777232c9a5 esp8266: Disallow recursive calls to REPL. 
Before this change, if REPL blocked executing some code, it was possible
to still input new statememts and excuting them, all leading to weird,
and portentially dangerous interaction.

TODO: Current implementation may have issues processing input accumulated
while REPL was blocked.

4b597a1c1a esp8266: Reset term_obj on reboot. 
Also, term_obj can be NULL if socket enables REPL duplication signalling
before os.dupterm is called, so it should be checked.

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().

2599672384 py/parsenum: Use pow function to apply exponent to decimal number. 
Pow is already a dependency when compiling with floats, so may as well
use it here to reduce code size and speed up the conversion for most
cases.

03b8bb7ec9 py/formatfloat: Fix case of float format where leading digit was "10". 
When taking the logarithm of the float to determine the exponent, there
are some edge cases that finish the log loop too large.  Eg for an
input value of 1e32-epsilon, this is actually less than 1e32 from the
log-loop table and finishes as 10.0e31 when it should be 1.0e32.  It
is thus rendered as :e32 (: comes after 9 in ascii).

There was the same problem with numbers less than 1.

13394a632d unix/unix_mphal: Hack to make uos.dupterm() actually work. 
See https://github.com/micropython/micropython/issues/1736 for the
list of complications. This workaround instead of duplicating REPL
to another stream, switches to it, because read(STDIN) we use otherwise
is blocking call, so it and custom REPL stream can't be used together.

632d8efa05 esp8266: Add PWM support. 
PWM implementation uses a timer and interrupts (FRC1), taken from
Espressif's/NodeMCU's implementation and adapted for our use.

8 channels are supported, on pins 0, 2, 4, 5, 12, 13, 14, 15.

Usage:

    import machine
    pwm0 = machine.PWM(machine.Pin(0))
    pwm0.freq(1000)
    pwm0.duty(500)

Frequency is shared (ie the same) for all channels.  Frequency is
between 1 and 1000.  Duty is between 0 and 1023.
