dd11d97cdb Include libbpf_h path in c sched compilation
If a user wants to use an external libbpf source (via libbpf_h opt)
we need to also pass this to c sched compilation.

988b7d13c1 Bump versions
scx_exit_info change doesn't require code to be updated but breaks binary
compatbility. Bump versions and cut a new release.

942b0269b8 Bump versions
After updates to reflect the updated init and direct dispatch API, the
schedulers aren't compatible with older kernels. Bump versions and publish
releases.

05f5c69747 ci: use virtme-ng to test the schedulers
Use virtme-ng to run the schedulers after they're built; virtme-ng
allows to pick an arbitrary sched-ext enabled kernel and run it
virtualizing the entire user-space root filesystem, so we can basically
exceute the recompiled schedulers inside such kernel.

This should allow to catch potential run-time issue in advance (both in
the kernel and the schedulers).

The sched-ext kernel is taken from the Ubuntu ppa (ppa:arighi/sched-ext)
at the moment, since it is the easiest / fastest way to get a
precompiled sched-ext kernel to run inside the Ubuntu 22.04 testing
environment.

The schedulers are tested using the new meson target "test_sched", the
specific actions are defined in meson-scripts/test_sched.

By default each test has a timeout of 30 sec, after the virtme-ng
completes the boot (that should be enough to initialize the scheduler
and run the scheduler for some seconds), while the total lifetime of the
virtme-ng guest is set to 60 sec, after this time the guest will be
killed (this allows to catch potential kernel crashes / hangs).

If a single scheduler fails the test, the entire "test_sched" action
will be interrupted and the overall test result will be considered a
failure.

At the moment scx_layered is excluded from the tests, because it
requires a special configuration (we should probably pre-generate a
default config in the workflow actions and change the scheduler to use
the default config if it's executed without any argument).

Moreover, scx_flatcg is also temporarily excluded from the tests,
because of these known issues:
 - https://github.com/sched-ext/scx/issues/49
 - https://github.com/sched-ext/sched_ext/pull/101

6343bcf360 build: introduce enable_rust build option
Introduce an option to enable/disable the build of all the Rust
sub-projects.

This can be useful to build scx on those systems where Rust is not
fully supported (e.g., armhf).
