2014-03-14perf ui/tui: Reuse generic __hpp__fmt() codeNamhyung Kim
The __hpp__color_fmt used in the TUI code can be replace by the generic code with small change in print_fn callback. And it also needs to move callback function to the generic __hpp__fmt(). No functional changes intended.

2014-01-13perf evlist: Introduce evlist__for_each() & friendsArnaldo Carvalho de Melo
For the common evsel list traversal, so that it becomes more compact. Use the opportunity to start ditching the 'perf_' from 'perf_evlist__', as discussed, as the whole conversion touches a lot of places, lets do it piecemeal when we have the chance due to other work, like in this case.

Based on perf report/top/scripts browser integration idea from acme. This will enable user to runtime switch the data file, when this option is selected, it will popup all the legal data files in current working directory, and the filename selected by user is saved in the global variable "input_name", and a new key 'K_SWITCH_INPUT_DATA' will be passed back to the built-in command which will perform the switch.

2013-01-31perf report: Show group description when event group is enabledNamhyung Kim
When using event group viewer, it's better to show the group description rather than the leader information alone. If a leader did not contain any member, it's a non-group event.

The perf annotate browser on TUI can identify a jump target for a selected instruction. It assumes that the jump target is within the function but it's not the case of PLT symbols which have offset out of the function as a target. Since it caused a segmentation fault, do not try to follow jump target on the PLT symbols.

Please be noted: current script browser is only for report use, and doesn't cover the record phase, IOW it must run against one existing perf data file. The work flow is, users can use function key to list all the available scripts for current perf data file in system and chose one, which will be executed with popen("perf script -s xxx.xx",) and all the output lines are put into one ui browser, pressing 'q' or left arrow key will make it return to previous browser.
