IP address types are available in `core`, so they can be used also in
eBPF programs. This change adds support of these types in aya-log.
* Add implementation of `WriteTuBuf` to these types.
* Support these types in `Ipv4Formatter` and `Ipv6Formatter`.
* Support them with `DisplayHint::Ip`.
* Add support for formatting `[u8; 4]`, to be able to handle
`Ipv4Addr::octets`.

And BpfLoader to EbpfLoader.
This also adds type aliases to preserve the use of the old names, making
updating to a new Aya release less of a burden. These aliases are marked
as deprecated since we'll likely remove them in a later release.

This moves the path dependencies back into the per-crate Cargo.toml.
It is required such that the release tooling can correctly calculate
which version constraints require changing when we perform a release.

When comparing `local_spec` with `target_spec` for enum relocations,
we can encounter a situation when a matchinng variant in a candidate
spec doesn't exist.
Before this change, such case wasn't handled explicitly, therefore
resulted in returning currently constructed `target_spec` at the
end. The problem is that such `target_spec` was, due to lack of
match, incomplete. It didn't contain any `accessors` nor `parts`.
Later usage of such incomplete `target_spec` was leading to panics,
since the code operating on enums' `target_spec` expects at least
one `accessor` to be available.

Implement pinning for perf_event_array and async_perf_event_array.
Additionally make the core MapData.pin method operate on a reference
rather than a mutable reference.

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:

This implements the userspace binding for RingBuf.
Instead of streaming the samples as heap buffers, the process_ring
function takes a callback to which we pass the event's byte region,
roughly following [libbpf]'s API design. This avoids a copy and allows
marking the consumer pointer in a timely manner.

Additionally, integration tests are added to demonstrate the usage
of the new APIs and to ensure that they work end-to-end.

`MapData::fd` is now a `MapFd`. This means that `MapData` now closes the
file descriptor on drop. In the future we might consider making `MapFd`
hold a `BorrowedFd` but this requires API design work due to overlapping
borrows.
Since `SockMapFd` is no longer `Copy`, attach methods to take it by
reference to allow callers to use it multiple times as they are
accustomed to doing.
`SockMapFd` implements `try_clone`. `MapFd` and `SockMapFd` are now
returned by reference to allow callers to avoid file descriptor cloning
when desired.
This is an API breaking change.
Updates #612.
The primary driver of change here is that `MapData::create` is now a
factory function that returns `Result<Self, _>` rather than mutating
`&mut self`. The remaining changes are consequences of that change, the
most notable of which is the removal of several errors which are no
longer possible.
- Add helper methods to get useful information from the ProgramInfo
object which is returned by the `loaded_programs()` API. Specifically
this code mirrors the `bpftool prog` command in terms of useful fields.
- Add a new API macro to each aya `Program` type to allow us to fetch
its accompanying `ProgramInfo` metadata after its been loaded.
- Add a new ProgramInfo constructor that builds a new instance using
a raw fd.
- Add a smoke test for the loaded_programs() API as well as
all the relevant methods on the ProgramInfo type.
