2014-05-21perf tools: Consolidate management of default sort ordersNamhyung Kim
The perf uses different default sort orders for different use-cases, and this was scattered throughout the code. Add get_default_sort_ order() function to handle this and change initial value of sort_order to NULL to distinguish it from user-given one.

2014-05-21perf ui: Get rid of callback from __hpp__fmt()Namhyung Kim
The callback was used by TUI for determining color of folded sign using percent of first field/column. But it cannot be used anymore since it now support dynamic reordering of output field. So move the logic to the hist_browser__show_entry().

2014-05-21perf tools: Consolidate output field handling to hpp format routinesNamhyung Kim
Until now the hpp and sort functions do similar jobs different ways. Since the sort functions converted/wrapped to hpp formats it can do the job in a uniform way. The perf_hpp__sort_list has a list of hpp formats to sort entries and the perf_hpp__list has a list of hpp formats to print output result. To have a backward compatibility, it automatically adds 'overhead' field in front of sort list. And then all of fields in sort list added to the output list (if it's not already there).

Currently, the scripts hard-code arch/x86/boot/bzImage, which does not work well for other architectures.

This commit also adds a --bootimage argument that allows selecting some other file, for example, "vmlinux".
