> 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

> 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
