eth/filters, core/rawdb: remove unused param, refactor filtering-loop (#27891)
This change removes a chainconfig parameter passed into rawdb.ReadLogs, which is not used nor needed.
It also modifies the filter loop slightly, avoiding a labeled break and instead using a method.

This change does not modify any behaviour.

miner: suspend miner if node is syncing (#27218)
Drop the notions of uncles, and disables activities while syncing

-  Disable activities (e.g. generate pending state) while node is syncing,
-  Disable empty block submission (but empty block is still kept for payload building),
-  Drop uncle notion since (ethash is already deprecated)

eth/filters: retrieve logs in async (#27135)
This change implements async log retrievals via feeding logs in channels, instead of returning slices. This is a first step to implement #15063.

rpc: change BlockNumber constant values to match ethclient (#27219)
ethclient accepts certain negative block number values as specifiers for the "pending",
"safe" and "finalized" block. In case of "pending", the value accepted by ethclient (-1)
did not match rpc.PendingBlockNumber (-2).

This wasn't really a problem, but other values accepted by ethclient did match the
definitions in package rpc, and it's weird to have this one special case where they don't.

To fix it, we decided to change the values of the constants rather than changing ethclient.
The constant values are not otherwise significant. This is a breaking API change, but we
believe not a dangerous one.

eth/filters: avoid block body retrieval when no matching logs (#25199)
Logs stored on disk have minimal information. Contextual information such as block
number, index of log in block, index of transaction in block are filled in upon request.
We can fill in all these fields only having the block header and list of receipts.
But determining the transaction hash of a log requires the block body.

The goal of this PR is postponing this retrieval until we are sure we the transaction hash.
It happens often that the header bloom filter signals there might be matches in a block,
but after actually checking them reveals the logs do not match. We want to avoid fetching
the body in this case.

Note that this changes the semantics of Backend.GetLogs. Downstream callers of
GetLogs now assume log context fields have not been derived, and need to call
DeriveFields on the logs if necessary.

eth/filters: fix for eth_getLogs failing with finalized- and safe tag (#25922)
Prior to this change, f.begin (and possibly end) stay negative, leading to strange results later in the code. With this change, filters using "safe" and "finalized" block produce results consistent w/ the overall behavior of this RPC method.

ca376ead88 les, light: LES/2 protocol version (#14970)
This PR implements the new LES protocol version extensions:

* new and more efficient Merkle proofs reply format (when replying to
  a multiple Merkle proofs request, we just send a single set of trie
  nodes containing all necessary nodes)
* BBT (BloomBitsTrie) works similarly to the existing CHT and contains
  the bloombits search data to speed up log searches
* GetTxStatusMsg returns the inclusion position or the
  pending/queued/unknown state of a transaction referenced by hash
* an optional signature of new block data (number/hash/td) can be
  included in AnnounceMsg to provide an option for "very light
  clients" (mobile/embedded devices) to skip expensive Ethash check
  and accept multiple signatures of somewhat trusted servers (still a
  lot better than trusting a single server completely and retrieving
  everything through RPC). The new client mode is not implemented in
  this PR, just the protocol extension.

2ab2a9f131 core/bloombits, eth/filters: handle null topics (#15195)
When implementing the new bloombits based filter, I've accidentally broke null
topics by removing the special casing of common.Hash{} filter rules, which
acted as the wildcard topic until now.

This PR fixes the regression, but instead of using the magic hash
common.Hash{} as the null wildcard, the PR reworks the code to handle nil
topics during parsing, converting a JSON null into nil []common.Hash topic.

c213fd1fd8 all: import "context" instead of "golang.org/x/net/context"
There is no need to depend on the old context package now that the
minimum Go version is 1.7. The move to "context" eliminates our weird
vendoring setup. Some vendored code still uses golang.org/x/net/context
and it is now vendored in the normal way.

This change triggered new vet checks around context.WithTimeout which
didn't fire with golang.org/x/net/context.

7731061903 core/vm: move Log to core/types
This significantly reduces the dependency closure of ethclient, which no
longer depends on core/vm as of this change.

All uses of vm.Logs are replaced by []*types.Log. NewLog is gone too,
the constructor simply returned a literal.

1fe67c125d eth/filters: add FindOnce for iterator-like operation (#3435)
This commit introduces a FindOnce method for filters. FindOnce finds the next block that
matches the filter and returns all matching logs from that block. If there are no further
matching logs, it returns a nil slice. This method allows callers to iterate over large
sets of logs progressively.

The changes introduce a small inefficiency relating to mipmaps: the first time a filter is
called, it acts as if all mipmaps are matched, and thus iterates several blocks near the
requested start point. This is in the interest of simplicity and avoiding duplicate mipmap
lookups each time FindOnce is called.

f52a1ae849 core, core/vm, eth/filters: move Removed field into vm.Log
This field used to be assigned by the filter system and returned through
the RPC API. Now that we have a Go client that uses the underlying type,
the field needs to move. It is now assigned to true when the RemovedLogs
event is generated so the filter system doesn't need to care about the
field at all.

While here, remove the log list from ChainSideEvent. There are no users
of this field right now and any potential users could subscribe to
RemovedLogsEvent instead.

Pending logs are now filterable through the Go API. Filter API changed
such that each filter type has it's own bucket and adding filter
explicitly requires you specify the bucket to put it in.

Out of Bound log events are events that were removed due to a fork. When
logs are received the filtering mechanism should check for the `removed`

6dc14788a2 core, eth/filters, miner, xeth: Optimised log filtering
Log filtering is now using a MIPmap like approach where addresses of
logs are added to a mapped bloom bin. The current levels for the MIP are
in ranges of 1.000.000, 500.000, 100.000, 50.000, 1.000. Logs are
therefor filtered in batches of 1.000.
