written code, and it doesn't work or even compile yet. I am committing
it to make it easier to discuss the approach with jelmer and tpot.

The intention is that this code will eventually end up being mostly
auto-generated (with the utility functions split out, just like
librpc/ndr/*.c)

I hope that this code will eventually be autogenerated.
In this code, the convention is:
ejs_pull_*() from MprVar -> C structure
ejs_push_*() from C structure -> MprVar
note that for ejs calls, pull only ever needs to do
NDR_IN, and push only ever needs to do NDR_OUT. This is
because ejs code is (at least for the moment) only used for
the client, not the server
also note that we don't need the NDR_SCALARS/NDR_BUFFERS stuff, as
we aren't dealing with wire marshalling where scalars and buffers
are separated
