eth: limit number of sent transactions based on message size
...
Nodes that are out of sync will queue many transactions, which causes
the initial transactions message to grow very large. Larger transactions
messages can make communication impossible if the message is too big to
send. Big transactions messages also exhaust egress bandwidth, which
degrades other peer connections.
The new approach to combat these issues is to send transactions in
smaller batches. This commit introduces a new goroutine that handles
delivery of all initial transaction transfers. Size-limited packs of
transactions are sent to one peer at a time, conserving precious egress
bandwidth.

eth: limit number of sent blocks based on message size
...
If blocks get larger, sending 256 at once can make messages large
enough to exceed the low-level write timeout.

eth, eth/downloader: Moved block processing & graceful shutdown

The downloader is no longer responsible for processing blocks. The
