stijn 40ad8f1666 all: Rename "sys" module to "usys".
This is consistent with the other 'micro' modules and allows implementing
additional features in Python via e.g. micropython-lib's sys.

Note this is a breaking change (not backwards compatible) for ports which
do not enable weak links, as "import sys" must now be replaced with
"import usys".

Andrew Leech a80a146858 extmod/bluetooth: Support active scanning in BLE.gap_scan().
This adds an additional optional parameter to gap_scan() to select active
scanning, where scan responses are returned as well as normal scan results.
This parameter is False by default which retains the existing behaviour.

Damien George 2acc087880 extmod/vfs_lfs: Add mtime support to littlefs files.
This commit adds support for modification time of files on littlefs v2
filesystems, using file attributes.  For some background see issue #6114.

Features/properties of this implementation:
- Only supported on littlefs2 (not littlefs1).
- Uses littlefs2's general file attributes to store the timestamp.
- The timestamp is 64-bits and stores nanoseconds since 1970/1/1 (if the
  range to the year 2554 is not enough then additional bits can be added to
  this timestamp by adding another file attribute).
- mtime is enabled by default but can be disabled in the constructor, eg:
  uos.mount(uos.VfsLfs2(bdev, mtime=False), '/flash')
- It's fully backwards compatible, existing littlefs2 filesystems will work
  without reformatting and timestamps will be added transparently to
  existing files (once they are opened for writing).
- Files without timestamps will open correctly, and stat will just return 0
  for their timestamp.
- mtime can be disabled or enabled each mount time and timestamps will only
  be updated if mtime is enabled (otherwise they will be untouched).

Zenix27 e76c7466b6 docs: Change `\*` to `*` in argument lists.
Latest versions of Sphinx (at least 3.1.0) do not need the `*` escaped and
will render the `\` in the output if it is there, so remove it.

Jon Rob 1678f41744 esp32/esp32_rmt: Extend RMT to support carrier feature.
The ESP32 RMT peripheral has hardware support for a carrier frequency, and
this commit exposes it to Python with the keyword arguments carrier_freq
and carrier_duty_percent in the constructor.  Example usage:

    r = esp32.RMT(0, pin=Pin(2), clock_div=80, carrier_freq=38000, carrier_duty_percent=50)

  use :noindex:
- 2 cases where `` should have been used instead of `

Damien George 3b6c9119eb extmod/modbluetooth: Add support for changing the GAP device name.
This commit allows the user to set/get the GAP device name used by service
0x1800, characteristic 0x2a00.  The usage is:

    BLE.config(gap_name="myname")
    print(BLE.config("gap_name"))

As part of this change the compile-time setting
MICROPY_PY_BLUETOOTH_DEFAULT_NAME is renamed to
MICROPY_PY_BLUETOOTH_DEFAULT_GAP_NAME to emphasise its link to GAP and this
new "gap_name" config value.  And the default value of this for the NimBLE
bindings is changed from "PYBD" to "MPY NIMBLE" to be more generic.

Thorsten von Eicken 952ff8a8ea esp32: Improve support for OTA updates.
This commit adds several small items to improve the support for OTA
updates on an esp32:

- a partition table for 4MB flash modules that has two OTA partitions ready
  to go to do updates
- a GENERIC_OTA board that uses that partition table and that enables
  automatic roll-back in the bootloader
- a new esp32.Partition.mark_app_valid_cancel_rollback() class-method to
  signal that the boot is successful and should not be rolled back at the
  next reset
- an automated test for doing an OTA update
- documentation updates

Jim Mussared 7563d58210 unix: Add support for modbluetooth and BLE using btstack.

Thorsten von Eicken a177831c46 esp32/modesp32: Add idf_heap_info(capabilities) to esp32 module.
This commit adds an idf_heap_info(capabilities) method to the esp32 module
which returns info about the ESP-IDF heaps.  It's useful to get a bit of a
picture of what's going on when code fails because ESP-IDF can't allocate
memory anymore.  Includes documentation and a test.

make it possible to write code that is compatible with CPython.

Andrew Leech 86bfabec11 py/modmicropython: Add heap_locked function to test state of heap.
This commit adds micropython.heap_locked() which returns the current
lock-depth of the heap, and can be used by Python code to check if the heap
is locked or not.  This new function is configured via
MICROPY_PY_MICROPYTHON_HEAP_LOCKED and is disabled by default.

This commit also changes the return value of micropython.heap_unlock() so
it returns the current lock-depth as well.

Damien George dd0bc26e65 extmod/modbluetooth: Change scan result's "connectable" to "adv_type".
This commit changes the BLE _IRQ_SCAN_RESULT data from:

    addr_type, addr, connectable, rssi, adv_data

to:

    addr_type, addr, adv_type, rssi, adv_data

This allows _IRQ_SCAN_RESULT to handle all scan result types (not just
connectable and non-connectable passive scans), and to distinguish between
them using adv_type which is an integer taking values 0x00-0x04 per the BT
specification.

This is a breaking change to the API, albeit a very minor one: the existing
connectable value was a boolean and True now becomes 0x00, False becomes
0x02.

Documentation is updated and a test added.

Fixes #5738.

Peter Hinch 88cbfd791a docs/library: Fix framebuf monochrome 1-bit modes, swapping HLSB/HMSB.
This fix can be demonstrated by the following:

    b = bytearray(32)
    f = framebuf.FrameBuffer(b, 32, 8, framebuf.MONO_HLSB)
    f.pixel(0, 0, 1)
    print('MONO_HLSB', hex(b[0]))

    b = bytearray(32)
    f = framebuf.FrameBuffer(b, 32, 8, framebuf.MONO_HMSB)
    f.pixel(0, 0, 1)
    print('MONO_HMSB', hex(b[0]))

Outcome:

    MONO_HLSB 0x80
    MONO_HMSB 0x1

Damien George 84958a8fe1 extmod/modbluetooth: Allow setting ringbuf size via BLE.config(rxbuf=).
The size of the event ringbuf was previously fixed to compile-time config
value, but it's necessary to sometimes increase this for applications that
have large characteristic buffers to read, or many events at once.

With this commit the size can be set via BLE.config(rxbuf=512), for
example.  This also resizes the internal event data buffer which sets the
maximum size of incoming data passed to the event handler.

Damien George 7aeafe2ae9 extmod/modbluetooth: Add optional 4th arg to gattc_write for write mode.
This allows the user to explicitly select the behaviour of the write to the
remote peripheral.  This is needed for peripherals that have
characteristics with WRITE_NO_RESPONSE set (instead of normal WRITE).  The
function's signature is now:

    BLE.gattc_write(conn_handle, value_handle, data, mode=0)

mode=0 means write without response, while mode=1 means write with
response.  The latter was the original behaviour so this commit is a change
in behaviour of this method, and one should specify 1 as the 4th argument
to get back the old behaviour.

In the future there could be more modes supported, such as long writes.
