Here's two patches.  The first fixes some of the section names in the
r6rs-ports.test file, and can be applied to master immediately.

The second patch is the tests.  I ported tests in the most naive way
possible: copy/pasting the custom-binary-input-port and
custom-binary-output-port tests and adjusting for the
custom-binary-input/output-port.  It's not ideal, a bit spaghetti'ish,
but maybe that's okay?  I'm not sure.

However, two are not working: one fails and one errors, with the
following:

FAIL: r6rs-ports.test: 8.2.13 Input/output ports: custom binary input/output port supports `port-position', not `set-port-position!' - arguments: (expected-value 42 actual-value #f)
ERROR: r6rs-ports.test: 8.2.13 Input/output ports: custom binary input/output port unbuffered & 'port-position' - arguments: ((misc-error "seek" "port is not seekable" (#<input-output: file 10c0620>) #f))

I'm not sure if this is an error on my side, features not supported by
the new ports, or legitimate test failures.

I'll try to do more research, but if someone who's more knowledgable
knows what's going on, maybe that would speed things up.
