Sysprof has moved to a new ABI which removes GLib from the capture library
so that GLib itself can link against sysprof-capture.
This bumps the library ABI so we can keep things coordinated between all
the new tracing layers in the stack.
Add libasan and libubsan to fedora-base:v20,
and build fedora:20 on top of it.
This is so we can build and run the tests with
the address and undefined behavior sanitizers.
Split the fedora image into fedora-base (containing just
the packages) and fedora (adding the user setup), and add
a fedora-docs image that is adding pandoc on top of the
fedora-base image.
