After the MPSAFE TTY import, we have support for the TAB0 and TAB3 flags to handle tab expansion, while we only used to support OXTABS. Switch stty(1) to use tab0 and tab3 to print whether tab expansion is turned on or off. Implement the oxtabs and tabs switches by setting the appropriate TABx value. Even though POSIX only lists this as being XSI, we'd better follow it.
