  sys_uio: new module
  
  For now, just provide the types used by sys/socket.  We could
  add readv() and writev() later, if desired.
  
  * modules/sys_uio: New module.
  * modules/sys_uio-tests: Likewise.
  * lib/sys_uio.in.h: New file.
  * m4/sys_uio_h.m4: Likewise.
  * tests/test-sys_uio.c: Likewise.
  * doc/posix-headers/sys_uio.texi (sys/uio.h): Document it.
  * MODULES.html.sh (systems lacking POSIX:2008): Likewise.
