tools lib fd array: Allow associating an integer cookie with each entry

2014-09-25T19:46:55Z

We will use this in perf's evlist class so that it can, at fdarray__filter() time, to unmap the associated ring buffer. We may need to have further info associated with each fdarray entry, in that case we'll make that int array a 'union fdarray_priv' one and put a pointer there so that users can stash whatever they want there. For now, an int is enough tho. v2: Add clarification to the per array entry priv area, as well as make it a union, which makes usage a bit longer, but if/when we make it use more space by allowing per entry pointers existing users source code will not have to be changed, just rebuilt.

tools lib api: Adopt fdarray class from perf's evlist

2014-09-25T19:46:55Z

The extensible file description array that grew in the perf_evlist class can be useful for other tools, as it is not something that only evlists need, so move it to tools/lib/api/fd to ease sharing it. v2: Don't use {} like in: libapi_dirs: $(QUIET_MKDIR)mkdir -p $(OUTPUT){fs,fd}/ in Makefiles, as it will not work in some systems, as in ubuntu13.10. v3: Add fd/*.[ch] to LIBAPIKFS_SOURCES (Fix from Jiri Olsa) v4: Leave the fcntl(fd, O_NONBLOCK) in the evlist layer, remains to be checked if it is really needed there, but has no place in the fdarray class (Fix from Jiri Olsa) v5: Remove evlist details from fdarray grow/filter tests. Improve it a bit doing more tests about expected internal state.
