The documentation parts that got approved by Eli didn't change, apart
from a mechanical change that changed ptwrite_listener to ptwrite_filter.

Apart from that I only made some minor changes:
* Changed every mention of ptwrite_listener to ptwrite_filter.
* Made the ptw callback return std::string instead of a 'malloced' char ptr.
* Simplified gdb.exp/skip_btrace_ptw_tests.
* Some minor changes to comments and a couple of other shortcomings in the
the last three patches. The first 7 are unchanged.

Regards,
Felix
