This system call was never visible to user space, so it makes
sense to move it out of the main table of system calls into
the notes below the table.

Reduce the chance that the reader may be misled into thinking
that there is a wrapper function for this system call by noting
explicitly in the SYNOPSIS that there is no glibc wrapper and
pointing the reader to NOTES for further details.

Improve the example demonstrating allocation of a buffer
for readdir_r() to handle -1 error return from pathconf().
Otherwise, naive readers may think that pathconf() return
value can be used without checking.

Add text to NOTES to say that the <sys/types.h> and <sys/ipc.h>
header files aren't required by Linux or the standards, but may
be needed for portability to old systems.

Including <sys/types.h> and <sys/ipc.h> isn't needed on Linux
and isn't really relevant for the explanation on this page.

There's no need to mention that the 'ipc_perm' structure
is defined in <sys/ipc.h>. That's an implementation detail,
and furthermore <sys/ipc.h> is itself included by the other
System V IPC header files. The current text might lead the
reader to conclude that they must include <sys/ipc.h>, which
is not the case (it is required neither on Linux, nor by the
standards).
