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.

959ed931a4 esp8266/esp_mphal: call_dupterm_read(): Fix order of deactivating on EOF.
First deactivate, then print diagnostic message.

19e3c9d53a esp8266/esp_mphal: Don't swallow exceptions in dupterm's read()/write().
The idea is that if dupterm object can handle exceptions, it will handle
them itself. Otherwise, object state can be compromised and it's better
to terminate dupterm session. For example, disconnected socket will keep
throwing exceptions and dump messages about that.

785cf9a61f esp8266: Support dedicated REPL loop (aka pull-style).
Event-driven loop (push-style) is still supported and default (controlled
by MICROPY_REPL_EVENT_DRIVEN setting, as expected).

Dedicated loop worked even without adding ets_loop_iter(), though that
needs to be revisited later.

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().

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, "...");

8ab16b6af0 esp8266: Add custom _assert() function.
Enabling standard assert() (by removing -DNDEBUG) produces non-bootable
binary (because all messages go to .rodata which silently overflows).
So, for once-off debugging, have a custom _assert().

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).

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.
