Implement a read-only mode for libxl__datacopier.

Read-only in the sense that it only reads, or in the sense that one may
only read from it?

It only reads rather than reading and writing.


What is the purpose of this mode?

Where does the data go?


This mode allows data from an fd to be read into memory using libxl's async framework. The data goes into the user-allocated libxl__datacopier_state.readbuf.
