Avoid global in p2p macro (fixes #4578) (#5719)
* Avoid global in p2p macro (fixes #4578)

* copy p2p macro to this repo and start de-crufting it
* make protocol registration dynamic, removing light client hacks et al
* split out light client protocol into its own file

* cleanups

* Option -> Opt
* remove more cruft

* further split beacon_sync

this allows the light client to respond to peer metadata messages
without exposing the block sync protocol

* better protocol init

* "constant" protocol index

* avoid casts

* copyright

* move some discovery code to discovery

* avoid extraneous data copy when sending chunks

* remove redundant forkdigest field

* document how to connect to a specific peer

reduce redundant zero initialization for LC data objects (#5479)
Directly initialize `ForkedLightClientObj` instead of separately first
 setting the `kind` (initializing everything to zero) and then assigning
the forky data after that.

add `libnimbus_lc.a` C library (#5122)
Add a new C library for processing light client data based on the Nimbus
implementation. This can be used from other, non-Nimbus components.

broaden `SszError` catches to `SerializationError` (#5081)
`nim-serialization` is tagged with `{.raises:[SerializationError].}` so
it is no longer sufficient to catch `SszError` in some situations.
`SszError` inherits from `SerializationError`, so broadening the caught
exception types can be done now, to enable bumping `nim-serialization`.

https://github.com/status-im/nimbus-eth2/pull/5043#issuecomment-1584227993

#5061 is also needed to bump `nim-serialization`.

split SSZ and JSON parsing logic in LC handler (#5055)
Use separate functions per format when parsing LC data from REST.
This allows to process events from the eventstream more directly,
as they are always JSON not SSZ. And also makes the code cleaner.

move spec constants to spec (#4825)
* move spec constants to spec

quite funny, this removes >_1000_ transitive imports when building
`nimbus_validator_client`.

`genDepend`:

```sh
[arnetheduck@praeceps beacon_chain]$ diff -u
nimbus_validator_client.dot.pre nimbus_validator_client.dot | wc
   1167    3507  103822
```

* imports

* better constants

* oops

* too many blobs

* reorder spec constants in fork order

* cleanup

allow trusted node sync based on LC trusted block root (#4736)
* allow trusted node sync based on LC trusted block root

Extends `trustedNodeSync` with a new `--trusted-block-root` option that
allows initializing a light client. No `--state-id` must be provided.
The beacon node will then use this light client to obtain the latest
finalized state from the remote server in a trust-minimized fashion.
Note that the provided `--trusted-block-root` should be somewhat recent,
and that security precautions such as comparing the state root against
block explorers is still recommended.

* fix

* workaround for `valueOr` limitations

* reduce magic numbers

* digest len > context len for readability

* move `cstring` conversion to caller

* avoid abbreviations

* `return` codestyle
