* eth/protocols/snap: don't include empty snapshot slot slice
This PR fixes the snapshot storage serving handler. In snap protocol
the response is capped by the response size. Server can cutdown the
response if the accumulated byte size exceeds the local hard limit.
It means we can meet a special scenario that there is no storage slot
included for a requested account, but we attach the proof for this
account by mistake.
So in the prover side, when it meets a empty storage response but with
a valid proof proves there are some more slots left in the trie, then
requestor will reject this response and disconnect with server.
In this PR, if there is no storage slot served for the requested account,
then no proof should be attached as well.

This change makes use of the new code generator rlp/rlpgen to improve the
performance of RLP encoding for Header and StateAccount. It also speeds up
encoding of ReceiptForStorage using the new rlp.EncoderBuffer API.
The change is much less transparent than I wanted it to be, because Header and
StateAccount now have an EncodeRLP method defined with pointer receiver. It
used to be possible to encode non-pointer values of these types, but the new
method prevents that and attempting to encode unadressable values (even if
part of another value) will return an error. The error can be surprising and may
pop up in places that previously didn't expect any errors.
To make things work, I also needed to update all code paths (mostly in unit tests)
that lead to encoding of non-pointer values, and pass a pointer instead.

This change extracts the peer QoS tracking logic from eth/downloader, moving
it into the new package p2p/msgrate. The job of msgrate.Tracker is determining
suitable timeout values and request sizes per peer.
The snap sync scheduler now uses msgrate.Tracker instead of the hard-coded 15s
timeout. This should make the sync work better on network links with high latency.
