Merge pull request #928 from tannewt/fix_uart_timeout
Correct UART reads to return error on timeout.

Scott Shawcroft ee817a2fa8 Correct UART reads to return error on timeout.
This causes read to correctly return None instead of b''.

Fixes #874

Damien George 035906419d extmod/uos_dupterm: Use native C stream methods on dupterm object.
This patch changes dupterm to call the native C stream methods on the
connected stream objects, instead of calling the Python readinto/write
methods.  This is much more efficient for native stream objects like UART
and webrepl and doesn't require allocating a special dupterm array.

This change is a minor breaking change from the user's perspective because
dupterm no longer accepts pure user stream objects to duplicate on.  But
with the recent addition of uio.IOBase it is possible to still create such
classes just by inheriting from uio.IOBase, for example:

    import uio, uos

    class MyStream(uio.IOBase):
        def write(self, buf):
            # existing write implementation
        def readinto(self, buf):
            # existing readinto implementation

Damien George 565f590586 ports: Enable IOBase on unix, stm32, esp8266 and esp32.

Damien George af0932a779 py/modio: Add uio.IOBase class to allow to define user streams.
A user class derived from IOBase and implementing readinto/write/ioctl can
now be used anywhere a native stream object is accepted.

The mapping from C to Python is:

    stream_p->read  --> readinto(buf)
    stream_p->write --> write(buf)
    stream_p->ioctl --> ioctl(request, arg)

Among other things it allows the user to:

- create an object which can be passed as the file argument to print:
  print(..., file=myobj), and then print will pass all the data to the
  object via the objects write method (same as CPython)
- pass a user object to uio.BufferedWriter to buffer the writes (same as
- use on a user object
- register user objects with select.poll, in particular so user objects can
  be used with uasyncio
- create user files that can be returned from user filesystems, and import
  can import scripts from these user files

For example:

    class MyOut(io.IOBase):
        def write(self, buf):
            print('write', repr(buf))
            return len(buf)

    print('hello', file=MyOut())

The feature is enabled via MICROPY_PY_IO_IOBASE which is disabled by

2018-06-12 11:56:25 +10:00
Damien George 522ea80f06 py/gc: Add gc_sweep_all() function to run all remaining finalisers.
This patch adds the gc_sweep_all() function which does a garbage collection
without tracing any root pointers, so frees all the memory, and most
importantly runs any remaining finalisers.

This helps primarily for soft reset: it will close any open files, any open
sockets, and help to get the system back to a clean state upon soft reset.

Scott Shawcroft 2fbab8067a Prevent freezing USB during high frequency PulseIn.
We now track the last time the background task ran and bail on the
PulseIn if it starves the background work. In practice, this
happens after the numbers from pulsein are no longer accurate.

This also adjusts interrupt priorities so most are the lowest level
except for the tick and USB interrupts.

Fixes #516 and #876
