__need_FOPEN_MAX wasn't being used anywhere. __need_IOV_MAX was more complicated; the basic deal is that sys/uio.h wants to define a constant named UIO_MAXIOV and bits/xopen_lim.h wants to define a constant named IOV_MAX, with the same meaning. For no apparent reason this was being handled via bits/stdio_lim.h -- stdio.h is NOT supposed to define IOV_MAX -- and some mess in Makerules. Also, bits/uio.h on Linux was being used as a dumping ground for extension functions. So now we have bits/uio_lim.h, which defines __IOV_MAX. bits/xopen_lim.h and sys/uio.h use that to define their respective constants. We also now have bits/uio-ext.h, which is the official Proper Home for extensions to sys/uio.h. bits/uio.h is removed, and stdio_lim.h doesn't define IOV_MAX at all. * bits/uio_lim.h, sysdeps/unix/sysv/linux/bits/uio_lim.h * bits/uio-ext.h, sysdeps/unix/sysv/linux/bits/uio-ext.h: New file. * bits/uio.h, sysdeps/unix/sysv/linux/bits/uio.h: Delete file. * include/bits/xopen_lim.h: Use bits/uio_lim.h to get the value for IOV_MAX. * misc/Makefile: Install bits/uio-ext.h and bits/uio_lim.h. Don't install bits/uio.h. * misc/sys/uio.h: Don't include bits/uio.h. Do include bits/types/struct_iovec.h and bits/uio_lim.h. Set UIO_MAXIOV based on __IOV_MAX. Under __USE_GNU, also include bits/uio-ext.h. * stdio-common/stdio_lim.h.in: Remove logic for __need_FOPEN_MAX and __need_IOV_MAX. Don't define IOV_MAX at all. * Makerules (stdio_lim.h): Remove logic for setting IOV_MAX. * sysdeps/unix/sysv/linux/bits/fcntl-linux.h: Include bits/types/struct_iovec.h, not bits/uio.h. Use __ssize_t, not ssize_t, in function prototypes. Don't use hard TAB for double space after period in comments.
