Remove pools for nodes and IDs
This removes the allocation pools for nodes and IDs. I feel they aren't
really needed. Benchmarks:

Refactor crypto layer, switch HMAC for Poyl1305-AES
HMAC-SHA256 calls SHA256() twice which is very expensive. Therefore,
this commit uses Poly1305-AES instead of HMAC-SHA256.
