Damien George b56caaf104 travis: Build NUCLEO_L073RZ instead of B_L072Z_LRWAN1 for stm32 job.
The NUCLEO_L073RZ build is slightly bigger and this MCU has only 192k flash
so this helps to catch flash overflow.

Damien George 83461e37d4 stm32/boards: Disable pend_throw, uheapq, utimeq on small-flash boards.
These are mainly used by the previous version of uasyncio which is now
replaced by a newer version, with built-in C module _uasyncio.  Saves about
1300 bytes of flash.

David Lechner 6c77d5c7cd travis: Use grep with --text on qemu-arm output.
If the .out file contains non-text characters, grep won't show the output
unless we ask nicely.

David Lechner 0608fbff29 travis: Use custom PPA to get pre-built uncrustify.
Use PPA so that we don't have to rebuild uncrustify from source, speeding
up the job.  This also requires not running this test on arm64.

David Lechner 9418611c8a unix: Implement PEP 475 to retry syscalls failing with EINTR.
https://www.python.org/dev/peps/pep-0475/

This implements something similar to PEP 475 on the unix port, and for the
VfsPosix class.

There are a few differences from the CPython implementation:
- Since we call mp_handle_pending() between any ENITR's, additional
  functions could be called if MICROPY_ENABLE_SCHEDULER is enabled, not
  just signal handlers.
- CPython only handles signal on the main thread, so other threads will
  raise InterruptedError instead of retrying.  On MicroPython,
  mp_handle_pending() will currently raise exceptions on any thread.

A new macro MP_HAL_RETRY_SYSCALL is introduced to reduce duplicated code
and ensure that all instances behave the same.  This will also allow other
ports that use POSIX-like system calls (and use, eg, VfsPosix) to provide
their own implementation if needed.

David Lechner 5e6cee07ab unix/mpthreadport: Fix crash when thread stack size <= 8k.
The stack size adjustment for detecting stack overflow in threads was not
taking into account that the requested stack size could be <= 8k, in which
case the subtraction would overflow.  This is fixed in this commit by
ensuring that the adjustment can't be more than the available size.

This fixes the test tests/thread/thread_stacksize1.py which sometimes
crashes with a segmentation fault because of an uncaught NLR jump, which is
a "maximum recursion depth exceeded" exception.

Damien George bc009fdd62 extmod/uasyncio: Add optional implementation of core uasyncio in C.
Implements Task and TaskQueue classes in C, using a pairing-heap data
structure.  Using this reduces RAM use of each Task, and improves overall
performance of the uasyncio scheduler.

Damien George 38904b8937 tests/multi_net: Add uasyncio test for TCP server and client.
Includes a test where the (non uasyncio) client does a RST on the

uasyncio, and a test for TCP stream close then write.

Damien George 63b9944382 extmod/uasyncio: Add new implementation of uasyncio module.
This commit adds a completely new implementation of the uasyncio module.
The aim of this version (compared to the original one in micropython-lib)
is to be more compatible with CPython's asyncio module, so that one can
more easily write code that runs under both MicroPython and CPython (and
reuse CPython asyncio libraries, follow CPython asyncio tutorials, etc).
Async code is not easy to write and any knowledge users already have from
CPython asyncio should transfer to uasyncio without effort, and vice versa.

The implementation here attempts to provide good compatibility with
CPython's asyncio while still being "micro" enough to run where MicroPython
runs. This follows the general philosophy of MicroPython itself, to make it
feel like Python.

The main change is to use a Task object for each coroutine.  This allows
more flexibility to queue tasks in various places, eg the main run loop,
tasks waiting on events, locks or other tasks.  It no longer requires
pre-allocating a fixed queue size for the main run loop.

A pairing heap is used to queue Tasks.

It's currently implemented in pure Python, separated into components with
lazy importing for optional components.  In the future parts of this
implementation can be moved to C to improve speed and reduce memory usage.
But the aim is to maintain a pure-Python version as a reference version.

This fixes a bug in the pairing-heap implementation when nodes are deleted
with mp_pairheap_delete and then reinserted later on.

Damien George f8fc78691d py/mpconfig.h: Enable MICROPY_MODULE_GETATTR by default.
To enable lazy loading of submodules (among other things), which is very

Zoltán Vörös c5cc64175b ports: Add lib/libm/roundf.c to bare-metal Makefile's.
This function is not used by the core but having it as part of the build
allows it to be used by user C modules, or board extensions.  The linker
won't include it in the final firmware if it remains unused.

Andreas Motl fbfea3b440 drivers/onewire: Fix undefined variable errors.
On CPython, and with pylint, the variables MATCH_ROM and SEARCH_ROM are
undefined.  This code works in MicroPython because these variables are
constants and the MicroPython parser/compiler optimises them out.  But it
is not valid Python because they are technically undefined within the scope
they are used.

This commit makes the code valid Python code.  The const part is removed
completely because these constants are part of the public API and so cannot
be moved to the global scope (where they could still use the MicroPython
const optimisation).

David Lechner 3b07736b6d unix,windows: Use STDIN_FILENO, STDOUT_FILENO macros where appropriate.
This replaces 0 and 1 with STDIN_FILENO and STDOUT_FILENO to make the
intention of the code clearer.

David Lechner 100012bec6 windows: Remove custom definition of MP_PLAT_PRINT_STRN.
This removes the port-specific definition of MP_PLAT_PRINT_STRN on the
windows port, so that the default mp_hal_stdout_tx_strn_cooked() is always
used.  This fixes releasing the GIL during the call to write() (this was
missed in bc3499f010).

Also, mp_hal_dupterm_tx_strn() was defined but never used anywhere so it is
safe to delete it.

David Lechner b1066a9f96 unix: Remove custom definition of MP_PLAT_PRINT_STRN.
This removes the port-specific definition of MP_PLAT_PRINT_STRN on the unix
port.  Since fee7e5617f this is no longer a
single function call so we are not really optimising anything over using
the default definition of MP_PLAT_PRINT_STRN which calls
mp_hal_stdout_tx_strn_cooked().

Maureen Helm 76a5b3a97a zephyr: Update machine.Pin class to use new zephyr gpio api.
Zephyr v2.2 reworked its gpio api to support linux device tree bindings and
pin logical levels.  This commit updates the zephyr port's machine.Pin
class to replace the deprecated gpio api calls with the new supported gpio
api.  This resolves several build warnings.

Tested on frdm_k64f and mimxrt1050_evk boards.

Damien George 40255aff23 stm32/mboot: Remove unnecessary test for led being 1 in led_state.
The "led" argument is always a pointer to the GPIO port, or'd with the pin
that the LED is on, so testing that it is "1" is unnecessary.  The type of
"led" is also changed to uint32_t so it can properly hold a 32-bit pointer.

Andrew Leech 9dd470b768 stm32/mboot: Update LED0 state from systick handler.
Updating the LED0 state from systick handler ensures LED0 is always
consistent with its flash rate regardless of other processing going on in
either interrupts or main.  This improves the visible stability of the
bootloader, rather than LED0 flashing somewhat randomly at times.

This commit also changes the LED0 flash rate depending on the current state
of DFU, giving slightly more visual feedback on what the device is doing.
