1f1a54d0b1 py/repl: Filter private methods from tab completion.
Anything beginning with "_" will now only be tab-completed if there is
already a partial match for such an entry.  In other words, entering
foo.<tab> will no longer complete/list anything beginning with "_".

6b7c8d3e72 py/runtime: Remove commented-out code from mp_deinit().
These commented-out lines of code have been unused for a long time, so
remove them to avoid confusion as to why they are there.

mp_obj_dict_free() never existed, this line was converted from
mp_map_deinit() and commented out as soon as it was added.  The call to
mp_map_deinit(mp_loaded_modules_map) was commented in
1a1d11fa32.

3c4bfd1dec py/objexcept: Support errno attribute on OSError exceptions.
This commit adds the errno attribute to exceptions, so code can retrieve
errno codes from an OSError using exc.errno.

The implementation here simply lets `errno` (and the existing `value`)
attributes work on any exception instance (they both alias args[0]).  This
is for efficiency and to keep code size down.  The pros and cons of this
are:

Pros:
- more compatible with CPython, less difference to document and learn
- OSError().errno will correctly return None, whereas the current way of
  doing it via OSError().args[0] will raise an IndexError
- it reduces code size on most bare-metal ports (because they already have
  the errno qstr)
- for Python code that uses exc.errno the generated bytecode is 2 bytes
  smaller and more efficient to execute (compared with exc.args[0]); so
  bytecode loaded to RAM saves 2 bytes RAM for each use of this attribute,
  and bytecode that is frozen saves 2 bytes flash/ROM for each use
- it's easier/shorter to type, and saves 2 bytes of space in .py files that
  use it (for each use)

Cons:
- increases code size by 4-8 bytes on minimal ports that don't already have
  the `errno` qstr
- all exceptions now have .errno and .value attributes (a cpydiff test is
  added to address this)

0cf12dd59c rp2: Add support for USER_C_MODULES to CMake build system.
The parts that are generic are added to py/ so they can be used by other
ports that use CMake.

py/usermod.cmake:

* Creates a usermod target to hang user C/CXX modules from.
* Gathers sources from user C/CXX modules and libs for QSTR scan.

ports/rp2/CMakeLists.txt:

* Includes py/usermod.cmake.
* Links the resulting usermod library to the MicroPython target.

py/mkrules.cmake:

Add cxxflags to qstr.i.last custom command for CXX modules:

* MICROPY_CPP_FLAGS so CXX modules will find includes.
* -DNO_QSTR to fix fatal error missing "genhdr/qstrdefs.generated.h".

Usage:

The rp2 port can be linked against user C modules by running:

make USER_C_MODULES=/path/to/module/micropython.cmake

CMake will print a list of included modules.

0a59938574 py/mpz: Fix overflow of borrow in mpn_div.
For certain operands to mpn_div, the existing code path for
`DIG_SIZE == MPZ_DBL_DIG_SIZE / 2` had a bug in it where borrow could still
overflow in the `(x >= *n || *n - x <= borrow)` branch, ie
`borrow + x - (mpz_dbl_dig_t)*n` overflows the borrow variable.  In such
cases the subsequent right-shift of borrow would not bring in the overflow
bit, leading to an error in the result.  An example division that had
overflow when MPZ_DIG_SIZE = 16 is `(2 ** 48 - 1) ** 2 // (2 ** 48 - 1)`.

This is fixed in this commit by simplifying the code and handling the low
digits of borrow first, and then the upper bits (to shift down) separately.
There is no longer a distinction between `DIG_SIZE < MPZ_DBL_DIG_SIZE / 2`
and `DIG_SIZE == MPZ_DBL_DIG_SIZE / 2`.

This commit also simplifies the second part of the calculation so that
borrow does not need to be negated (instead the code just works knowing
that borrow is negative and using + instead of - in calculations involving
borrow).

Fixes #6777.

ad4656b861 all: Rename BYTES_PER_WORD to MP_BYTES_PER_OBJ_WORD.
The "word" referred to by BYTES_PER_WORD is actually the size of mp_obj_t
which is not always the same as the size of a pointer on the target
architecture.  So rename this config value to better reflect what it
measures, and also prefix it with MP_.

For uses of BYTES_PER_WORD in setting the stack limit this has been
changed to sizeof(void *), because the stack usually grows with
machine-word sized values (eg an nlr_buf_t has many machine words in it).

5020b14d54 py/mpprint: Fix length calculation for strings with precision-modifier.
Two issues are tackled:

1. The calculation of the correct length to print is fixed to treat the
   precision as a maximum length instead as the exact length.
   This is done for both qstr (%q) and for regular str (%s).

2. Fix the incorrect use of mp_printf("%.*s") to mp_print_strn().

   Because of the fix of above issue, some testcases that would print
   an embedded null-byte (^@ in test-output) would now fail.
   The bug here is that "%s" was used to print null-bytes. Instead,
   mp_print_strn is used to make sure all bytes are outputted and the
   exact length is respected.

Test-cases are added for both %s and %q with a combination of precision
and padding specifiers.
