* _S_IREAD works only for file not directories
* use c_utililties functions
* add todo to use c_utility/concat rather that snprintf
* remove now unnecessary stat include
* use backslash separator for path on windows
* duh
* update c_utilities imports and functions signatures
* use c_utilities to concatenate paths
* print debug msg to stdout
* suppress warning, put sros env var as static at the beginnign of the file
* pass local namespace
* more c_utilities renaming
* comment out debug prints for now
* add env vars for security strategy and enforce them
* use rmw_node_security_options structure
* line length
* remove unused conditional
* rename environment variable
* style
* use defines for env var names and use rcutils_stringify on it
* remove unnecessary assignment
* consistent define naming for environment variables names
* stringify SECURITY_ROOST_DIRECTORY
* fix documentation of expand_topic_name()
* use expand_topic_name() in pub/sub/client/service
* update test expectations
* use absolute topic names to avoid mismatch due to expansion
* propagate new functions from rcutils error handling
* convert given rcl allocator to a rcutils allocator
* update to use new rmw function name
* add rcl_validate_topic_name()
* add rcl_expand_topic_name()
* gcc couldn't handle the init lists with tuples
* uncrustify and cpplint
* fix signed compare warnings
* address comments
* organize the substitution string constants together at the top of the file
* comment
* moved allocator to c_utilities
* moved error_handling to c_utilities
* refactor uses of RCL_SET_ERROR_MSG with allocator
* add missing guard condition functions and tests
* add missing timer functions
* refactor rcl_lifecycyle
* missed an instance of RCL_SET_ERROR_MSG
* fix segfaults in error cases for rcl_lifecycle
* remove extra header
* check return code of rcl_lifecycle_init_default_state_machine
* add concept of node namespace to rcl API
also validate node name and node namespace
* name_space -> namespace_
* doc clarification
* make use of rmw_validate_namespace()
* clear expected error messages in test_node.cpp
* avoid unused invalid_index
* include the validation result value when it is unknown
