eth/downloader: throttling tests are time-sensitive, don't run parallel

common: remove old RLP implementation, Value and ExtPackage

console crash on nil ptr

console: bugfix that causes the console to crash when connection to an endpoint without the personal api enabled

Light state

In order to make this happen, kill all remaining trivial uses of
common/{rlp,value}.go. The non-trivial ones have been updated earlier.

The test chain generated by makeChainFork included invalid uncle
headers, crashing the generator during the state commit.

The headers were invalid because they used the iteration counter as the
block number, even though makeChainFork uses a block with number > 0 as
the parent. Fix this by introducing BlockGen.Number, which allows
accessing the actual number of the block being generated.

p2p: resolve incomplete dial targets

The test expected the timeout to fire after a matcher for the response
was added, but the timeout is random and fired sooner sometimes.

This change makes it possible to add peers without providing their IP
address. The endpoint of the target node is resolved using the discovery
protocol.

This change simplifies the dial scheduling logic because it
no longer needs to track whether the discovery table has been
bootstrapped.

core: tx pool skip price validation for "owned" transactions

eth: fix #2076, where end of hash query was interpreted number query

rpc: optionally passing context argument to rpc v2 api methods

core, eth, node, rpc: port the admin and debug API

Makefile, cmd/geth: support building Android archives

rpc: new RPC implementation with pub/sub support

crypto: "Crypto" -> "crypto" in web3 key format

Makefile, cmd/geth: assemble ios xcode frameworks

accounts/abi: added output parsing & added call mechanism

core: write individual transactions and receipts too on fast sync

p2p: always allow dynamic dials if network not disabled

crypto/secp256k1: remove dependency on libgmp

core: added a new RemovedLogEvent

Turns out we actually don't need it, USE_NUM_NONE works
because we also set USE_FIELD_INV_BUILTIN.

Makefile: support 64bit ARM iOS cross builds
