This capability is required for read pipelining. We will only read in as
many records as will fit in the read buffer (and the network can provide
in one go). The bigger the buffer the more records we can process in
parallel.

For config targets such as 'dist', which doesn't have a BASE template,
we still need to have a default build scheme.

Additionally, the unified Makefile template's target 'tar' wasn't
quite as flexible as the unixmake one.

Finally, .travis-create-release.sh can be somewhat simplified now that
it builds with the unified build scheme.

Because of the unified scheme, building on different platforms is very
similar.  We currently have Unix and OpenVMS on the unified scheme,
which means that a separate INSTALL.VMS is no longer needed.

Previously s_client and s_server relied on using SSL_pending() which does
