Dave Tucker b2924a3a26 aya-log: Make miri happy 
Miri took issue about using slice::from_raw_parts without checking for
alignment. Instead, we can simply convert to a [u8;16] into a [u16;8] by
iterating in chunks of 2 and bitshifting (remembering that these arrays
are in network-endian order).

Andrew Stoycos 8a9cbf179f Add `from_pinned` and `from_fd` methods 
Add `from_pinned` to allow loading BPF maps
from pinned points in the bpffs and
`from_fd` to allow loading BPF maps from
RawFds aquired via some other means eg
a unix socket.

These functions return an
aya::Map which has not been used previously
but will be the future abstraction once
all bpf maps are represented as an enum.

Dave Tucker 4b5b9ab3d9 aya: More pinning fixes 
This commit fixes a bug and adds some missing lifecycle APIs.

1. Adds PinnedLink::from_path to create a pinned link from bpffs
2. Adds From<PinnedLink> for FdLink to allow for ^ to be converted
3. Adds From<FdLink> for XdpLink

Michal Rostecki 895f96e971 ebpf: Add TcContext for classifier programs 
This change separates the previous `SkBuffContext` into three structs:

* `SkBuff` which is a wrapper around `__sk_buff` which contains all
  possible methods operating on it.
* `SkBuffContext` which is a program context for programs which
  **cannot** access `__sk_buff` directly and instead can only use
  `load_bytes`.
* `TcContext` which is a classifier context which can access `__sk_buff`
  directly, hence exposes `data` and `data_end`.

Dave Tucker f34ebeba99 aya: Improved BTF Type API 
This commit removes reliance on generated BtfType structs, as
well as adding a dedicated struct for each BTF type. As such,
we can now add nice accessors like `bits()` and `encoding()`
for Int vs. inlined shift/mask operations.

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.
