perf report: Find the inline stack for a given address
It would be useful for perf to support a mode to query the inline stack
for a given callgraph address. This would simplify finding the right
code in code that does a lot of inlining.
The srcline.c has contained the code which supports to translate the
address to filename:line_nr. This patch just extends the function to let
it support getting the inline stacks.
It introduces the inline_list which will store the inline function
result (filename:line_nr and funcname).
If BFD lib is not supported, the result is only filename:line_nr.
