Issue 6877: this patch makes it possible to link the readline extension
to the libedit emulation of the readline API on OSX 10.5 or later. This also adds a minimal testsuite for readline to check that the history manipuation functions have the same interface with both C libraries.

+Very minimal unittests for parts of the readline module.
+
+These tests were added to check that the libedit emulation on OSX and
+the "real" readline have the same interface for history manipulation. That's
+why the tests cover only a small subset of the interface.
