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.

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`

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.

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.

1. Removes OwnedLink
2. Allows Links to be converted into FdLink
3. Introduces a PinnedLink type to handle wrap FdLink when pinned and
support un-pinning

This commit allows for BTF maps in the .maps ELF section to be parsed.
It reads the necessary information from the BTF section of the ELF file.
While the btf_ids of Keys and Values types are stored, they are not (yet)
used.
When creating a BTF map, we pass the btf_key_type_id and
btf_value_type_id.

This commit replaces the existing RTF test runner with a simple rust
binary package called - integration-test.
integration-test depends on integration-ebpf, which contains test eBPF
code written in Rust and C. `cargo xtask build-integration-test-ebpf`
can be used to build this code and supress rust-analyzer warnings. It
does require `bpf-linker`, but that is highly likely to be available to
developers of Aya. It also requires a checkout of `libbpf` to extract
headers like bpf-helpers.h.
Since everything is compiled into a single binary, it can be run
be run locally using `cargo xtask integration-test` or remotely using
`./run.sh` which re-uses the bash script from the old test framework
to spawn a VM in which to run the tests.
