2a45a494b0 Use block times for 'hard' OP_EVAL switchover, and refactored EvalScript
so it takes a flag for how to interpret OP_EVAL.
Also increased IsStandard size of scriptSigs to 500 bytes, so
a 3-of-3 multisig transaction IsStandard.

e679ec969c OP_EVAL implementation
OP_EVAL is a new opcode that evaluates an item on the stack as a script.
It enables a new type of bitcoin address that needs an arbitrarily
complex script to redeem.

dbbf1d4a48 GetMinFee takes a mode parameter (GMF_{BLOCK,RELAY,SEND}) instead of fForRelay 2011-12-14 01:07:43 -05:00

a880b29cab Bugfix: fForRelay should be false when deciding required fee to include in blocks
During the rushed transition from 0.01 BTC to 0.0005 BTC fees, we took the
approach of dropping the relay and block-inclusion fee to 0.0005 BTC
immediately, and only delayed adjusting the sending fee for the next release.
Afterward, the relay fee was lowered to 0.0001 BTC to avoid having the same
problem in the future. However, the block inclusion code was left setting
fForRelay to true! This fixes that, so the lower 0.0001 BTC allowance is (as
intended) only permitted for real relaying.

074d584a04 Added RPC call 'getmemorypool' that provides everything needed to construct a block with a custom generation transaction and submit a solution
getmemorypool [data]
If [data] is not specified, returns data needed to construct a block to work on:
  "version" : block version
  "previousblockhash" : hash of current highest block
  "transactions" : contents of non-coinbase transactions that should be included in the next block
  "coinbasevalue" : maximum allowable input to coinbase transaction, including the generation award and transaction fees
  "time" : timestamp appropriate for next block
  "bits" : compressed target of next block
If [data] is specified, tries to solve the block and returns true if it was successful.
