2b4d05a575 Revert 'Maintain order of property enumeration by keeping a linked list.' 
Reduce memory use per property by not keeping the properties in two
parallel data structures. Maintaining the order of insertion is not
required by the spec, and is not a very useful feature.

3e3c382a0c Avoid using 'unsigned int'. 
Mixing signed and unsigned ints is just a plain headache.

c90c32326e Fix bugs introduced when moving from argc to js_gettop. 
The 'length' field of a function is used to fill in missing arguments
with undefined; this does not mesh well with functions that query for
missing arguments using js_gettop. Set their lengths to 0 instead.

031513b25b Add stack traces to error objects. 
Revert 'add context and flag argument to js_newstate' commit.

The context argument just adds clutter. The flag which was intended
for JS_DEBUG and/or JS_STRICT shouldn't be necessary.

js_newcfunction and js_newcconstructor need an extra argument, the
name of the function to use in stack traces.

5dbd120154 Fix several constructors. 
"is/was supplied/specified" is different from "is not undefined" which
is used in most of the spec.

70b0d8b902 Change C functions to not have a return value. 
They should always push a return value on the JS stack.

90b54a9eec Add userdata class. 
js_newuserdata(J, tag, ptr) creates a userdata object, wrapping the ptr.
It takes the prototype for the new object from the top of the stack, just
like js_newcconstructor does.

js_touserdata(J, tag, idx) extracts the userdata pointer. Throws a
TypeError if the object is not a userdata object with a matching tag.

js_isuserdata(J, tag, idx) checks if a value on the stack is a userdata
object with a matching tag.

b262cc3673 Rename many jsR functions to jsV. 
Danger! jsV work on values internally without the stack.

Also rearrange how C-constructors are created.

81b2bb9ca4 Add constructors called with 'new' keyword. 
Support built-in constructors that create their own objects. They get
called without a this object, which they should create and push on the
stack.
