This patch updates the Address type in common/types.go so that the Hex
function provides an EIP55-compliant output string. The implementation is pretty lightweight; 
on my laptop the benchmark gives 1100ns/op, with the majority of that value due to the Keccak hash.

mobile: add RinkebyGenesis method

* core: reduce txpool event loop goroutines and sync structs

* cmd, core, eth: journal local transactions to disk

* core: journal replacement pending transactions too

* core: separate transaction journal from pool

trie: typo in comment

core/vm/runtime: fix evm command to use --gasprice flag value

As per https://golang.org/s/generatedcode. This will allow other tools
such as golint to properly ignore the files.

* node: Rename TrusterNodes

* node: Rename TrusterNodes

cmd/faucet: ignore whitespace in gist content

cmd/puppeth: limit cotnainers to 10MB logs

* mobile: don't retain transient []byte in CallMsg.SetData

Go mobile doesn't copy []byte parameters, for performance and to allow
writes to the byte array be reflected in the native byte array.
Unfortunately, that means []byte arguments are only valid during the
call it is being passed into.

CallMsg.SetData retains such a byte array. Copy it instead

Fixes #14675

* mobile: copy all []byte arguments from gomobile

To avoid subtle errors when accidentially retaining an otherwise
transient byte slice coming from gomobile, copy all byte slices before
use.

* mobile: replace copySlice with common.CopyBytes

* mobile: Use EIP155Signer - closes #14762

* mobile: Correctly fall back on HomesteadSigner when no chainID is passed in

README: get rid of the non-existent disasm command

consensus/ethash, core: implement Metropolis EIP 100

Implements ethereum/EIPs#98
