The goal here is to avoid having to hard code what visualizers are shown from the .ui files. We just should add things that we find are supported. Long term, I think we'll add a concept of an "instrument" which is the combination of a data source (SpSource) and a visualizer (SpVisualizerRow). The other goal here is to enable the future support for discovering marks and adding rows for each of those threads.
Sysprof is a sampling profiler that uses a kernel module to generate
stacktraces which are then interpreted by the userspace program
"sysprof".

Debugging symbols
- The programs and libraries you want to profile should be compiled
with -fno-omit-frame-pointer and have debugging symbols available,
or you won't get much usable information.
Building Sysprof
----------------
You need some packages installed. The package names may vary depending on your
distribution, the following command works on Fedora 25:
sudo dnf install gcc gcc-c++ ninja-build gtk3-devel
Then do the following:
meson --prefix=/usr build
cd build
ninja
sudo ninja install
WARNING: `ninja install` will mostly install under the configured install
prefix but installs systemd service configuration directly in the system
default location `/usr/lib/systemd` so it won't work without root privileges,
even if the install prefix is a user-owned directory.
