Andrew Werner e2cf734490 aya: Implement RingBuf 
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.

[libbpf]: https://github.com/libbpf/libbpf/blob/master/src/ringbuf.c

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

astoycos 7b71c7e1cd aya/maps: add pin() api 
- Adds new `maps_mut()` API to the BpfManager to allow us to iterate though
and pin all of maps at the same time.

- Adds new pin(Path)/unpin(Path) api to Maps so they
can be generically pinned AFTER load.

- Adds macro for pinning explicit map types in aya.
Convert all explicit map types "inner" field to be
pub crate in order to facilitate this.

Merge pull request #790 from dave-tucker/no-map-pinned 2 years ago
Dave Tucker 938f979fe7 aya: Make MapData::pin pub 
This is to solve a use-case where a user (in this case bpfd) may want
to:

- MapData::from_pin to open a pinned map from bpffs
- MapData::pin to pin that object into another bpffs

Both operations should be easily accomplished without needing to cast
a MapData into a concrete Map type - e.g aya::maps::HashMap.

Dave Tucker 0f4021ec89 aya: Remove MapData::pinned 
BPF objects can be pinned multiple times, to multiple different places.
Tracking whether or not a map is pinned in a bool is therefore not sufficient.
We could track this in a HashSet<PathBuf>, but there is really no reason
to track it at all.

aya: add program_info() api to `Program`
 2 years ago
Tamir Duberstein f41592663c
maps: `MapFd` and `SockMapFd` are owned 
`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.

async_perf_event_array: access inner through async

Andrew Werner 2a1bf609b2 aya/maps: rework TryFrom macros 
The old macros were repetitive and inflexible. This unifies the various

Cleanup in anticipation of fixing #636.

The API changes are just about renaming the return to Self and
Self::Error; they are not real changes.

aya: Use AsFd when attaching fds to programs 
This is a breaking change but adds another level of safety to ensure
the file descriptor we receive is valid. Additionally, this allows
aya to internally easily duplicate this file descriptor using std
library methods instead of manually calling `dup` which doesn't
duplicate with the CLOSE_ON_EXEC flag that is standard pratice to
avoid leaking the file descriptor when exec'ing.

- Add helper methods to get useful information from the ProgramInfo

- 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
