Subject[PATCH v2 1/3] perf script python: Move dsoname code to a new function
Date
This patch creates a new function get_dsoname() and move the
code which gets the dsoname string to this function.

That's because in next patch, when we process LBR data, we will
also need get_dsoname() to return dsoname for branch from/to.
