db: Simplify exists check, fix IsKeyInDomain signature, Iterator Close 
+ *FSDB.HasKey now uses common.FileExists to test for file existence
+ IsKeyInDomain takes key as a []byte slice instead of as a string
to avoid extraneous []byte<-->string conversions for start and end
+ Iterator.Close() instead of Iterator.Release()
+ withDB helper to encapsulate DB creation, deferred cleanups
so that for loops can use opened DBs and discard them ASAP

Alexis Sellier e9e6ec3a2c Implement Key/Value on Iterator for GoLevelDB 
This is needed because leveldb reuses the keys on each iteration.
In our wrapper, we copy the key/value so that it is safe to store.

Alexis Sellier 296d223545 Add Release & Error methods to Iterator 
We need this to properly support LevelDB backend, which needs
to be released if we don't want to leak memory.

db: fix MemDB.Close 
Fixes https://github.com/tendermint/tmlibs/issues/55

MemDB previously mistakenly set the actual DB pointer to nil
although that side effect is not visible to the outside world
since p is an identifier within the scope of just that function
call. However, @melekes and I had a discussion in which we
came to the conclusion that Close for an in-memory DB should
instead be a noop and not cause any data loss. See the
discussion on https://github.com/tendermint/tmlibs/pull/56.
