eth_estimateGas returns wrong gas, off by 1.5% about go-ethereum HOT 3 OPEN

I have submitted two permissible solutions for this issue.

• add eth_necessaryGas
• remove ErrorRatio

Which merges should depend upon what the maintainers consider to be correct behavior, and how much they care about standardization.

Neither PR is really a viable one.

• remove ErrorRatio: this undoes the optimization that's useful for everyone but you.
• add necessaryGas: this pollutes the namespace for a method that's not needed by anyone, but you.

Whilst I get your pain, we need a solution that's more flexible that both these extremes. My suggestion towards that would be adding an optional parameter to eth_estimateGas to control the error rate. I don't think any client would be against it, since it is an easy optimization for all to support error rates. The only catch is that we already have the block number as an optional parameter, meaning that anyone specifying the error rate will also need to explicitly specify the block to estimate on top (but latest does work). IMO that would support power users without polluting the namespaces as well as without undoing an optimization everyone - but you - cares about.
