trie, core/state: improve memory usage and performance ( #3135 )
...
* trie: store nodes as pointers
This avoids memory copies when unwrapping node interface values.

* trie: close temporary databases in GetDB benchmark
* trie: don't keep []byte from DB load around
Nodes decoded from a DB load kept hashes and values as sub-slices of
the DB value. This can be a problem because loading from leveldb often
returns []byte with a cap that's larger than necessary, increasing
memory usage.
* trie: unload old cached nodes
* trie, core/state: use cache unloading for account trie
* trie: use explicit private flags (fixes Go 1.5 reflection issue).
* trie: fixup cachegen overflow at request of nick
* core/state: rename journal size constant

trie: fix delete bug for values contained in fullNode
...
Delete crashed if a fullNode contained a valueNode directly. This bug is
very unlikely to occur with SecureTrie, but can happen with regular
tries. This commit also introduces a randomised test which triggers all
trie operations, which should prevent such bugs in the future.
Credit for finding this bug goes to Github user @rjl493456442.

eth, trie: removed key prefixing from state entries & merge db fix
...
Fixed database merge strategy to use the correct database. Due to a copy
paste fail when doing type evaluation the same database was being
iterated (chain), all others were ignored.
Removed state prefixing because {H(code): code} is stored in the same
database as the rest of the state.
