Felix Lange 3f047be5aa all: update license headers to distiguish GPL/LGPL
All code outside of cmd/ is licensed as LGPL. The headers
now reflect this by calling the whole work "the go-ethereum library".

Jeffrey Wilcke a748afce03 core: txpool listen for ChainHeadEvent instead of ChainEvent
Changed the transaction pool to listen for ChainHeadEvent when resetting
the state instead of ChainEvent. It makes very little sense to burst
through transactions while we are catching up (e.g., have more than one
block to process)

Jeffrey Wilcke 61ca780f3b core: reduce CPU load by reducing calls to checkQueue
* Reduced maxQueue count
* Added proper deletion past maxQueue limit
* Added cheap stats method to txpool

queueCheck was called for **every** transaction instead of:
1. add all txs
2. check queue

previously

1. add txs[i]
2. check queue
3. if i < len(txs) goto 1.

obscuren e79cc42dfe core: moved check for max queue to checkQueue
Moved the queue to check to the checkQueue method so no undeeded loops
need to be initiated or sorting needs to happen twice.

obscuren 21fa29111b core: reduce max allowed queued txs per address
Transactions in the queue are now capped to a maximum of 200
transactions. This number is completely arbitrary.

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).

obscuren d3be1a2719 eth: moved mined, tx events to protocol-hnd and improved tx propagation
Transactions are now propagated to peers from which we have not yet
received the transaction. This will significantly reduce the chatter on
the network.

Moved new mined block handler to the protocol handler and moved
transaction handling to protocol handler.

Implemented a new transaction queue. Transactions with a holes in their

obscuren 6184781b49 Improved transaction pool

* nonce check
