manual: add syscalls
The purpose of this patch is to add some system calls that (1) aren't
otherwise documented, and (2) are merely redirected to the kernel, so
can refer to their documentation; and define a standard way of doing
so in the future.  A more detailed explaination of how system calls
are wrapped is added along with reference to the Linux Man-Pages
project.

Default version of man-pages is in configure.ac but can be overridden
by --with-man-pages=X.Y
