Moved modesp.o to flash and increased size of the irom0_0_seg segment. The new
value was taken from NodeMCU linker script.

The function passed to socket.onsent() gets called after data is succesfully
sent by the socket.

This was causing crashes in .onconnect()

As user_init() is not a true main functions, the stack pointer captured within
is not pointing at the base of the stack. This caused gc_collect being called
with sp being higher than stack_end, causing integer overflow and crashing as
gc tried to scan almost the entire address space.

esp8266 port now has working raw and friendly REPL, as well as working
soft reset (CTRL-D at REPL, or raise SystemExit).
tools/pyboard.py now works with esp8266 port.

* UDP currently not supported
* As there is no way (that I know of) the espconn_regist_connectcb()
callback can recognize on which socket has the connection arrived,
only one listening function at a time is supported

Previous to this patch the printing mechanism was a bit of a tangled
mess. This patch attempts to consolidate printing into one interface.
All (non-debug) printing now uses the mp_print* family of functions,
mainly mp_printf. All these functions take an mp_print_t structure as
their first argument, and this structure defines the printing backend
through the "print_strn" function of said structure.
Printing from the uPy core can reach the platform-defined print code via
two paths: either through mp_sys_stdout_obj (defined pert port) in
conjunction with mp_stream_write; or through the mp_plat_print structure
which uses the MP_PLAT_PRINT_STRN macro to define how string are printed
on the platform. The former is only used when MICROPY_PY_IO is defined.
With this new scheme printing is generally more efficient (less layers
to go through, less arguments to pass), and, given an mp_print_t*
structure, one can call mp_print_str for efficiency instead of
mp_printf("%s", ...). Code size is also reduced by around 200 bytes on
Thumb2 archs.

Now all ports can use pybstdio.c to provide sys.stdin/stdout/stderr, so
long as they implement mp_hal_stdin_* and mp_hal_stdout_* functions.

To enable parsing constants more efficiently, mp_parse should be allowed
to raise an exception, and mp_compile can already raise a MemoryError.
So these functions need to be protected by an nlr push/pop block.
This patch adds that feature in all places. This allows to simplify how
mp_parse and mp_compile are called: they now raise an exception if they
have an error and so explicit checking is not needed anymore.

Just always keep jumper in bootloader position. After flashing, uPy
automatically executed. And to get back to bootloader, do "make reset".

So far implements .scan(lambda x: print(x)) function to scan for WiFi access
points.

This enables proper interfacing with underlying OS - MicroPython doesn't
run the main loop, OS does, MicroPython just gets called when some event
takes place.

We cannot assume that all memory belongs to us - it actually belongs to
ESP8266 OS.

A GC in stmhal port now only scans true root pointers, not entire BSS.
This reduces base GC time from 1700ms to 900ms.

This patch consolidates all global variables in py/ core into one place,
in a global structure. Root pointers are all located together to make
GC tracing easier and more efficient.

This is just a clean-up of the code. Generated code is exactly the
same.

rodata can only go in iram/irom if it's accessed only using word loads
(ie no byte or half-word access).
|

When esp-open-sdk is built with STANDALONE=y (the default) then ESP_SDK
is set to the correct value, so that "make" just works.
|

Some rodata items can go in iram/irom segment, but not others. With
this patch ESP now has 24256 bytes of heap ram. It passes 228 out of
248 tests from tests/basics directory.
