'pipe' now takes an optional 'flags' parameter.

Browse source 
This is the same strategy as used for the 'accept4' bindings introduced
in 6e0965104c.

* libguile/posix.c (scm_pipe): Rename to...
(scm_pipe2): ... this.  Add an optional 'flags' parameter and honor it.
(scm_pipe): Rewrite as a call to 'scm_pipe2'.
* libguile/posix.h (scm_pipe2): New declaration.
* test-suite/tests/posix.test ("pipe"): New tests.
* configure.ac: Look for 'pipe2'.
* NEWS: Update.
