bbccb0f630 esp8266: Remove scanning of GC pointers in native code block.
The native code no longer holds live GC pointers so doesn't need to be
scanned.

2e86233263 py/asm*: Remove ASM_MOV_REG_ALIGNED_IMM emit macro, it's no longer used.
After the previous commit this macro is no longer needed by the native
emitter because live heap pointers are no longer stored in generated native
machine code.

7d4b6cc868 py/emitnative: Place const objs for native code in separate const table.
This commit changes native code to handle constant objects like bytecode:
instead of storing the pointers inside the native code they are now stored
in a separate constant table (such pointers include objects like bignum,
bytes, and raw code for nested functions).  This removes the need for the
GC to scan native code for root pointers, and takes a step towards making
native code independent of the runtime (eg so it can be compiled offline by
mpy-cross).

Note that the changes to the struct scope_t did not increase its size: on a
32-bit architecture it is still 48 bytes, and on a 64-bit architecture it
decreased from 80 to 72 bytes.

217566b764 docs/library/network: Move specific network classes to their own file.
All concrete network classes are now moved to their own file (eg
network.WLAN.rst) and deconditionalised (remove ..only:: directives).  This
makes the network documentation the same for all ports.  After this change
there are no more "..only::" directives for different ports, and the only
difference among ports is the very front page of the docs.

b3eadf3f3d py/objfloat: Fix abs(-0.0) so it returns 0.0.
Nan and inf (signed and unsigned) are also handled correctly by using
signbit (they were also handled correctly with "val<0", but that didn't
handle -0.0 correctly).  A test case is added for this behaviour.

57a7d5be9a py: Fix msvc C++ compiler warnings with MP_OBJ_FUN_MAKE_SIG macro.
When obj.h is compiled as C++ code, the cl compiler emits a warning about
possibly unsafe mixing of size_t and bool types in the or operation in
MP_OBJ_FUN_MAKE_SIG.  Similarly there's an implicit narrowing integer
conversion in runtime.h.  This commit fixes this by being explicit.

a135bca4a1 py/objstr: format: Return bytes result for bytes format string.
This is an improvement over previous behavior when str was returned for
both str and bytes input format.  This new behaviour is also consistent
with how the % operator works, as well as many other str/bytes methods.

It should be noted that it's not how current versions of CPython work,
where there's a gap in the functionality and bytes.format() is not
supported.

8c656754aa py/modmath: Add math.factorial, optimised and non-opt implementations.
This commit adds the math.factorial function in two variants:
- squared difference, which is faster than the naive version, relatively
  compact, and non-recursive;
- a mildly optimised recursive version, faster than the above one.

There are some more optimisations that could be done, but they tend to take
more code, and more storage space.  The recursive version seems like a
sensible compromise.

The new function is disabled by default, and uses the non-optimised version
by default if it is enabled.  The options are MICROPY_PY_MATH_FACTORIAL
and MICROPY_OPT_MATH_FACTORIAL.

6ea6c7cc9e stm32/powerctrl: Don't configure clocks if already at desired frequency.
Configuring clocks is a critical operation and is best to avoid when
possible.  If the clocks really need to be reset to the same values then
one can pass in a slightly higher value, eg 168000001 Hz to get 168MHz.

1acf58c08f stm32/modmachine: Re-enable PLLSAI[1] after waking from stop mode.
On F7s PLLSAI is used as a 48MHz clock source if the main PLL cannot
provide such a frequency, and on L4s PLLSAI1 is always used as a clock
source for the peripherals.  This commit makes sure these PLLs are
re-enabled upon waking from stop mode so the peripherals work.

See issues #4022 and #4178 (L4 specific).

a2703649ea tools/pydfu: Workaround stdio flush error on Windows with Python 3.6.
There appears to be an issue on Windows with CPython >= 3.6,
sys.stdout.flush() raises an exception:

    OSError: [WinError 87] The parameter is incorrect

It works fine to just catch and ignore the error on the flush line.  Tested
on Windows 10 x64 1803 (Build 17134.228), Python 3.6.4 amd64.

b768cc6ca8 py/parsenum: Avoid rounding errors with negative powers-of-10.
This patches avoids multiplying with negative powers-of-10 when parsing
floating-point values, when those powers-of-10 can be exactly represented
as a positive power.  When represented as a positive power and used to
divide, the resulting float will not have any rounding errors.

The issue is that mp_parse_num_decimal will sometimes not give the closest
floating representation of the input string.  Eg for "0.3", which can't be
represented exactly in floating point, mp_parse_num_decimal gives a
slightly high (by 1LSB) result.  This is because it computes the answer as
3 * 0.1, and since 0.1 also can't be represented exactly, multiplying by 3
multiplies up the rounding error in the 0.1.  Computing it as 3 / 10, as
now done by the change in this commit, gives an answer which is as close to
the true value of "0.3" as possible.

This commit implements PEP479 which disallows raising StopIteration inside

should simply return when it is complete.
