> Changed in v10:
> * Add suggestions by Stefan Hajnoczi:
> * Merge paths in 'do_trace_event_set_state'.
> * Add header guards in "trace/control-internal.h".
> * Remove TODO from docs in 'trace_print_events'.
> * Rename 'glob' in "trace/control.c" as 'pattern_glob'.
> * Implement 'trace_event_is_pattern' in terms of 'strchr'.
> Changes in v9:
> * Rebase on 7cd5da7 from master.
> * Change dynamic tracing state from monitor only in enabled events.
> * Assert dynamic tracing state changes are performed only on enabled events.
> * Split 'trace_event_set_state_dynamic' into a generic and a backend-specific
> part.
> Changes in v8:
> * Rebase on a2685bc from master.
> * Fixed typo in commit message for "trace: Provide a detailed event control
> interface".
> Changes in v7:
> * Rebase on a8a826a from master.
> * Moved compilation & code generation for "trace/" into a separate makefile.
> * Renamed targets and moved rules according to the new makefile structure.
> Changes in v6:
> * Fixed typos in the documentation of the 'TraceEvent' struct.
> Changes in v5:
> * Rebase on dbaf26b3 from master.
> * Always initialize temporary 'ev' in 'trace_backend_init_events'.
> * Make common sanity checks in 'trace_event_set_state_dynamic' and delay
> backend-specific code to 'trace_event_set_state_dynamic_backend'.
> Changes in v4:
> * Documentation fixes and (re)formatting.
> Changes in v3:
> * Add some assertions.
> * Remove debugging printf's.
> * Improve documentation.
> * Make 'trace_event_get_state_static' use run-time information, and leave
> TRACE_*_ENABLED for compile-time checks.
> Changes in v2:
> * Minor compilation fixes.
