dev/portal: fix bug in portal callback forwarding
...
When forwarding rx/tx callback from the underlaying device(pipe), the
"dev" argument should be the portal. So the portal callback could think
itself as called.

dev/portal: add checks on oflag
...
It does not make sense to open portal without a flag. One should open a
portal with RT_DEVICE_OFLAG_RDWR in most cases.

dev/portal: implement portal device
...
Portal is a device that connect devices. Currently, you can only connect
pipes in portal. Pipes are unidirectional. But with portal, you can
construct a bidirectional device with two pipes.

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.

ringbuffer: add put_force and putchar_force API

ringbuffer: fix the ambiguous name
...
RT_RINGBUFFER_SIZE could mean "the size of the whole buffer", "the size
of the empty space" or "the size of the data". Moreover, it's never a
micro anymore. Change it to rt_ringbuffer_data_len before it's too late.
Also, RT_RINGBUFFER_EMPTY is changed to rt_ringbuffer_space_len.

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.

reimplement ringbuffer
...
The new implementation use the mirroring method to distinguish full
buffer and the empty buffer. It also support buffers of arbitrary size.
