  Log:
  Add kernel syscall support for explicit blocking and non-blocking I/O
  regardless of the setting applied to the file pointer.
  
  send/sendmsg/sendto/recv/recvmsg/recfrom: New MSG_ flags defined in
  sys/socket.h may be passed to these functions to override the settings
  applied to the file pointer on a per-I/O basis.
  
  MSG_FBLOCKING	- Force the operation to be blocking
  MSG_FNONBLOCKING- Force the operation to be non-blocking
  
  pread/preadv/pwrite/pwritev: These system calls have been renamed and
  wrappers will be added to libc.  The new system calls are prefixed with
  a double underscore (like getcwd vs __getcwd) and include an additional
  flags argument.  The new flags are defined in sys/fcntl.h and may be
  used to override settings applied to the file pointer on a per-I/O basis.
  
  Additionally, the internal __ versions of these functions now accept an
  offset of -1 to mean 'degenerate into a read/readv/write/writev' (i.e.
  use the offset in the file pointer and update it on completion).
  
  O_FBLOCKING	- Force the operation to be blocking
  O_FNONBLOCKING	- Force the operation to be non-blocking
  O_FAPPEND	- Force the write operation to append (to a regular file)
  O_FOFFSET	- (implied of the offset != -1) - offset is valid
  O_FSYNCWRITE	- Force a synchronous write
  O_FASYNCWRITE	- Force an asynchronous write
  O_FUNBUFFERED	- Force an unbuffered operation (O_DIRECT)
  O_FBUFFERED	- Force a buffered operation (negate O_DIRECT)
  
  If the flags do not specify an operation (e.g. neither FBLOCKING or
  FNONBLOCKING are set), then the settings in the file pointer are used.
  
  The original system calls will become wrappers in libc, without the flags
  arguments.  The new system calls will be made available to libc_r to allow
  it to perform non-blocking I/O without having to mess with a descriptor's
  file flags.
  
  NOTE: the new __pread and __pwrite system calls are backwards compatible
  with the originals due to a pad byte that libc always set to 0.
  The new __preadv and __pwritev system calls are NOT backwards compatible,
  but since they were added to HEAD just two months ago I have decided
  to not renumber them either.
  
  NOTE: The subrev has been bumped to 1.5.4 and installworld will refuse to
  install if you are not running at least a 1.5.4 kernel.
