Implements undo command and optional timeout for configuration
Several new configure command variants:
configure undo - undo last reconfigurationconfigure timeout - configure with scheduled undo if not confirmed in timeoutconfigure confirm - confirm last configuration...
Split CF_HDR section to CF_HDR (only includes) and CF_DEFINES (defines,C declarations etc.).
Command line interface now works.
Parse CLI commands. We use the same parser as for configuration files (becausewe want to allow filter and similar complex constructs to be used in commandsand we should avoid code duplication), only with CLI_MARKER token prependedbefore the whole input....
Fixed bug in CF_ADDTO. How it's possible it has ever worked?
This script takes configuration fragments and generates full Bison grammarfrom them.
