linkage and visibility of symbols

- multithread processing internal info
- report timing info
* Defer parsing internal data
- wait until after address space is created
* Performance improvement finding for get_symtab_function
* fix data race in get_binary_info
* remove set_default for linkage and visibility argparse
* Parse internal libs with Dyninst::Symtab instead of binary reader
- conflicting versions of libraries for binary analysis causes problems
- expanded whole function restrictions

* internal lib updates
- include memory usage info
- option to read libraries linked against internal libs: --internal-library-deps
- defer parsing internal libs data to when processing modules
