Having separate format hints and tokens per IP address family is
unnecessary, since they are represented by different types and we handle
format hints for each type separately. So we can just have one format
hint.
Also, we should be consistent with the format strings grammar in
Rust[0]. The `type` token, which is mapped to formatting traits, usually
consists of one letter[1] (and optional `?` for `Debug` trait, but that
doesn't matter for us). It shouldn't consist of multiple letters. Our
`:ipv4` and `:ipv6` tokens were clearly breaking that convention, so we
should rather switch to something with one letter - hence `:i`.

Now that bpf-linker uses llvm 16, the easiest way is to use Fedora 38
Beta with the testing repos as they have it, without resorting to
Rawhide.
See https://packages.fedoraproject.org/pkgs/llvm/llvm/.
This commit adds from_pin() which allows the creation of a Program
from a path on bpffs. This is useful to be able to call `attach` or
other APIs for programs that are already loaded to the kernel.
This differs from #444 since it implements this on the concrete program
type, not the Program enum, allowing the user to pass in any additional
context that isn't available from bpf_prog_info.

Before this chane, the check was always negative if the minor version
was less then 9. So, for example, the smoke test was skipped for kernel
6.1:
```
skipping as 6.1 does not meet version requirement of 5.9
```

Simplifiy the relocation tests build process by removing the need for libbpf
at runtime. Its usage is replaced with local `__builtin_*` attributes.
This removes the need for the `LIBBPF_INCLUDE` env variable.
This commit adds documentation on how program names are parsed from
section names, as is used by `aya_obj::Object.programs` as HashMap keys,
and updates the examples into using program names.
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.
