This flag was used to disable test runs during make distcheck. Now that we
have more checks and the environment variable, we can drop this flag.

The tests all need root, but running distcheck as root is not ideal. Disable
the test runs (but not the build) to make it easier to verify distcheck works
as intended.

We put m4 files into a separate directory. If we ever put our own files in
there, we need to include it. Furthermore, this suppresses annoying
autotools warnings.

Doxygen is bad for man pages, but having an online API documentation
is better and easier to maintain.

Two main goals of this library:
- 'transparently' handle SYN_DROPPED events
- avoid errors in ioctl handling by providing a simpler interface.

Keeps a cached copy of the device for quick querying.
