Add `{:mac}` (for lower-case hex representation) and `{:MAC}` (for
upper-case hex representation) format hints for the `[u8; 6]` type,
which is the standard one in Linux to store physical addresses in.

Instead of returning anyhow>>Result<()> handle errors
'in-place' with unwrap or panic, for more informative
and user-friendly error messages on test failures.
Fixes#421.

Use a struct called TcOptions for setting priority and handle in SchedClassifier attach
struct TcOptions implements the Default trait, so for the simple use
case in which the defaults are acceptable, we can call attach as
follows:
attach(“eth0”, TcAttachType::Ingress, TcOptions::default())
To specify all options:
attach(“eth0”, TcAttachType::Ingress, TcOptions { priority: (50), handle: (3) })
Or, some options:
attach(“eth0”, TcAttachType::Ingress, TcOptions { priority: (50), ..Default::default() })

Implements step 1 of https://github.com/aya-rs/aya/issues/414.
- Adds handle to the SchedClassifier attach API
- Saves handle in the TcLink sruct and uses it when detaching programs
NOTE: this changes the API, so it will require a bump in the Aya version.

Fix some broken rust doc links.
Make sure rustdoc build fail on warnings
so we catch these broken links in CI.

switch map() and map_mut() from returning a
`Result` to an `Option` since it's just getting
a value from a Hashmap, and to stay in line with
the Programs API.
Remove `MapError::MapNotFound`

Respond to more review comments:
Revert to try_from in doctests so we don't need
to explicitly specify type parameters.
Fixup some documentation
Remove explit types in `try_from` methods

Implement Copy for MapData so that
when `take_map` is used we create a
1 to 1 mapping of MapData to internal
FileDescriptor. This will ensure
that when MapData is used in multiple
tasks that we don't drop the FD before
all tasks are done using it.

Create a new type called `SockMapFd` which is
solely used when a program needs to attach
to a socket map. In the future this same
tatic could be used for other use cases
so we may make this more generic.

Build completing tests passing
Refactor the Map API to better align
with the aya programs API. Specifically
remove all internal locking mechanisms
and custom Deref/DerefMut implementations.
They are replaced with a Map enum
and AsRef/AsMut implementations.
All Try_From implementations have been moved
to standardized enums, with a slightly
special one for PerfEventArray's.
Also cleanup/fix all associated tests and
documentation.

Following the lead of crates like tokio and nix, we now annotate APIs
that require optional features. This helps in cases where a user wants
to have an `AsyncPerfEventArray` which is documented on crates.io, but
it's not obvious that you have to enable the `async` feature.

We often need to wait a bit until the program or link gets unloaded
after dropping.
Also, using a macro makes it clear in which particular test the panic
happened.

libbpf 1.0 doesn't support multimaps defined in `maps` section, it
supports only BTF maps.
At the same time, we already test multimaps loading with the Rust
example (`integration-ebpf/src/bpf/map_test.rs`), so we can just remove
the failing C test.

`override_syscall` performs integer-to-pointer conversion. This is
considered harmful on the newest Rust nightly which provides
`ptr::from_exposed_addr`, but there is no other way on Rust stable than
doing `as *const T`, which is what miri is unhappy about.
