tracing: Use tracing error_log with hist triggers

Browse source

Replace hist_err() and hist_err_event() with tracing_log_err() from
the new tracing error_log mechanism.

Also add a couple related helper functions and remove most of the old
hist_err()-related code.

With this change, users no longer read the hist files for hist trigger
error information, but instead look at tracing/error_log for the same
information.
