Changed 'guid' to 'pid' to be in line with the D1 API.

simplify the MN rest servlet mapping to match CN mappings - also streamlined the handler code to share extra path info parsing

add space to error message

route all /d1/cn/* traffic through the CNRestServlet/Handler -- inspect the pathInfo when deciding what action to take and also strip off any extra parts (like pid).
include query() method pass-through to CNodeService

add the old ecogrid query code (still commented out) from the old Rest handler

allow service implementation method to throw exception when guid parameter is null

allow parameters to be omitted in reserveIdentifier handling

implement reserveIdentifier() and check whether the id is reserved when creating records (only allow the create when the Subject creating matches the Subject who reserved it -- currently stored in rightsHolder)

allow for provisional SystemMetadata records (provisional=true)

remove extraneous update() call when create() does the call for us
