This adds the ability to stream `tar` archives over channels between
`wsh` instances. The main use cases for this are remote copy and move
operations.
It also completes the `wavefs` implementation of the FileShare interface
to allow copy/move interoperability between wavefiles and other storage
types.
The tar streaming functionality has been broken out into the new
`tarcopy` package for easy reuse.
New `fileshare` functions are added for `CopyInternal`, which allows
copying files internal to a filesystem to bypass the expensive interop
layer, and `MoveInternal`, which does the same for moving a file within
a filesystem. Copying between remotes is now handled by `CopyRemote`,
which accepts the source `FileShareClient` as a parameter. `wsh`
connections use the same implementation for `CopyInternal` and
`CopyRemote` as they need to request the channel on the remote
destination, since we don't offer a way to pass channels as a parameter
to a remote call.
This also adds a recursive `-r` flag to `wsh file rm` to allow for
deleting a directory and all its contents.
S3 support will be addressed in a future PR.

This adds an RPC command for updating wsh on a remote machine without
starting a new session. It is not being used yet, but will be used for
connections using a single server in the future.
Fixes

To fix the problem, we need to ensure that the size computation for the
allocation does not overflow. This can be achieved by validating the
length of `barr` before performing the arithmetic operation. We will set
a maximum allowable size for `barr` to ensure that the sum of
`oscPrefixLen(oscNum)` and `len(barr)` does not exceed the maximum value
for an `int`.
1. Define a maximum allowable size for `barr` (e.g., 64 MB).
2. Check the length of `barr` against this maximum size before
performing the allocation.
3. If `barr` exceeds the maximum size, return an error.

This makes it possible to send wsh commands from wsh on a remote session
to wavesrv running locally. The exact behavior of running those commands
isn't implemented, but the underlying interface is added here.
lots of changes. new wshrpc implementation. unify websocket, web,
blockcontroller, domain sockets, and terminal inputs to all use the new
rpc system.
lots of moving files around to deal with circular dependencies
use new wshrpc as a client in wsh cmd
