They were unused and their tests failed on Windows.

Not closing the table used to be fine, but now the table has a database.

core, miner: added difficulty bomb

miner: fixed worker race condition

miner: gas limit strategy, target 3141592 & def gas price 50 Shannon

fdtrack: hack to track file descriptor usage

jsre: leave out lines from history possibly containing passwords

cmd, core, eth: support for the olympic network

Package fdtrack logs statistics about open file descriptors.
This should help identify the source of #1549.

Added a --olympic flag which initialiser the olympic protocol settings

The disk stats file was not closed after reading.

The JSON-RPC server wraps TCP connections in order to be able to shut
down them down when RPC is stopped. This is rather scary code. Go 1.3
introduced the http.Server.ConnState hook for such purposes. We can use
this facility now that we depend on Go 1.4.

There are multiple reasons for the switch apart from making the code
less scary:

* the TCP listener no longer ticks every second to check a channel
* pending requests are allowed to finish after stopping the server
* we can time out idle keep-alive connections

Update ethtest default path for BlockTests

accounts: bump timeout in TestSignRace

core: added a running flag to prevent panics in the chainmanager

core: added default genesis block

When a user runs a freshly setup geth w/o a database initialised the
default genesis block is decoded and inserted in to the database.

Old transaction after resend was not removed from pool

This should fix the flakeyness.

Improved error handling for NewTransactionFromBytes

The running flag will determine whether the chain manager is still
running or not. This will prevent the quit channel from being closed
twice resulting in a panic. This PR should fix this issue.

Closes #1559

core/state: Set log index. Closes #1226

rpc/api: add missing autocomplete commands

remove elliptic.P224 usage

Fedora/RedHat distros comply with US patent law and remove this curve,
which makes it impossible to run ethereum with distro provided Golang.

File crypto/ecies/README claims it is unsupported anyway.

rpc: to in eth_call no longer required. Fixed eth_estimateGas

eth, eth/downloader: don't report stall if fetcher filled the block

tests: updated
