Update Heimdall to also use eBPF iterators
...
This eliminates another set of syscalls per cycle. The old per_cpu
map system is now removed, in favor of direct iteration of maps.

Now that we're differentiating between single-CPU and per-CPU map types, we can eliminate 8 bytes of bus traffic by not reporting CPU counts (and padding)

Add a little padding to the output stream kernel side, to nicely align on 64-bit boundaries. Then use aligned casting for zero-copy userspace access to the data. Another smallish speed increase.

Handle per-CPU maps correctly in eBPF iterators
...
The eBPF iterator interface is now per-CPU aware, and correctly
extracts a slice of data for each per-CPU map (or a slice of 1
when using a non-CPU divided map).

Use eBPF iterators (requires kernel 5.8+) instead of next_entry
...
Replaces the eBPF interface "bpf_map_get_next_key" followed by
"bpf_map_lookup_elem" cycle for iterating maps with a call to
the kernel-provided eBPF iterator service.
Currently only implemented for throughput and RTT tracking.
Further commits will tighten the scope and eventually remove
the legacy setup completely.
For 10k hosts, this reduces the number of system calls from
20,002 to 4. The remaining items are a futex lock (required
for safety), and an iterator call.

Add a tool to track eBPF map performance
...
New tool: lqos_map_perf is included in the distribution. It
runs the two map iterators that pound the lqosd/eBPF system
with map iterations, counts the number of entries returned
and reports on overall performance (in µs).
This is intended to help with diagnosing map reading
performance issues and act as a bench-test to see if
using eBPF iterators actually helps.

Hotfix: handle node "type" entry
...
Adding "type" to `network.json` is awesome, but it broke a bit of
Rust. This patch adds support for the `type` field, and fixes
a rare "none" issue that mostly seems to affect my UISP setup.
