Miklos Vajna c57d6d39c8 comphelper: allow simple ad-hoc measuring with ProfileZones
And then remove the manual measuring from the RTF import.

Sample output:

comphelper::ProfileZone: RtfFilter::filter finished in 180 ms

* Note that the char pointer is stored as such in the ProfileZone object and used in the
* destructor, so be sure to pass a pointer that stays valid for the duration of the object's
* lifetime.
*
* The second parameter can be used for ad-hoc local measuring by adding a single line of code
* at a C++ scope start. Example:
*
* comphelper::ProfileZone aZone("RtfFilter::filter", true);
*
* Similar to the DEBUG macro in sal/log.hxx, don't forget to remove these lines before
