[issue12196] add pipe2() to the os module

[Charles-François Natali]

New submission from Charles-François Natali <neologix at free.fr>:

pipe2() makes it possible to create a pipe O_CLOEXEC or O_NONBLOCK atomically, which can be quite useful, especially in multi-threaded code. It would be nice to expose it in the os module.
Patch attached.
