Prototype async REPL using IPython, take III
This is a squash and a rebase of a large number of commits from Min and
I. For simplicity of managing it, history has been reduced to a single
commit, but more historical versions can be found, in particular in
PR 11155, or commit
aedb5d6d3a441dcdb7180ac9b5cc03f91329117b to be more
exact.
