This avoids making the project depend on all its dependencies, some of
which are optional, when being built as a Meson subproject.

This allows consumers to get a RAPL profiler object on the D-Bus at
org.gnome.Sysprof3 with path /org/gnome/Sysprof3/RAPL. This can be used
by the clients to record extra power statistics.
It requires the `turbostat` program to be installed, and is provided in
packages such as `kernel-tools` on Fedora. Distributions may want to
ensure that is available as a dependency of Sysprof, but it is not
strictly required.
As we gain in usage, we need to be more careful about using a prefix
that will not collide with other symbols. So version 3 of our ABI will
change to using Sysprof/SYSPROF/sysprof as the various prefixes.
The soname/api version bump will happen later on this branch so that
things are easier to test up until then.
This moves everything into other places and simple includes the
files in the cases that it is necessary. In the future, we can
rewrite sysprofd to use GDBus and add GetProcFile() to allow
for client-side processing of kallsyms.
The big thing going on here is that we are going to split up the libraries
a bit better, and remove GObject from the capture library. The libsysprof
library will bring in the capture library statically, so we can export the
symbols we want.
Eventually, we will bump the version to sysprof-3, but not yet.
