@MatrixParam should not inherit values

[glassfishrobot]

Given: /images;offset=

{offset}

;count=

{count}/random;count={count}

Where /images is implemented using one resource, and /random using a sub-resource

If I declare @MatrixParam in the sub-resource random but the client does not
specify the "count" parameter at all, I should get null (indicating the
parameter was missing) instead of inheriting the value of count from /images.
Currently there is no obvious way to detect the real value of count for /random.

With respect to implementing the entire URL with a single Resource, it should be
possible to get:

1. The first, last value or some other convention, or
2. A list of all values, or
3. A mapping between path segments and the associated parameter values (similar
   to what we would get if we used a sub-resource)

Changing the current behavior would introduce a backwards incompatibility. We could consider adding a
new property to @MatrixParam to control inheritance but the default value would need to represent the
current behavior. A workaround is to use UriInfo.getPathSegments() in the method body.

Instead of adding a new property to @MatrixParam to control inheritance, leave the current method as-is and add a second method that returns #3 (a mapping between map segments and associated values). This will maintain backwards compatibility and allow us to test the approach in the Jersey namespace before promoting it to javax.ws.rs.

Marek, what do you think?
