within it.

libsysprof: always increment count for callgraph nodes
...
This shouldn't affect categorizing because that only uses the value if
is_toplevel. But with this added, we can use the count for weights in
other tooling w/o needing augmentation.

libsysprof: sort frames with timsort
...
These are largely pre-sorted, but not fully when you have merged data. This
uses timsort to speed that up a bit.
In particular, the comparison of various sorts break down to (for a
~32,000,000 record capture.
g_array_sort_with_data() => 3.9 seconds
qsort_r() = > 3.7 seconds
gtk_tim_sort() => .79 seconds

The goal here is to allow us to look at way fewer items in a model rather
than every item. For example, we don't want to draw 32,000,000 stack
traces in the overview chart.
