177cab5fe7 trie: ensure resolved nodes stay loaded
Commit 40cdcf1183 broke the optimisation which kept nodes resolved
during Get in the trie. The decoder assigned cache generation 0
unconditionally, causing resolved nodes to get flushed on Commit.

This commit fixes it and adds two tests.

187d6a66a5 trie: avoid loading the root node twice
New checks whether the root node is present by loading it from the
database. Keep the node around instead of discarding it.

40cdcf1183 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

c3a77d6268 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.

b8ca0a830e 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.
