This merge commit adds the following code from the github.com/decred/dcrutil package into a new github.com/decred/dcrd/dcrutil package: * Address handling * Amount type * AppDataDir func * bitflags functions * Block wrapper type * Hash160 func * Tx wrapper type * WIF type as well as all tests for this code. The old github.com/decred/dcrutil/hdkeychain package has also been merged and moved to github.com/decred/dcrd/dcrutil/hdkeychain. dcrd packages have been updated to use the new packages and the dep files have been updated for this change.
