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.

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.
* 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

* 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
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.
