b9cb78a705 profview: View source code of functions with samples inline.
If profiling is done with --log-source-code profview will now display
a "View source" link for each function in the tree view. Clicking this
will show a new source viewer, with sampled lines highlighted. See the
associated bug for screenshots.

This patch also fixes a bug in the profiler where the source info of
only the first code object for each function would be logged, and
includes some refactoring.

65a07b7a10 [tools/profview] Add individual function timeline view
Adds a bar below the current timeline view which can show the time
when an individual function was on the stack. Functions in the call
stack are now clickable to show them in this view.

Sections where the function was on the stack, but not at the top, are
displayed at half height.

437dece4d9 [profiler] This adds function butterflies to the function list.
The function list is now filtered by category by default, and sorting improved to break ties better.

Since the butterfly trees get massive, I had to start expanding the call trees on demand. This is implemented by keeping track of all ticks that cross given tree node (+ position where they crosses it). This seems to work quite well - in subsequent CL, I am planning to flip the bottom-up and top-down trees to use this.
