Felix Lange 6c73a59806 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.

Felix Lange 41b2008a66 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.

obscuren 6244b10a8f core: settable genesis nonce
You can set the nonce of the block with `--genesisnonce`. When the
genesis nonce changes and it doesn't match with the first block in your
database it will fail. A new `datadir` must be given if the nonce of the
genesis block changes.

obscuren d09a6e5421 core, eth, miner: moved nonce management to tx pool.
Removed the managed tx state from the chain manager to the transaction
pool where it's much easier to keep track of nonces (and manage them).
The transaction pool now also uses the queue and pending txs differently
where queued txs are now moved over to the pending queue (i.e. txs ready
for processing and propagation).
