* [#8985](https://github.com/apache/nuttx/pull/8985) drivers/pipe: make pipe and named pipe (mkfifo) POSIX-compliant (blocking open)  

It would be a possible breaking change if any application was written specifically to expect an open for write-only 
(and O_NONBLOCK cleared, of course) to be non-blocking even if there are no readers.
Being able to port POSIX-compliant applications that expect open to block when opening for write-only with no readers
would enhance NuttX's objective of "to achieve a high degree of standards compliance. The primary governing standards 
are POSIX and ANSI standards". That is the case for RTP Tools, for instance.
