/**
Internal helper for implementing xVtab and xCursor.
The first argument must be the logical name of the
handler ('xVtab' or 'xCursor') and the second must be
the capi.XYZ struct-type value, e.g. capi.sqlite3_vtab
or capi.sqlite3_vtab_cursor.
A factory function which implements a simple lifetime manager for
mappings between C struct pointers and their JS-level wrappers.
The first argument must be the logical name of the manager
(e.g. 'xVtab' or 'xCursor'), which is only used for error
reporting. The second must be the capi.XYZ struct-type value,
e.g. capi.sqlite3_vtab or capi.sqlite3_vtab_cursor.
Returns an object with 4 methods: create(), get(), unget(), and
dispose(), plus a StructType member with the value of the 2nd
argument. The methods are documented in the body of this
function.
