Instead of using anonymous maps, define tagged struct types for JSON argument
encoding. This allows us to have the encoding rules we want without tmjson.

This commit handles the "easy" cases. BroadcastEvidence is omitted here,
because it depends on the interface encoding rules from tmjson. I will address
that in a forthcoming change.

Defines a different concrete type that satisfies the service interface for a seed node.
update the seed node unit test to assert the new type.

Fixes #6775

* Update Caller interface and its documentation.
* Rework MapToRequest as ParamsToRequest.

The old interface returned the result as well as populating it.  Nothing was
using this, so drop the duplicated value from the return signature. Clarify the
documentation on the Caller type.

Rework the MapToRequest helper to take an arbitrary value instead of only a
map. This is groundwork for getting rid of the custom marshaling code. For now,
however, the implementation preserves the existing behaviour for the map, until
we can replace those.

These two interfaces are identical, and besides HTTPClient being confusingly
named, all but one location uses Caller. Update that one location, and drop the
redundant interface.

Apart from the tests for the websocket client, positional parameters are not
used by RPC clients. The server supports both arrays and objects, but the
client only needs to provide one or the other.

Where possible, replace uses of the custom JSON library with the standard
library. The custom library treats interface and unnamed lteral types
differently, so this change avoids those even where it would probably be safe
to switch them.

These tests use a deterministic and unseeded random source to generate
non-colliding filenames for testing. When testing locally, this means tests are
not hermetic from one run to the next.

Use proper temp directories, and clean up after they're done.

The JSON-RPC endpoint accepts requests via URL (GET) and JSON (POST).  There is
no real point in having client libraries for both modes.

A search of the SDK and on GitHub suggests that most usage is via the JSON
client (via the New constructor) or websocket (NewWS), and the only uses I
found of the NewURI client constructor are in copies of our own test code.

This does not change the functionalitiy of the server, so curl and other
URL-based clients in other languages will still function as before.
