This version adds support for command line editing and history using the libedit or readline libraries in addition to the line editing features available in previous versions. The version in the base system is configured to use libedit. This allows to choose between emacs and vi line editing commands and to use command overrides via a ~/.editrc file. Merge commit 'bd54318046bfee055b140705a5cfd4148e78da07' PR: 264010 MFC after: 2 weeks
