dce590c29d lib/mp-readline: Add an assert() to catch buffer overflows.
During readline development, this function may receive bad `pos` values.
It's easier to understand the assert() failing error than to have a "stack
smashing detected" message.

bc5c993adf docs/README: Add short paragraph about using readthedocs.
This adds a short paragraph on how to hook readthedocs.org up.  The main
goal is to make people aware of the option, to help with contributing to
the documentation.

977b532c8f unix: Rename unix binaries to micropython-variant (not _variant).

2357338e93 unix: Add placeholder DEV variant with settrace enabled.
This will eventually become the "full featured" unix binary with more
features enabled, specifically useful for development and testing.

bd2fff6687 unix: Add build variants, analogous to boards on bare-metal.
Invoking "make" will still build the standard "micropython" executable, but
other variants are now build using, eg, "make VARIANT=minimal".  This
follows how bare-metal ports specify a particular board, and allows running
any make target (eg clean, test) with any variant.

Convenience targets (eg "make coverage") are provided to retain the old
behaviour, at least for now.

See issue #3043.

7d2ccd027f py/mkenv.mk: Move usage of 32-bit flags to py.mk.
This allows ports/variants to configure MICROPY_FORCE_32BIT after including
mkenv.mk, but before py.mk.

bfbd94401d py: Make mp_obj_get_type() return a const ptr to mp_obj_type_t.
Most types are in rodata/ROM, and mp_obj_base_t.type is a constant pointer,
so enforce this const-ness throughout the code base.  If a type ever needs
to be modified (eg a user type) then a simple cast can be used.

e3187b052f stm32/boards/PYBD: Change RTC asynch prediv from 1 to 4.
This change has the following effects:
- Reduces the resolution of the RTC sub-second counter from 30.52us to
  122.07us.
- Allows RTC.calibration() to now support positive values (as well as
  negative values).
- Reduces VBAT current consumption in standby mode by a small amount.

For general purpose use 122us resolution of the sub-second counter is
good enough, and the benefits of full range calibration and minor reduction
in VBAT consumption are worth the change.

54a2584de1 tests/unix: Make unix time test pass on more platforms.
As the mktime documentation for CPython states: "The earliest date for
which it can generate a time is platform-dependent".  In particular on
Windows this depends on the timezone so e.g. for UTC+2 the earliest is 2
hours past midnight January 1970.  So change the reference to the earliest
possible, for UTC+14.

99b8c1a937 esp32/Makefile: Assign result of $call to dummy var for older make.
Make version 4.1 and lower does not allow $call as the main expression on a
line, so assign the result of the $call to a dummy variable.

Fixes issue #5426.

1bc9fc8082 tests/run-tests: Handle 'CRASH' return by float.py feature test.
It is possile for `run_feature_check(pyb, args, base_path, 'float.py')` to
return `b'CRASH'`.  This causes an unhandled exception in `int()`.

This commit fixes the problem by first testing for `b'CRASH'` before trying
to convert the return value to an integer.

4c93955b7b py/objslice: Add support for indices() method on slice objects.
Instances of the slice class are passed to __getitem__() on objects when
the user indexes them with a slice.  In practice the majority of the time
(other than passing it on untouched) is to work out what the slice means in
the context of an array dimension of a particular length.  Since Python 2.3
there has been a method on the slice class, indices(), that takes a
dimension length and returns the real start, stop and step, accounting for
missing or negative values in the slice spec.  This commit implements such
a indices() method on the slice class.

It is configurable at compile-time via MICROPY_PY_BUILTINS_SLICE_INDICES,
disabled by default, enabled on unix, stm32 and esp32 ports.

This commit also adds new tests for slice indices and for slicing unicode
strings.

269c9a08b6 unix/modos: Add uos.rename and uos.rmdir.
The existing uos.remove cannot be used to remove directories, instead
uos.rmdir is needed.  And also provide uos.rename to get a good set of
filesystem functionality without requiring additional Python-level os
functions (eg using ffi).

b23bd6433c py: Clean up commented-out code and comments about exception hierarchy.
In CPython, EnvironmentError and IOError are now aliases of OSError so no
need to have them listed in the code.  OverflowError inherits from
ArithmeticError because it's intended to be raised "when the result of an
arithmetic operation is too large to be represented" (per CPython docs),
and MicroPython aims to match the CPython exception hierarchy.

61d2b40ad5 lib/utils/pyexec: Introduce MICROPY_REPL_INFO, wrap debug prints in it.
For the 3 ports that already make use of this feature (stm32, nrf and
teensy) this doesn't make any difference, it just allows to disable it from
now on.

For other ports that use pyexec, this decreases code size because the debug
printing code is dead (it can't be enabled) but the compiler can't deduce
that, so code is still emitted.

d56bc6e03d py/obj.h: Use 32-bit shift in MP_OBJ_NEW_QSTR calc for obj-repr D.
The qst value is always small enough to fit in 31-bits (even less) and
using a 32-bit shift rather than a 64-bit shift reduces code size by about
300 bytes.

Also, native emitters will be disabled.

aacd618939 py/runtime: Don't allocate iter buf for user-defined types.
A user-defined type that defines __iter__ doesn't need any memory to be
pre-allocated for its iterator (because it can't use such memory).  So
optimise for this case by not allocating the iter-buf.

instruction, and avoiding any compiler warnings.
