* Convert a value from the given index into the lua stack to an nvpair, adding

*
* Values are converted as follows:
*
* string -> string
* number -> int64
* boolean -> boolean
* nil -> boolean (no value)
*
* Lua tables are converted to nvlists and then inserted. The table's keys
* are converted to strings then used as keys in the nvlist to store each table
* element. Keys are converted as follows:
*
* string -> no change
* number -> "%lld"
* boolean -> "true" | "false"
* nil -> error
*
* In the case of a key collision, an error is thrown.
*
* If an error is encountered, a nonzero error code is returned, and an error
* string will be pushed onto the Lua stack.
