In the past week I've added a lot of additional options for a PVA link,
which I think brings it close to feature complete (for a first version anyway).

An example, with all of the defaults made explicit is:

> record(longin, "tgt") {}
> record(longin, "src") {
>     field(INP, {pva:{
>         pv:"tgt",
>         field:"",
>         local:false,
>         Q:4,
>         pipeline:false,
>         proc:none,
>         sevr:false,
>         time:false,
>         monorder:0,
>         retry:false,
>         always:false,
>         defer:false
>     }})
> }

I've tried to describe all of these on the documentation page, although
it would be nice to get some comments as to how well I've succeeded.

I've also added a demo/test IOC which I'll be expanding to cover as many
of the options, and combinations of options, as I can think of.

If/when someone looks at this, please take some notes about anything
which confuses.  I have a particular interest in finding out what
could be added to facilitate troubleshooting.
