rpc: improve error codes for internal server errors (#25678)
This changes the error code returned by the RPC server in certain situations:

- handler panic: code -32603
- result marshaling error: code -32603
- attempt to subscribe via HTTP: code -32001

In all of the above cases, the server previously returned the default error
code -32000.

rpc: add PeerInfo (#24255)
This replaces the sketchy and undocumented string context keys for HTTP requests
with a defined interface. Using string keys with context is discouraged because
they may clash with keys created by other packages.

We added these keys to make connection metadata available in the signer, so this
change also updates signer/core to use the new PeerInfo API.

rpc: add separate size limit for websocket (#22385)
This makes the WebSocket message size limit independent of the
limit used for HTTP requests. The new limit for WebSocket messages 
is 15MB.

internal/ethapi: return revert reason for eth_call (#21083)
* internal/ethapi: return revert reason for eth_call

* internal/ethapi: moved revert reason logic to doCall

* accounts/abi/bind/backends: added revert reason logic to simulated backend

* internal/ethapi: fixed linting error

* internal/ethapi: check if require reason can be unpacked

* internal/ethapi: better error logic

* internal/ethapi: simplify logic

* internal/ethapi: return vmError()

* internal/ethapi: move handling of revert out of docall

* graphql: removed revert logic until spec change

* rpc: internal/ethapi: added custom error types

* graphql: use returndata instead of return

Return() checks if there is an error. If an error is found, we return nil.
For most use cases it can be beneficial to return the output even if there
was an error. This code should be changed anyway once the spec supports
error reasons in graphql responses

* accounts/abi/bind/backends: added tests for revert reason

* internal/ethapi: add errorCode to revert error

* internal/ethapi: add errorCode of 3 to revertError

* internal/ethapi: unified estimateGasErrors, simplified logic

* internal/ethapi: unified handling of errors in DoEstimateGas

* rpc: print error data field

* accounts/abi/bind/backends: unify simulatedBackend and RPC

* internal/ethapi: added binary data to revertError data

* internal/ethapi: refactored unpacking logic into newRevertError

* accounts/abi/bind/backends: fix EstimateGas

* accounts, console, internal, rpc: minor error interface cleanups

* Revert "accounts, console, internal, rpc: minor error interface cleanups"

This reverts commit 2d3ef53c5304e429a04983210a417c1f4e0dafb7.

* re-apply the good parts of 2d3ef53c53

* rpc: add test for returning server error data from client

8008c5b1fa rpc: remove 'exported or builtin' restriction for parameters (#20332)
* rpc: remove 'exported or builtin' restriction for parameters

There is no technial reason for this restriction because package reflect
can create values of any type. Requiring parameters and return values to
be exported causes a lot of noise in package exports.

* rpc: fix staticcheck warnings

rpc: implement full bi-directional communication (#18471)
New APIs added:

    client.RegisterName(namespace, service) // makes service available to server
    client.Notify(ctx, method, args...)     // sends a notification
    ClientFromContext(ctx)                  // to get a client in handler method

This is essentially a rewrite of the server-side code. JSON-RPC
processing code is now the same on both server and client side. Many
minor issues were fixed in the process and there is a new test suite for
JSON-RPC spec compliance (and non-compliance in some cases).

List of behavior changes:

- Method handlers are now called with a per-request context instead of a
  per-connection context. The context is canceled right after the method
  returns.
- Subscription error channels are always closed when the connection
  ends. There is no need to also wait on the Notifier's Closed channel
  to detect whether the subscription has ended.
- Client now omits "params" instead of sending "params": null when there
  are no arguments to a call. The previous behavior was not compliant
  with the spec. The server still accepts "params": null.
- Floating point numbers are allowed as "id". The spec doesn't allow
  them, but we handle request "id" as json.RawMessage and guarantee that
  the same number will be sent back.
- Logging is improved significantly. There is now a message at DEBUG
  level for each RPC call served.
