mainly done in order to judge the complexity of the EIP
and to act as a jumping off point, since the eip will likely
change.

Currently geth ignores the docker `--memory` directive and doesn't
adjust its cache size downward when necessary, potentially running into
OOM.
while gopsutil has functions like `docker/CgroupMem()` they are rather
for reading cgroup memory limit of a container from the host.
This PR adds an optimization to the `findNodeByID` function in
`p2p/discover`. There is already an open PR (#33205) for similar
improvements, and I have further optimized the function to get better
performance. I have attached the benchmark results comparing the current
`main` branch with my `optimized version`, and the results show clear
improvements.

This PR introduces a cache for GetBlobs request.
The main purpose of this PR is to reduce the getBlobs latency by reading and
decoding blobs from the pool in advance of the actual query. This is important
especially in the context of a sparse blobpool, since it may be necessary to
recover blobs from cells on a getBlobs request.
Previously, the Engine API read and decoded blobs from the pool on every call.
Now those calls check the cache and only fall back to the pool on a miss.
The cache has two modes:
- In topK mode (default), it wakes up periodically, picks the most profitable
pending blob transactions up to the current fork's maxBlobsPerBlock, and loads
their blobs. The selection logic is shared with the miner's block-building
logic. The selection size is derived from eip4844.MaxBlobsPerBlock at the
current head.
- When the CL calls HasBlobs, the cache switches to hasBlobs mode and tries to
pin the set it just reported as available. Cache updates (read, decode, and
optionally conversion in the future) run in background goroutines.

Adds snap/2 (EIP-8189), a block-access-list (BAL) based state sync, and
wires it to run side by side with snap/1. It's opt-in (for now) behind a
new --snap.v2 flag and chosen at startup.

In old code, mu is struct not pointer, it caused create new mutex event
with same writer. Change to use pointer to sync.Mutex, so that the mutex
is shared between handler with same writer.
This adds a client option to configure trace context propagation via the
`traceparent` HTTP header.
I'm adding this so that prysm can enable distributed tracing on their
engine API client.
This is a PR that removes all correctly flagged typos, in order to stop
an onslaught of slop PRs in its tracks. It should be followed by #34994
but the latter needs more configuration work and I want to limit the
stem of PRs right now.
Fixes an issue where we would falsely return 400 when we should return
200 because the request was served successfully

This PR is trying to stem further slop PRs by going over all incorrect
strings and fixing them.
