sysprof: fixed row height and text labels
...
This makes things look a bit more like flamegraphs.pl in the sense that we
have some labels and separation between rows. Also, use a ScrolledWindow so
that we can have much taller graphs to accommodate deep stack traces.
We might want to jump to the bottom at some point, but this gets things in
place for now. Icicle graphs are another option (invert).

sysprof: sort flamegraph alphabetically for X axis

This is what flamegraph.pl does, and there is somewhat an expectation that
we match that.

sysprof: use Flamegraph for naming

That is a closer match to callgraph, and the original name anyway.

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.
