Is this just the same as a bad parameter error code?

I believe we have a function already for converting rmw errors to rcl errors

I think overall our error types still need to be better defined.

There are far fewer RMW_RET_* types than RCL_RET_* types. Getting a rcl_ret_t from a rmw_ret_t feels like rcl_ret_t isn't living up to its potential.

Where is this used? Is there a reason we need to expose the rmw layer above the rcl layer?

Looks like it is not used anywhere. But neither is rcl_subscription_get_rmw_handle(). However, rcl_publisher_get_rmw_handle() is used in rclcpp...

Let's just leave it here for now.

Apparently, this function is needed by the SET_ADD_RMW macro in wait.c.

Seems a little odd that we're diverging rcl_take_event and rmw_take_event in terms of having the extra parameter to determine if something was actually taken. Why can't they both work the same.

On second thought, it looks like the other rmw_take() functions also have this extra taken boolean. We should probably leave it in there to be consistent.

Fix leak in test_logging_macros.cpp (ros2#152)
31e4a02 
Call rcutils_logging_shutdown() in TearDown
to avoid leaking logging internal objects.

As any change to this file makes test_logging_named
fail, this releaxes the EXACT_EQ call on
g_last_log_event.location->line_number[1]. Instead
of looking for a particular value, we test an invariant
of the field (line numbers are positive).

Finally, in test_logging_function, initialize g_counter
and g_function_called values to make sure the test will
not fail even if `--gtest_repeat=2` is passed.

Other tests are still failing when this flag is passed:
[  FAILED  ] TestLoggingMacros.test_logging_once
[  FAILED  ] TestLoggingMacros.test_logging_skipfirst
[  FAILED  ] TestLoggingMacros.test_logging_skipfirst_throttle

However, fixing those tests would require actually changing
the logging implementation which is out of the scope of this
change.
