Michal Rostecki 83ec27f06b lib: Add display hints 
This change adds optional display hints:

* `{:x}`, `{:X}` - for hex representation of numbers
* `{:ipv4}`, `{:IPv4}` - for IPv4 addresses
* `{:ipv6}`, `{:IPv6}` - for IPv6 addresses

It also gets rid of dyn-fmt and instead comes with our own parser
implementation.

Dave Tucker 64f8a434d2 aya: Implement FdLink::pin() 
This allows for FdLinks to also be pinned to BpfFs.
In order for it to be called, the user would first call
`take_link` to get the underlying link. This can then
be destructured to an FdLink where FdLink::pin() may be called.

Dave Tucker dc31e11691 Re-organize into a single workspace 
This commit moves the aya-log projects from the subtree and adds them to
the main cargo workspace. It also brings the BPF crates into the
workspace and moves the macro crates up a level since they aren't BPF
code.

Miri was disabled for aya-bpf as the previous config wasn't actually
checking anything.

CI, clippy, fmt and release configurations have all been adjusted
appropriately.

CI was not properly running for other supported arches which was also
ixed here.

Michal Rostecki 28abaece2a Fix the log buffer bounds 
Change 821ba0b243fd removed the `size > buf.len()` check, which was a
mistake, because we might write to a subslice of the whole buffer, so
then `buf` can be lower than `LOG_BUF_CAPACITY`.

This change compares `size` with `min::(buf.len(), LOG_BUF_CAPACITY)`
instead.

Michal Rostecki 2e0702854b Ensure log buffer bounds 
This change adds checks in `TagLenValue.write()` to ensure that the size
of written data doesn't exceed the buffer size.

Verifier in recent kernel versions requires the bound to be a constant
value, so using `buf.len()` does not work.

Michal Rostecki 628b473e09 ebpf: Ensure the bounds of log buffer 
eBPF verifier rejects programs which are not checking the bounds of the
log buffer before writing any arguments. This change ensures that
written log arguments.

In practice, it means that doing this kind of checks is not going to be
needed in eBPF program code anymore:
