[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 build.

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.
