We want to be able to capture StateUpdates even if the Geth snapshot
trie is in a weird state and can't offer the snapshot we're looking
for. This adds our own implementation of the Snapshot() interface
so that we can continue collecting the necessary information to make
it available to the StateUpdates hook.

The loop variable changes before the defer executes, so we need to
pass it to the function to make sure the closure has the correct
version of the loop variable.
It turns out we were only notifying plugins of freezer commits and
cleaning up our record when the block being processed was greater
than MAX_UINT64.
So, uh, never.
While looking for the source of a memory leak, I decided to optimize
the metatracer to avoid encoding values when there weren't any tracers
configured to received the encoded values.
I also avoided putting the EVM into debug mode when there weren't any
tracers configured.
None of these fixed the memory leak, but they still seem like good
practices. Memory leak fix is in the next commit.
* core/vm: reverse bit order in bytes of code bitmap
This bit order is more natural for bit manipulation operations and we
can eliminate some small number of CPU instructions.
* core/vm: drop lookup table
This PR reduces the amount of work we do when answering header queries, e.g. when a peer
is syncing from us.
For some items, e.g block bodies, when we read the rlp-data from database, we plug it
directly into the response package. We didn't do that for headers, but instead read
headers-rlp, decode to types.Header, and re-encode to rlp. This PR changes that to keep it
in RLP-form as much as possible. When a node is syncing from us, it typically requests 192
contiguous headers. On master it has the following effect:
- For headers not in ancient: 2 db lookups. One for translating hash->number (even though
the request is by number), and another for reading by hash (this latter one is sometimes
cached).
- For headers in ancient: 1 file lookup/syscall for translating hash->number (even though
the request is by number), and another for reading the header itself. After this, it
also performes a hashing of the header, to ensure that the hash is what it expected. In
this PR, I instead move the logic for "give me a sequence of blocks" into the lower
layers, where the database can determine how and what to read from leveldb and/or
ancients.
There are basically four types of requests; three of them are improved this way. The
fourth, by hash going backwards, is more tricky to optimize. However, since we know that
the gap is 0, we can look up by the parentHash, and stlil shave off all the number->hash
lookups.
The gapped collection can be optimized similarly, as a follow-up, at least in three out of
four cases.

This PR fixes a special corner case in transaction indexing.
When the chain is rewound by SetHead to a historical point which is even lower than the transaction indexes tail, then system will report Failed to decode block body error all the time, because the relevant blocks are already deleted.
In order to avoid this "non-critical-but-annoying" issue, we can recap the indexing target to head+1(to is excluded, so it means indexing transactions from 0 to head).
