enable wsh file cross-remote copy/move (#1725)

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.
