* split CPrivateSend: - common client/server base data structures/functions: CPrivateSendBase - singleton-like helper: CPrivateSend * GetCollateralAmount(), more of GetSmallestDenomination() * refactor GetDSTX * remove excessive static_cast<bool> * bring back LOCK(cs_mapdstx) :) * address review comments * fix bool operator
