perf evsel: Rename set_filter to apply_filter
We need to be able to go on constructing a complex filter in multiple stages, since we can only set one filter per event. For instance, we need to be able, in 'perf trace' to filter by the 'common_pid' field all the time, if only for the tracer itself, to avoid a feedback loop, and, in addition, we may want to filter the raw_syscalls:sys_{enter,exit} events by its 'id' filter, when using 'perf trace -e open,close' or 'perf trace -e !open,close', i.e. when we are interested in just a subset of syscalls or when we are not interested in it. So we will have: perf_evsel__set_filter(evsel, char *filter) Replaces whatever is in evsel->filter. perf_evsel__append_filter(evsel, const char *op, char *filter) Appends, using op ("&&" or "||") with what is in evsel->filter. perf_evsel__apply_filter(evsel, filter): That actually applies a filter, be it the one being constructed in evsel->filter, or any other, for tools with more specific ways to build the filter, issuing the appropriate ioctl for all the evsel fds. The same changes will be made to the evlist__{set,apply} variants to keep everything consistent.
