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

Makefile: enable 64-bit ARM builds on Linux

crypto, crypto/secp256k1: use libsecp256k1 for scalar multiplication

accounts: increase re-lock timeout to account for slow CI servers

Makefile: build ARM v5/v6/v7, drop high API mobile clients

Trie error handling

cmd/utils: restore starting geth without any accounts and etherbase

When a chain reorganisation occurs we collect the logs that were deleted
during the chain reorganisation. The removed logs are posted to the
event mux indicating that those were deleted during the reorg.

Also remove some duplication around address/index parsing.

eth package creates new event mux
