Don't force the 'HAL' string to be part of the platform string because
it doesn't have a sensible meaning for all possible platforms, and
swap it with the PLATFORM_ARCH string so the strings which most platforms
have come first.
We're using the MicroPython fork of NimBLE, which on the
`micropython_1_4_0` branch re-adds support for 64-bit targets and fixes
initialisation of g_msys_pool_list.
Also updates modbluetooth_nimble.c to suit v1.4.

To simplify the socket state.
The CC3K driver (see drivers/cc3000/inc/socket.h and src/socket.c) has
socket() returning an INT16 so there is now enough room to store it
directly in the fileno member.
The network.STA_IF and network.AP_IF constants are now independent to the
CYW43_ITF_STA and CYW43_ITF_AP constants.

This commit refactors machine.PWM and creates extmod/machine_pwm.c. The
esp8266, esp32 and rp2 ports all use this and provide implementations of
the required PWM functionality. This helps to reduce code duplication and
keep the same Python API across ports.
This commit does not make any functional changes.

The zephyr port doesn't support SoftI2C so it's not enabled, and the legacy
I2C constructor check can be removed.

Otherwise the Python network object continues to report that it is
attempting to connect.
Also make the return error code consistent with wifi scan.

This achieves a substantial performance improvement when rendering glyphs
to color displays, the benefit increasing proportional to the number of
pixels in the glyph.
This is a generic API for synchronously bit-banging data on a pin.
Initially this adds a single supported encoding, which supports controlling
WS2812 LEDs.

This allows the write to trigger a notification or indication, but only to
subscribed clients. This is different to gatts_notify/gatts_indicate,
which will unconditionally notify/indicate.

The correct callback-deregister functions must be called dependent on the
socket type, otherwise resources may not be freed correctly.

Optionally enabled via MICROPY_PY_UJSON_SEPARATORS. Enabled by default.
For dump, make sure mp_get_stream_raise is called after
mod_ujson_separators since CPython does it in this order (if both
separators and stream are invalid, separators will raise an exception
first).
Add separators argument in the docs as well.

When l2cap_send detects that the sys mempool is running low (used to store
the outgoing HCI payloads), it will report stalled back to the application,
and then only unstall once these HCI payloads have been sent.
This prevents a situation where a remote receiver with very large MTU can
cause NimBLE to queue up more than MYNEWT_VAL_MSYS_1_BLOCK_COUNT (i.e. 12)
payloads, causing further attempts to send to fail with ENOMEM (even though
the channel is not stalled and we have room in the channel mbufs). The
regular credit/stall flow control is not effective here because the
receiver's MTU is large enough that it will not activate (i.e. there are
lots of credits available).
Thresholds of 1/2 (stall) and 1/4 (unstall) chosen to allow headroom for
other payloads (e.g. notifications) and that when a regular stall occurs it
might keep sending (and creating more payloads) in the background.
In 2ae3c890bd, -Wimplicit-fallthrough=0 was
added to get the build to pass. This option is equivalent to
-Wno-implicit-fallthrough, and the latter is compatible with clang (while
the former is not).
Fixes issue #7546.

A correctly-behaved application shouldn't do this, but in the
case where the channel is stalled, there's still enough room
in the mbuf pool, then we'll fail the send (BLE_HS_EBUSY) so
the mbuf needs to be freed.

This adds #if MICROPY_PY_USELECT_SELECT around the uselect.select()
function. According to the docs, this function is only for CPython
compatibility and should not normally be used. So we can disable it
and save a few bytes of flash space where possible.
