rfc: clean it up and optimize

[pulsejet]

My intention is to rip off everything that isn't or is hard to maintain, and hopefully make this more usable.

1. Remove ethernet face
2. Remove face events
3. Remove the UI
4. Remove NDNLP reliability and retransmission
5. Completely rip off the ndn library here, switch to go-ndn instead

Various optimizations

1. Switch to sync.Map
2. GC optimizations
3. Remove pointless goroutines

Benchmark

1. GOMAXPROCS=4 GOGC=400 ./yanfd with one instance of putchunks and 2 instances of catchunks.
2. Goodput goes from ~3gbps to ~4.5gbps

Thank you for your help. This relieves the maintenance burden. But I want to make sure that:

• What is the goal of YaNFD?
• Do we still want to support the Windows App?

What is the purpose of this line?

It's a deep copy. I'm not really sure what is going on here: the underlying array gets deallocated / overwritten somehow if this isn't copied and it becomes garbage. If I remove the copies in this file:

Thank you for clarifying. This seems to be a big issue. Maybe we should add a comment explaining this.

Ethernet face was last maintained in 2024-Aug and is not broken so it should be kept.
No objection in deleting other features.

Thanks for reviewing, Xinyu.

• What is the goal of YaNFD?

I've more stuff planned for the future (which might not materialize). Essentially I want YaNFD to be the out-of-the box NDN daemon that's focuses on ease of use and is maintanable. I'll elaborate in a Saturday call if you're available.

• Do we still want to support the Windows App?

For now, I don't see the point. Some of the stuff that is removed here can be pulled back in later. My priority for this PR is to nuke the YaNFD/ndn package.

If it works then it's probably fine; I'll try to pull this back in.

Then let it die 🙈
TBH I'm kind of tired of satisfying Windows store's policy, which seems to be more strict than COVID days

Let's do it in a separate PR. This is already too large and it seems to be working.
