Round out SYSCTL macros to the full set of fixed-width types

Add S8, S16, S32, and U32 types; add SYSCTL*() macros for them, as well
as for the existing 64-bit types. (While SYSCTL*QUAD and UQUAD macros
already exist, they do not take the same sort of 'val' parameter that
the other macros do.)

Clean up the documented "types" in the sysctl.9 document. (These are
macros and thus not real types, but the manual page documents intent.)

The sysctl_add_oid(9) arg2 has been bumped from intptr_t to intmax_t to
accommodate 64-bit types on 32-bit pointer architectures.

This is just the kernel support piece; the userspace sysctl(1) support
will follow in a later patch.

sysctl(9): Document U8/U16 types from r289773

Suggested by: ngie
Sponsored by: EMC / Isilon Storage Division

Teach sysctl about the new optional suffix after IK to specify
precision. Update input as well. Add IK to the manual (it was missing
completely).

Differential Revision: https://reviews.freebsd.org/D3181

Fix multiple incorrect SYSCTL arguments in the kernel:

- Wrong integer type was specified.

- Wrong or missing "access" specifier. The "access" specifier
sometimes included the SYSCTL type, which it should not, except for
procedural SYSCTL nodes.

- Logical OR where binary OR was expected.

- Properly assert the "access" argument passed to all SYSCTL macros,
using the CTASSERT macro. This applies to both static- and dynamically
created SYSCTLs.

- Properly assert the the data type for both static and dynamic
SYSCTLs. In the case of static SYSCTLs we only assert that the data
pointed to by the SYSCTL data pointer has the correct size, hence
there is no easy way to assert types in the C language outside a
C-function.

- Rewrote some code which doesn't pass a constant "access" specifier
when creating dynamic SYSCTL nodes, which is now a requirement.

- Updated "EXAMPLES" section in SYSCTL manual page.

- Updated SYSCTL manual pages after recent changes to the kernel
SYSCTL code. Added description of new macros and functions.
- Merged dynamic and static SYSCTL related content into a single
manual page, hence parameters and functionality is very much the same.
- Uppercased all occurrences of "OID".
- Updated all SYSCTL examples.

PR: 192101

- Document the UQUAD sysctl variants.
- Clarify that exactly one of the "access" flags is required and
list the optional flags in a separate list. Prefer bundling
CTLFLAG_TUN into the access flag by not documenting it as an
optional flag to set.

Correct the description for CTLFLAG_TUN and CTLFLAG_RDTUN, the declaring of a
system tunable has never been implemented. This flag is only used by sysctl(8)
to provide a helpful error message.

Discussed with: dwhite, kan

Introduce signed and unsigned version of CTLTYPE_QUAD, renaming
existing uses. Rename sysctl_handle_quad() to sysctl_handle_64().

sysctl(8) should use the CTLTYPE to determine the type of data when
reading. (This was already done for writing to a sysctl). This
requires all SYSCTL setups to specify a type. Most of them are now
checked at compile-time.

Remove SYSCTL_*X* sysctl additions as the print being in hex should be
controlled by the -x flag to sysctl(8).

Xref sysctl(3)

Approved by: ed (mentor)

Implement the following macros for completeness:

SYSCTL_QUAD()
SYSCTL_ADD_QUAD()
TUNABLE_QUAD()
TUNABLE_QUAD_FETCH()

Now we can use 64bit tunables on 32bit systems.

Spelling fixes.

Add a guideline for naming new sysctl nodes.

Revise markup.

Add an extension to the UINT & ULONG types. The XINT & XLONG types behave

Add a basic man page for the sysctl(9) macro interfaces. Previously man
pages existed only for the dynamic sysctl interfaces. There's probably
more complete and accurate content, better advice, etc, that could be added
here.

Per scottl's suggest, add a small piece of moralizing text regarding the
fact that sysctl names quickly get embedded in system configuration files,
libraries, third party applications, and even books, so renaming and
removing names after they've been published is a tricky issue.
