Move webrepl support code from ports/esp8266/modules into extmod/webrepl
(to be alongside extmod/modwebrepl.c), and use frozen manifests to include
it in the build on esp8266 and esp32.
A small modification is made to webrepl.py to make it work on non-ESP
ports, i.e. don't call dupterm_notify if not available.
This is an alternative to f4ed2df that adds a newline so that the output of
the test starts on a new line and the result of the test is prefixed with
"result: " to distinguish it from the test output.

This reverts commit f4ed2dfa94.
This lets tinytest work as it was originally designed. An alternate
solution for the reverted commit will be implemented in a future commit.
This patch allows executing .mpy files (including native ones) directly on
a target, eg a board over a serial connection. So there's no need to copy
the file to its filesystem to test it.
For example:
$ mpy-cross foo.py
$ pyboard.py foo.mpy
- Corrected pin assignments and checked with CubeMX.
- Added additional I2C and UARTs.
- Added Ethernet interface definitions with lwIP and SSL support (but
Ethernet is currently unsupported on H7 MCUs so not fully enabled).
- Removed remarks on DFU/OCD in mpconfigboard.h because deploy-stlink works
fine too.
- Added more UARTs, I2C, corrected SPI, CAN, etc; verified against CubeMX.
- Adapted pins.csv to remove errors, add omissions, etc. according to
NUCLEO-144 User Manual.
- Changed linker file stm32f767.ld to reflect correct size of the Flash.
- Tested with LAN and SD card.
The Nucleo board does not have an SD card slot but does have the requisite
pins next to each other and labelled, so provide the configuration for
convenience.
This makes the loading of viper-code-with-relocations a bit neater and
easier to understand, by treating the rodata/bss like a special object to
be loaded into the constant table (which is how it behaves).
Because CPython 3.8.0 now produces different output:
- basics/parser.py: CPython does not allow '\\\n' as input.
- import/import_override: CPython imports _io.
We don't want to add a feature flag to .mpy files that indicate float
support because it will get complex and difficult to use. Instead the .mpy
is built using whatever precision it chooses (float or double) and the
native glue API will convert between this choice and what the host runtime
actually uses.
This commit adds a new tool called mpy_ld.py which is essentially a linker
that builds .mpy files directly from .o files. A new header file
(dynruntime.h) and makefile fragment (dynruntime.mk) are also included
which allow building .mpy files from C source code. Such .mpy files can
then be dynamically imported as though they were a normal Python module,
even though they are implemented in C.
Converting .o files directly (rather than pre-linked .elf files) allows the
resulting .mpy to be more efficient because it has more control over the
relocations; for example it can skip PLT indirection. Doing it this way
also allows supporting more architectures, such as Xtensa which has
specific needs for position-independent code and the GOT.
The tool supports targets of x86, x86-64, ARM Thumb and Xtensa (windowed
and non-windowed). BSS, text and rodata sections are supported, with
relocations to all internal sections and symbols, as well as relocations to
some external symbols (defined by dynruntime.h), and linking of qstrs.
Usage:
mpy-tool.py -o merged.mpy --merge mod1.mpy mod2.mpy
The constituent .mpy files are executed sequentially when the merged file
is imported, and they all use the same global namespace.
