288000a8af storage: drop useless nil assignment in leveldb code
golint suggests:
   Line 24: warning: should drop = nil from declaration of var opts; it is the zero value (golint)

78861485b6 storage: simplify MemoryBatch
It's used a lot and it looks a lot like MemoryStore, it just needs not to
return errors from Put and Delete, so make it use MemoryStore internally with
adjusted interface.

13bf2618ef storage: improve PutBatch for MemoryStore
Make it look more like a real transaction, put/delete things with a single
lock. Make a copy of value in Put also, just for safety purposes, no one knows
how this value slice can be used after the Put.

e111892653 storage: redo DB testing
Make generic tests for all Store implementations, deduplicate tests. Implement
Delete() tests, test Seek() better, add LevelDB tests (finally!).

48b6a427cf storage: add Delete method for Batch and Store
It's gonna be used by Storage and Contract interops, both can delete their
data.

add9368e9d storage: use strings as keys for memory batch
Using pointers is just plain wrong here, because the batch can be updated with
newer values for the same keys.

Fixes Seek() to use HasPrefix also because this is the intended behavior.

7779ad6c28 storage: always return ErrKeyNotFound when key is not found

af557cea19 storage: deduplicate BoltDBBatch/MemoryBatch
BoltDB doesn't have internal batching mechanism, thus we have a substitute for
it, but this substitute is absolutely identical to MemoryBatch, so it's better
to unify them and import ac5d2f94d3 fix into the
MemoryBatch.

4a732d97ac storage: add comments about errors from MemoryStore
It never returns errors for some operations and this knowledge can be used by
other code.

920d7c610c core: remove blockCache, use MemoryStore, redesign persist()
Commit 578ac414d4 was wrong in that it saved
only a part of the block, so depending on how you use blockchain, you may
still see that the block was not really processed properly. To really fix it
this commit introduces intermediate storage layer in form of memStore, which
actually is a MemoryStore that supports full Store API (thus easily fitting
into the existing code) and one extension that allows it to flush its data to
some other Store.

It also changes AddBlock() semantics in that it only accepts now successive
blocks, but when it does it guarantees that they're properly added into the
Blockchain and can be referred to in any way. Pending block queing is now
moved into the server (see 8c0c055ac657813fe3ed10257bce199e9527d5ed).

So the only thing done with persist() now is just a move from memStore to
Store which probably should've always been the case (notice also that
previously headers and some other metadata was written into the Store
bypassing caching/batching mechanism thus leading to some inefficiency).

ac5d2f94d3 storage: fix BoltDB batched Put()
It must copy both the value and the key because they can be reused for other
purposes between Put() and PutBatch(). This actually happens with values in
headers processing, leading to wrong data being written into the DB.

Extend the batch test to check for that.

5bf00db2c9 io: move BinReader/BinWriter there, redo Serializable with it
The logic here is that we'll have all binary encoding/decoding done via our io
package, which simplifies error handling. This functionality doesn't belong to
util, so it's moved.

This also expands BufBinWriter with Reset() method to fit the needs of core
package.

4395cea344 storage: fix reading overlapping hash blocks from the DB
In the unlikely event of overlapping hash block written to the DB we might end
up with wrong hash list. That happened to me for some reason when synching
with the testnet leading to the following keys with respective values:
  150000 -> 2000 hashes
  152000 -> 2000 hashes
  153999 -> 2000 hashes

Reading it hashes number 153999 and 154000 got the same values and the chain
couldn't sync correctly.
