What?
These commits set things up so we can start removing the sentinel elements.
They modify sysctl and net_sysctl internals so that registering a ctl_table
that contains a sentinel gives the same result as passing a table_size
calculated from the ctl_table array without a sentinel. We accomplish this by
introducing a table_size argument in the same place where procname is checked
for NULL. The idea is for it to keep stopping when it hits ->procname == NULL,
while the sentinel is still present. And when the sentinel is removed, it will
stop on the table_size (thx to jani.nikula@linux.intel.com for the discussion
that led to this). This allows us to remove sentinels from one (or several)
files at a time.

These commits are part of a bigger set containing the removal of ctl_table sentinel
(https://github.com/Joelgranados/linux/tree/tag/sysctl_remove_empty_elem_V3).
The idea is to make the review process easier by chunking the 65+ commits into
manageable pieces.

Thanks, I've dropped the old set and merged this updated one onto sysctl-next.
