Enable seccomp support in `runk` by default.
Due to this, `runk` is built with `gnu libc` by default
because the building `runk` with statically linked the `libseccomp`
and `musl` requires additional configurations.
Also, general container runtimes are built with `gnu libc` as
dynamically linked binaries by default.
The user can disable seccomp by `make SECCOMP=no`.

"inline-virtio-fs" is newly supported by kata 3.0 as a "shared_fs" type,
it should be described in configuration file.
"inline-virtio-fs" is the same as "virtio-fs", but it is running in
the same process of shim, does not need an external virtiofsd process.

Kata 3.0 introduced 3 new configurations under runtime section:

Blank values will lead to starting to fail.
Adding default values will make user easy to migrate to kata 3.0.

Refactor the container builder code (`InitContainer` and `ActivatedContainer`)
to make it easier to understand and to maintain.
The details:
1. Separate the existing `builder.rs` into an `init_builder.rs` and
`activated_builder.rs` to make them easy to read and maintain.
2. Move the `create_linux_container` function from the `builder.rs` to
`container.rs` because it is shared by the both files.
3. Some validation functions such as `validate_spec` from `builder.rs`
to `utils.rs` because they will be also used by other components as
utilities in the future.

Augment the mock hypervisor so that we can validate that ACPI memory hotplug
is carried out as expected.
We'll augment the number of memory slots in the hypervisor config each
time the memory of the hypervisor is changed. In this way we can ensure
that large memory hotplugs are broken up into appropriately sized
pieces in the unit test.

If we're using ACPI hotplug for memory, there's a limitation on the
amount of memory which can be hotplugged at a single time.
During hotplug, we'll allocate memory for the memmap for each page,
resulting in a 64 byte per 4KiB page allocation. As an example, hotplugging 12GiB
of memory requires ~192 MiB of *free* memory, which is about the limit
we should expect for an idle 256 MiB guest (conservative heuristic of 75%
of provided memory).
From experimentation, at pod creation time we can reliably add 48 times
what is provided to the guest. (a factor of 48 results in using 75% of
provided memory for hotplug). Using prior example of a guest with 256Mi
RAM, 256 Mi * 48 = 12 Gi; 12GiB is upper end of what we should expect
can be hotplugged successfully into the guest.
Note: It isn't expected that we'll need to hotplug large amounts of RAM
after workloads have already started -- container additions are expected
to occur first in pod lifecycle. Based on this, we expect that provided
memory should be freely available for hotplug.
If virtio-mem is being utilized, there isn't such a limitation - we can
hotplug the max allowed memory at a single time.

It'll be useful to get the total memory provided to the guest
(hotplugged + coldplugged). We'll use this information when calcualting
how much memory we can add at a time when utilizing ACPI hotplug.

Adds oci under the src/libs workplace.
oci shares a Cargo.lock file with the rest of src/libs but was not
listed as a member of the workspace.
There is no clear reason why it is not included in the workspace, so
adding it so cargo-deny stop complaining
Signed-off-by: Derek Lee <derlee@redhat.com>
One of the checks done by cargo-deny is ensuring all crates have a valid
license. As the rust programs import each other, cargo.toml files
without licenses trigger the check. While I could disable this check
this would be bad practice.
This adds an Apache-2.0 license in the Cargo.toml files.
Some of these files already had a header comment saying it is an Apache
license. As the entire project itself is under an Apache-2.0 license, I
assumed all individual components would also be covered under that
license.
