Remove miscellaneous debris from libio.
This patch eliminates a number of #if 0 and #ifdef TODO blocks, macros that are never used, macros that provide portability to substrates that lack basic things like EINVAL and off_t, and other such debris. I preserved IO_DEBUG and CHECK_FILE, even though as far as I can tell IO_DEBUG is never defined and therefore CHECK_FILE never does anything, because it seems like we might actually want to turn it _on_. Installed stripped libraries and executables are unchanged, except, again, that the line number of an assertion changes (this time it's somewhere in fileops.c). * libio/libio.h (_IO_pos_BAD, _IO_pos_0, _IO_pos_adjust): Define here, unconditionally. * libio/iolibio.h (_IO_pos_BAD): Don't define here. * libio/libioP.h: Remove #if 0 blocks. (_IO_pos_BAD, _IO_pos_0, _IO_pos_adjust): Don't define here. (_IO_va_start, COERCE_FILE, MAYBE_SET_EINVAL): Don't define. (CHECK_FILE): Don't use MAYBE_SET_EINVAL or COERCE_FILE. Fix style. * libio/clearerr.c, libio/fputc.c, libio/getchar.c: Assume weak_alias is always defined. * libio/fileops.c, libio/genops.c, libio/oldfileops.c * libio/oldpclose.c, libio/pclose.c, libio/wfileops.c: Remove #if 0 and #ifdef TODO blocks. Assume text_set_element is always defined. * libio/iofdopen.c, libio/iogetdelim.c, libio/oldiofdopen.c Use __set_errno (EINVAL) instead of MAYBE_SET_EINVAL. * libio/tst-mmap-eofsync.c: Make #if 1 block unconditional.
