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.

core/bloombits: remove micro-sleep

This PR introduces a new mechanism in chain tracer for preventing creating too many trace states.

The workflow of chain tracer can be divided into several parts:

- state creator generates trace state in a thread
- state tracer retrieves the trace state and applies the tracing on top in another thread
- state collector gathers all result from state tracer and stream to users

It's basically a producer-consumer model here, while if we imagine that the state producer generates states too fast, then it will lead to accumulate lots of unused states in memory. Even worse, in path-based state scheme it will only keep the latest 128 states in memory, and the newly generated state will invalidate the oldest one by marking it as stale.

The solution for fixing it is to limit the speed of state generation. If there are over 128 states un-consumed in memory, then the creation will be paused until the states are be consumed properly.

Backwards compatibility warning: The result will from now on omit empty fields instead
of including a zero value (e.g. no more `balance: '0x'`).

The prestateTracer will now take an option `diffMode: bool`. In this mode
the tracer will output the pre state and post data for the modified parts of state.
Read-only accesses will be completely omitted. Creations (be it account or slot)
will be signified by omission in the `pre` list and inclusion in `post`. Whereas
deletion (be it account or slot) will be signified by inclusion in `pre` and omission
in `post` list.

This PR makes it so that the snap server responds to trie heal requests when possible, even if the snapshot does not exist. The idea being that it might prolong the lifetime of a state root, so we don't have to pivot quite as often.

add a testcase to TestLegacyReceiptDecoding

This PR makes it possible to set custom headers, in particular for two scenarios: 

- geth attach
- geth commands which can use --remotedb, e..g geth db inspect

The ability to use custom headers is typically useful for connecting to cloud-apis, e.g. providing an infura- or alchemy key, or for that matter access-keys for environments behind cloudflare.

This fixes a cornercase bug where the flag migration would mess
up the value of StringSlice flags.

* accounts/abi/bind: parse ABI once on bind

* accounts/abi/bind: suppress 'imported and not used' error for abi package

* eth/tracers: add revertReason to callTracer

* update callframe gen json

* add revertal to calltrace test

This PR reworks tx indexer a bit. Compared to the original version, one scenario is no longer handled - upgrading  from legacy geth without indexer support. 

The tx indexer was introduced in 2020 and have been present through hardforks, so it can be assumed that all Geth nodes have tx indexer already. So we can simplify the tx indexer logic a bit:

-    If the tail flag is not present, it means node is just initialized may or may not with an ancient store attached. In this case all blocks are regarded as unindexed
-   If the tail flag is present, it means blocks below tail are unindexed, blocks above tail are indexed

This change also address some weird cornercases that could make the indexer not work after a crash.

This change adds zero-padding (prefix) of odd nibbles in the decodeHash function.

This PR prevent making tiny writes during state healing, by only performing the batch-write if the accumulated data is large enough to be meaningful.

This fixes a bug where contract code would be overridden to empty code ("0x")
when the Code field of OverrideAccount was left nil. The change also cleans up
the encoding of overrides to only send necessary fields, and improves documentation.

Fixes #25615

The call tracer and prestate tracer store data JSON-encoded in memory. In order to support alternative encodings (specifically RLP), it's better to keep data a native format during tracing. This PR does marshalling at the end, using gencodec.

OBS! 
This PR changes the call tracer result slightly:

-  Order of type and value fields are changed (should not matter). 
-  Output fields are completely omitted when they're empty (no more output: "0x"). Previously, this was only _sometimes_ omitted (e.g. when call ended in a non-revert error) and otherwise 0x when the output was actually empty. 

Some tests define an 'expectException' error but the tests runner does not check for conditions where this test value is filled (error expected) but in which no error is returned by the test runner.

An example of this scenario is GeneralStateTests/stTransactionTest/HighGasPrice.json, which expects a 'TR_NoFunds' error, but the test runner does not return any error.

`geth dumpgenesis` currently does not respect the content of the data directory. Instead, it outputs the genesis block created by command-line flags. This PR fixes it to read the genesis from the database, if the database already exists.
