* configure.ac: Remove AC_FUNC_SETVBUF_REVERSED.

This macro is obsolete: no useful system has this problem anymore.
* src/output.c (output_init): Remove reference to SETVBUF_REVERSED.
* src/config.ami.template: Remove undef of SETVBUF_REVERSED.
* src/config.h-vms.template: Ditto.
* src/config.h.W32.template: Ditto.
