[PATCH v2 0/7] perf ui/browser: Add browser for perf script

[Feng Tang <feng.tang@intel.com>]

Hi Arnaldo and all,

This is a patch set mainly to add a browser for perf script, which
will be integrated into the main hists and annotation browser.

Patch 1-4 are some preparation for adding the script
patch 5 introduce the script browser
patch 6-7 integrate the browser to hists browser and annotation browser

The patches are on top of current perf/core branch of your git tree. 
Please help to review. 

Namhyung,

Many thanks for providing many good comments for the v1 patch sets. In
this v2, I addressed most of those comments, for the suggestion to use
browser for "perf script -l", I'll handle it later, and would post the
v2 first for review.

Changelog:
	Since v1:
	* Add filter for scripts can't be run in script browser
	* Fix some bugs about buffer handling and error check
