8bc3fc20fe esp8266: Rename "machine" module implementation to use contemporary naming.
Previously they used historical "pyb" affix causing confusion and
inconsistency (there's no "pyb" module in modern ports; but people
took esp8266 port as an example, and "pyb" naming kept proliferating,
while other people complained that source structure is not clear).

6ab2c5e6cc lib/interrupt_char: Factor out typical Ctrl+C handling from esp8266 port.
Utility functions for keyboard interrupt handling, to be reused across
(baremetal) ports.

45f3416816 esp8266: Enable DHT C-level driver.
Exposed as esp.dht_readinto.  Probably should go somewhere less
port-specific.

4b37e775ea extmod/machine_i2c: Redo mp_hal_pin macros to use open_drain and od_low.
mp_hal_pin_config_od is renamed mp_hal_pin_open_drain, and mp_hal_pin_low
is mp_hal_pin_od_low.

67a6d31955 esp8266: Allow GPIO16 to be used as a pin in the uPy pin HAL.
Now I2C works with GPIO16 as the SCL or SDA pin.

a2d5d84ecc esp8266: Convert mp_hal_pin_obj_t from pin ptr to simple integer.
Most pin I/O can be done just knowing the pin number as a simple
integer, and it's more efficient this way (code size, speed) because it
doesn't require a memory lookup to get the pin id from the pin object.

If the full pin object is needed then it can be easily looked up in the
pin table.

d4f4cb6a24 esp8266/esp_mphal: Remove mp_hal_feed_watchdog.
It doesn't do anything and is not needed.  ets_loop_iter/ets_event_poll
now take care of feeding the WDT.

98af891610 esp8266: Implement input part of dupterm handling.
The idea is following: underlying interrupt-driven or push-style data source
signals that more data is available for dupterm processing via call to
mp_hal_signal_dupterm_input(). This triggers a task which pumps data between
actual dupterm object (which may perform additional processing on data from
low-level data source) and input ring buffer.

61fa7c8152 esp8266: Switch back to accumulating input data via ring buffer.
But now it's generic ring buffer implemented via ringbuf.h, and is intended
for any type of input, including dupterm's, not just UART. The general
process work like this: an interrupt-driven input source puts data into
input_buf, and then signals new data available via call to
mp_hal_signal_input().

9475cc59e6 esp8266: Support synchronous wifi scanning.
That is: aps = if0.scan()

TODO: make sure that returned list has tuple with values in "standard"
order (whatever that standard is).

402a743821 esp8266/esp_mphal: Add support for debug UART-only output.
Helpful when debugging dupterm support (because otherwise all output is
spooled to dupterm too).

To use:

mp_printf(&mp_debug_print, "...");

a4c8ef9d16 esp8266: Reset "virtual RTC" on power on.
Initialize RTC period coefficients, etc. if RTC RAM doesn't contain valid
values. time.time() then will return number of seconds since power-on, unless
set to different timebase.

This reuses MEM_MAGIC for the purpose beyond its initial purpose (but the whole
modpybrtc.c need to be eventually reworked completely anyway).

731f359292 all: Add py/mphal.h and use it in all ports.
py/mphal.h contains declarations for generic mp_hal_XXX functions, such
as stdio and delay/ticks, which ports should provide definitions for.  A
port will also provide mphalport.h with further HAL declarations.

2fc1e64319 esp8266: Fix lost chars problem when block-xfering data (e.g., when pasting).
Pasting more or less sizable text into ESP8266 REPL leads to random chars
missing in the received input. Apparent cause is that using RTOS messages
to pass individual chars one by one is to slow and leads to UART FIFO
overflow. So, instead of passing chars one by one, use RTOS msg to signal
that input data is available in FIFO, and then let task handler to read
data directly from FIFO.

With this change, lost chars problem is gone, but the pasted text is
truncated after some position. At least 500 chars can be pasted reliably
(at 115200 baud), but 1K never pastes completely.

0b32e50365 stmhal: Make pybstdio usable by other ports, and use it.
Now all ports can use pybstdio.c to provide sys.stdin/stdout/stderr, so
long as they implement mp_hal_stdin_* and mp_hal_stdout_* functions.

f12ea7c7ed esp8266: Implement task-based, event-driven interface with UART.
This enables proper interfacing with underlying OS - MicroPython doesn't
run the main loop, OS does, MicroPython just gets called when some event
takes place.
