279308288c blockchain: Provide new IsCoinBaseTx function. 
This commit adds a new function to the blockchain package named
IsCoinBaseTx which performs the same function as IsCoinBase except it
takes raw wire transactions as opposed to the higher level util
transactions.

While here, it also adds a file for benchmarks along with a couple of
benchmarks for the IsCoinBase and IsCoinBaseTx functions.

Finally, the function was very slightly optimized:

BenchmarkIsCoinBaseOld  100000000  10.7 ns/op  0 B/op  0 allocs/op
BenchmarkIsCoinBaseNew  200000000  6.05 ns/op  0 B/op  0 allocs/op

65eb8020d2 blockchain: Determine script flags sooner. 
This commit moves the definition of the flags which are needed to check
transaction scripts higher up the call stack to pave the way for adding
support for v3 blocks.  While here, also spruce up a couple of sections.

There are no functional changes in this commit.

b40a6f86ef blockchain: Just fetch the height 
We only care about the height, so just fetch the height instead of
the entire block.

fc8dae49e4 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.

b69a849114 Import btcchain repo into blockchain directory. 
This commit contains the entire btcchain repository along with several
changes needed to move all of the files into the blockchain directory in
order to prepare it for merging.  This does NOT update btcd or any of the
other packages to use the new location as that will be done separately.

- All import paths in the old btcchain test files have been changed to
  the new location
- All references to btcchain as the package name have been changed to
  blockchain
