[R] test version of RODBC

[ripley@stats.ox.ac.uk]

I've recently done a lot of re-writing of the internals of RODBC, and have
a test version 0.99-6 available.  This is a run-up to the release of 1.0.
Both the source code and a Windows binary (prepared under rw1062) are
available at http:/www.stats.ox.ac.uk/pub/R, and I would appreciate some
real users testing this version.

It should be more efficient as data frames are transferred to and from the
DBMS in binary format (rather via character matrices) where possible.  
Also missing values as database nulls now work on Access and should work
everywhere.  For Windows users there are more general (and interactive)
ways to open ODBC connections.  And so on ... see the ChangeLog.

The main remaining task before RODBC-1.0 is to rationalize the handling of 
error conditions, and to build on David James' work and add a DBI 
interface layer (as an alternative).
