Features inline get/put operations for the highest performance. Locking
is not part of implementation, operation should be wrapped with locking
externally as needed.

That is: aps = if0.scan()

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

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.

Includes extensive test cases to catch hopefully all cases where
buffer might overflow.

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.

That's definitely helpful for debugging.

Helpful when debugging dupterm support (because otherwise all output is
spooled to dupterm too).

To use:

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

Uses what is suspected to be a hardware random number generator.

Otherwise device stays mounted on soft reset and leads to corruption
(since block device object is now gone).

I.e. os.listdir(...) will redirect to
MP_STATE_PORT(fs_user_mount)[0].listdir(...).

Most esp8266 modules have at least 1MB (8Mbit) of flash. If not set, vendor
functions allow to access only first 512K.

Otherwise, events may be posted to non-initialized task, which leads to
segfaults.

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.
