With this change no more preset aliases exist, so the preset alias tables can be safely removed. All ksh commands can now be used without 'unalias -a' removing them, even in interactive shells. Additionally, the history and r commands are no longer limited to being used in interactive shells. src/cmd/ksh93/bltins/hist.c: - Implement the history and r commands as builtins. Also guarantee lflag is set to one by avoiding 'lflag++'. src/cmd/ksh93/Makefile, src/cmd/ksh93/Mamfile, src/cmd/ksh93/sh/main.c, src/cmd/ksh93/sh/init.c, src/cmd/ksh93/data/aliases.c: - Remove the table of predefined aliases because the last few have been removed. During init the alias tree is now initialized the same way as the function tree. src/cmd/ksh93/bltins/typeset.c: - Remove the bugfix for unsetting predefined aliases because it is now a no-op. Aliases are no longer able to have the NV_NOFREE attribute. src/cmd/ksh93/tests/alias.sh: - Remove the regression test for unsetting predefined aliases since those no longer exist. src/cmd/ksh93/data/builtins.c: - Update sh_opthist[] for 'hist --man', etc. src/cmd/ksh93/sh.1: - Remove the list of preset aliases since those no longer exist. - Document history and r as builtins instead of preset aliases.
