Add support for serializing to, and de-serializing from, JSON, as
specified in RFC 8259. Format is automatically detected for input,
and can be specified explicitly for output. The default format remains
XML.

As part of this change, generic prop_object_{internalize,externalize}()
functions are provided, and the "_with_format" flavor allows the output
format to be specified. Previous array- and dictionary-specific routines
remain for backwards compatibility.

Fix commas in NAME section.

Add the *_size() variants to the .Nm list so it will be found by
apropos(1).

While here, reorder the function lists to improve readability.

Use just the right amount of commas.

Update for the new *_size() functions recently added. Mention the
implicit size limit (128KB) for the functions which do not take an
explicit limit argument.

Add commas in enumerations.

- Implement prop_{array,dictionary}_copyout(), based on
prop_{array,dictionary}_copyout_ioctl().
- Implement prop_{array,dictionary}_recv_syscall(), which
takes as parameter the pref we got from kernel and internalize it,
and unmaps the buffer prop_{array,dictionary}_copyout() mapped for us.
- add a prop_{array,dictionary}_send_syscall() for symetry, which is
an alias to prop_{array,dictionary}_externalize_to_pref()

Discussed on tech-kern@ and tech-userlevel@
