[Rd] R-devel now uses lazy loading

The R-devel version of R now uses lazy loading, in which objects in a 
package are initially stored in a database and replaced by a promise.  
This makes R much faster to start up (40% of the previous time) and it 
will (usually) use a smaller footprint.

Given the loss of the CVS archive whilst I was away the merging has had to 
be done manually and so a lot of checking of a CVS branch has been lost.
You will almost certainly need to do make clean if updating an existing 

Packages can be installed to use lazy loading by INSTALL --lazy.  This is 
not yet the default, but it will become so in due course, so please test 
your package(s) with lazy loading before submission to CRAN.
