Make profiling easier to follow with static dispatch.

For example, when performing a heap profile, this:

         .          .    125:   fetchFunc := db.FetchUnSpentTxByShaList
         .          .    126:   if includeSpent {
         .          .    127:           fetchFunc = db.FetchTxByShaList
         .          .    128:   }
         .     9.11MB    129:   txReplyList := fetchFunc(txList)

Now becomes this:

         .          .    125:   var txReplyList []*database.TxListReply
         .          .    126:   if includeSpent {
         .          .    127:           txReplyList = db.FetchTxByShaList(txList)
         .          .    128:   } else {
         .     8.75MB    129:           txReplyList = db.FetchUnSpentTxByShaList(txList)
         .          .    130:   }

And it's clear where the majority of our allocations are coming from.
