Jeffrey Wilcke f0cbebb19f core: added basic chain configuration 
Added chain configuration options and write out during genesis database
insertion. If no "config" was found, nothing is written to the database.

Configurations are written on a per genesis base. This means
that any chain (which is identified by it's genesis hash) can have their
own chain settings.

Jeffrey Wilcke 14013372ae core: Added EVM configuration options 
The EVM is now initialised with an additional configured object that
allows you to turn on debugging options.

Jeffrey Wilcke 342ae7ce7d core, core/vm, tests: changed the initialisation behaviour of the EVM 
The EVM was previously initialised and created for every CALL, CALLCODE,
DELEGATECALL and CREATE. This PR changes this behaviour so that the same
EVM can be used through the session and beyond as long as the
Environment sticks around.

Gustav Simonsson e1616f77c7 core, core/vm, cmd/evm: remove redundant balance check 2015-10-06 12:42:34 +02:00
Jeffrey Wilcke 361082ec4b cmd/evm, core/vm, test: refactored VM and core 
* Moved `vm.Transfer` to `core` package and changed execution to call
`env.Transfer` instead of `core.Transfer` directly.
* core/vm: byte code VM moved to jump table instead of switch
* Moved `vm.Transfer` to `core` package and changed execution to call
  `env.Transfer` instead of `core.Transfer` directly.
* Byte code VM now shares the same code as the JITVM
* Renamed Context to Contract
* Changed initialiser of state transition & unexported methods
* Removed the Execution object and refactor `Call`, `CallCode` &
  `Create` in to their own functions instead of being methods.
* Removed the hard dep on the state for the VM. The VM now
  depends on a Database interface returned by the environment. In the
  process the core now depends less on the statedb by usage of the env
* Moved `Log` from package `core/state` to package `core/vm`.

Jeffrey Wilcke 184e9ae9a8 core, tests: reduced state copy by N calls 
Reduced the amount of state copied that are required by N calls by doing
a balance check prior to any state modifications.

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".

Felix Lange be97785856 cmd/evm: add dummy implementation for GetHash 
Fixes the build. AFAIK evm does not bother keeping a chain and
cannot provide a real implementation.
