Work on an alternate (slightly simpler) approach to binding JS vtabs. Non-eponymous vtabs are not working, for reasons as yet unknown.

/**
Constructs this object with a message depending on its arguments:
- If it's passed only a single integer argument, it is assumed
to be an sqlite3 C API result code. The message becomes the
result of sqlite3.capi.sqlite3_js_rc_str() or (if that returns
falsy) a synthesized string which contains that integer.
If its first argument is an integer, it is assumed to be
an SQLITE_... result code and it is passed to
sqlite3.capi.sqlite3_js_rc_str() to stringify it.
- If passed 2 arguments and the 2nd is a object, it behaves
like the Error(string,object) constructor except that the first
argument is subject to the is-integer semantics from the
previous point.
If called with exactly 2 arguments and the 2nd is an object,
that object is treated as the 2nd argument to the parent
constructor.
- Else all arguments are concatenated with a space between each
one, using args.join(' '), to create the error message.
The exception's message is created by concatenating its
arguments with a space between each, except for the
two-args-with-an-objec form and that the first argument will
get coerced to a string, as described above, if it's an
integer.
If passed an integer first argument, the error object's
`resultCode` member will be set to the given integer value,
else it will be set to capi.SQLITE_ERROR.
