Adds missing libelf headers that are now included
as part of libbpf-internal.h. Adds ppc64el and
s390x to the cross environment.

Force bpf-linker to always be rebuilt/relinked. Before this change we
were always installing latest llvm from brew, but not always rebuilding
bpf-linker, which could lead to:
Run cargo install bpf-linker --git https://github.com/aya-rs/bpf-linker.git --rev 821f92990074cb7e950e25129dcd55e20424cede --no-default-features
Updating git repository `https://github.com/aya-rs/bpf-linker.git`
Ignored package `bpf-linker v0.9.10 (https://github.com/aya-rs/bpf-linker.git?rev=821f92990074cb7e950e25129dcd55e20424cede#821f9299)` is already installed, use --force to override
And then:
warning: integration-test@0.1.0: error: linking with `bpf-linker` failed: signal: 6 (SIGABRT)
warning: integration-test@0.1.0: = note: dyld[17642]: Library not loaded: '/usr/local/opt/z3/lib/libz3.4.12.dylib'

This adds a linter to catch common markdown formatting errors.
The linter used is markdownlint-cli2 which is available on all platforms
and has an associated Github Action to automate these checks in CI.
Configuration is checked in at .markdownlint-cli2.yaml.
You may run the check locally using `markdownlint-cli2`.
Or you may install the extension for VSCode:

Implements running integration tests on multiple VMs with arbitrary
kernel images using `cargo xtask integration-test vm ...`.
This changes our coverage from 6.2 to 6.1 and 6.4.
Move the use of clang and llvm-objcopy from run-time to build-time. This
allows the integration tests to run on VMs with simpler userlands.
Create a new CI job to build the integration tests separately from
running them. Ship them from that job to the runner job using github
actions artifacts.
Adds cargo-public-api. This allows for public API changes to get caught
in CI, requiring new changes to be "blessed" by using:
cargo xtask public-api --bless
When this file is changed for aya, Alessandro will need to review the PR.

In release, the trigger functions were being optimized out and the
tests did not work. Use core::hint::black_box to ensure that the
functions are not optimized out. Also, run these integration tests
in CI to ensure that we don't regress.
Trampoline cargo-in-cargo stdio through cargo:warning to ensure the user
sees all the output.
Use bpf-linker from git in CI so we can see what's going on there.
This gives a better view of the CI pipeline in Github.
Gives us control over what runs and when.
And finally, lets us check only a single status in mergify.

This works now that build.rs does the right thing.
Update the `miri test` command in the lint job so it has the proper
exclusions; it is now in line with the invocations in the build-test job.
This feature is equivalent to async_tokio || async_std; removing it
avoids warnings emitted during `cargo hack check --feature-powerset`
where async is selected without either of the other features.
Use cargo hack to ensure clippy runs on the powerset of features.
Use the environment variable AYA_BUILD_INTEGRATION_BPF to indicate to
the build script that it should *actually* build bpf, otherwise emitting
empty files.
This allows metadata builds to skip costly build steps without
sacrificing ergonomics; all compile-time tools such as cargo clippy work
out of the box.
Cargo even gives each of these builds (depending on the value of the
environment variable) its own cache key, so they do not invalidate each
other when the user alternates between metadata and real builds.
This allows the lint action to move out of the VM.
- Add libbpf as a submodule. This prevents having to plumb its location
around (which can't be passed to Cargo build scripts) and also
controls the version against which codegen has run.
- Move bpf written in C to the integration-test crate and define
constants for each probe.
- Remove magic; each C source file must be directly enumerated in the
build script and in lib.rs.
