This doesn't add any value; use `cargo build --tests` with
`--message-format=json` instead; parse the output using `cargo_metadata`
to discover the location of the test binary.
Move test/integration-test/src/tests -> test/integration-test/tests to
conform to
https://doc.rust-lang.org/book/ch11-03-test-organization.html#integration-tests .

bpf: improve bpf_probe_read_kernel_str_bytes and bpf_probe_read_user_str_bytes
...
This change does a few things:
- it fixes a bug in the wrappers, where we were expecting the kernel to
return len=1 for b"\0" where it instead returns 0 and doesn't write
out the NULL terminator
- it makes the helpers more robust by hardcoding bound checks in
assembly so that LLVM optimizations can't transform the checks in a
way that the verifier can't understand.
- it adds integration tests

aya: Make Features part of the public API
...
This commit adds a new probe for bpf_attach_cookie, which would be used
to implement USDT probes. Since USDT probes aren't currently supported,
we this triggers a dead_code warning in clippy.
There are cases where exposing FEATURES - our lazy static - is actually
helpful to users of the library. For example, they may wish to choose to
load a different version of their bytecode based on current features.
Or, in the case of an orchestrator like bpfd, we might want to allow
users to describe which features their program needs and return nice
error message is one or more nodes in their cluster doesn't support the
necessary feature set.
To do this without breaking the API, we make all the internal members of
the `Features` and `BtfFeatures` structs private, and add accessors for
them. We then add a `features()` API to avoid leaking the
lazy_static.

aya: Remove iter_key from LPM Trie API
...
Based on the discussion in Discord we've decided to drop the
iter_key() API for LPM Trie. According to the kernel self-tests and
experimentation done in Aya, providing a key into bpf_map_get_next_id
will either:
- If key is an EXACT match, proceed iterating through all keys in the
trie from this point
- If key is NOT an EXACT match, proceed iterating through all keys in
the trie starting at the leftmost entry.
An API in Aya could be crafted that gets the LPM match + less specific
matches for a prefix using these semantics BUT it would only apply to
userspace. Therefore we've opted out of fixing this.

These two functions are needed because kernel symbols representing

These are the equivalent of bcc's get_syscall_fnname and
