This commit adds size to the register_net_sysctl indirection function to facilitate the removal of the sentinel elements (last empty markers) from the ctl_table arrays. Though we don't actually remove any sentinels in this commit, register_net_sysctl* now has the capability of forwarding table_size for when that happens. We create a new function register_net_sysctl_sz with an extra size argument. A macro replaces the existing register_net_sysctl. The size in the macro is SIZE_MAX instead of ARRAY_SIZE to avoid compilation errors while we systematically migrate to register_net_sysctl_sz. Will change to ARRAY_SIZE in subsequent commits. Care is taken to add table_size to the stopping criteria in such a way that when we remove the empty sentinel element, it will continue stopping in the last element of the ctl_table array.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
