MFC 4cd1807c7d2a67b633dd0c0bfde15091543a2514:

Retire the K&R/STD C __P prototype declarations.

In the old days when K&R C and STD C were each in use a workaround
(read hack) was required to allow the same code to work on each
without modification. All C compilers support STD C. We can finally
put the __P prototype to rest.

ipfilter: Retire pre-standard C support.

All C compilers in 2021 support standard C and architectures that did
not were retired long ago. Simplify by removing now redundant
pre-standard C code.

MFC r315368:

calloc() and realloc() modernization.

This commit replaces calloc calls, which called calloc() as if it were
malloc() by allocating a multiple of objects as a sizeof multiplied by
the number of objects. The patch rectifies this by calling calloc() as
it was meant to be called.

This commit also replaces realloc() with reallocarray() in a similar
fashion as above. Instead of calculating the memory to reallocated
(changed) by multiplying sizeof by the number of objects, the sizeof
and number are passed as separate arguments to reallocarray(), letting
reallocarray() do the multiplication instead. Like the calloc()
adjustment above, this is approach is cleaner and more elegant than
than the previous code.

This has been tested on my production firewall and a laptop (also
running ipfilter).

Resolve conflicts (and believe me...you don't want to know).

* Someone imported a lot of files with the wrong CVS tag, so lots of files need
that fixed in them....
* Keep unnecessary files out of the non-vendor part of this CVS repository.
