dev/pipe: make pipe a type of device
...
Pipe have many differences with char device. The main difference is
altough pipe have both read and write, it is unidirectional in nature.

dev/pipe: call rx_indicate the time we resume reader
...
Some reader(FinSh again) would like to block on a semaphore which is
released in rx_indicate. So we should invoke rx_indicate in
_rt_pipe_resume_reader.

device/pipe: add nonblocking read/write and force write mode
...
The previous implementation will always blocks the reader/writer.
However, at least FinSh would expect the device to be nonblocking ---
read should return 0 when there is no data in it.

device/pipe: add rt_pipe_{init,detach}
...
This provide the possibility that allocate the buffer of the ringbuffer
on a specific region, instead of always mallocing it. It also bring us
the benefit of using pipe device on the systems without heap.
