7d2c685544 esp8266/scripts/_boot: Mount block device on "" instead of "/". 
"" is the correct name of the root directory when mounting a device there
(as opposed to "/").  One can now do os.listdir('/') and open('/abc'), as
well as os.listdir() and open('abc').

0a2e9650f5 py: Add ability to have frozen persistent bytecode from .mpy files. 
The config variable MICROPY_MODULE_FROZEN is now made of two separate
parts: MICROPY_MODULE_FROZEN_STR and MICROPY_MODULE_FROZEN_MPY.  This
allows to have none, either or both of frozen strings and frozen mpy
files (aka frozen bytecode).

19e3c9d53a esp8266/esp_mphal: Don't swallow exceptions in dupterm's read()/write(). 
The idea is that if dupterm object can handle exceptions, it will handle
them itself. Otherwise, object state can be compromised and it's better
to terminate dupterm session. For example, disconnected socket will keep
throwing exceptions and dump messages about that.

3177ef544f esp8266: In callback helpers, pop nlr_buf on successful call. 
nlr_pop must be called if no exception was raised.

Also, return value of these callback helpers is made void because ther
is (currently) no use for it.

40f5ecd3a8 esp8266: Add Python modules for initial configuration. 
Main entry point is _boot.py which checks whether FAT FS in flash mountable,
and if so, mounts it. Otherwise, it checks if flash is empty, and if so,
performs initial module setup: makes FAT FS, configures default AP name,
etc. As a last option, if flash is not empty, and could not be mounted,
it means filesystem corruption, and warning message with instructions is
printed in an infinite loop.

6e87aeb841 esp8266: Implement multistage bootstrap sequence. 
Upon start-up, _boot module is executed from frozen files to do early
initialization, e.g. create and mount the flash filesystem. Then
"boot.py" is executed if it exists in the filesystem. Finally, "main.py"
is executed if exists to allow start-on-boot user applications.

This allows a user to make a custom boot file or startup application
without recompiling the firmware, while letting to do early initialization
in Python code.

Based on RFC https://github.com/micropython/micropython/issues/1955.

With gap between segments minimized, there's not much padding to flash,
so no big speed overhead.

Paul Sokolovsky
8d2bcaf3cd esp8266: Minimize gap between Inst/DataRAM segments and FlashROM segment. 
With .rodata being in FlashROM now, gap can be much smaller now. InstRAM
can be max 32K, and with segment headers, that already makes it more than
32K. Then there's some .data still, and the next Flash page boundary is
0x9000. That figure should be more or less future-proof.

fb6cc96951 esp8266/uart: Comment out old, unused rx buffering code. 
This was originally used for non-event based REPL processing.  Then it
was unused when event-based processing was activated.  But now that event
based is disabled, and non-event based is back, there has been new ring
buffer code to process the chars.

Paul Sokolovsky
785cf9a61f esp8266: Support dedicated REPL loop (aka pull-style). 
Event-driven loop (push-style) is still supported and default (controlled
by MICROPY_REPL_EVENT_DRIVEN setting, as expected).

Dedicated loop worked even without adding ets_loop_iter(), though that
needs to be revisited later.

777232c9a5 esp8266: Disallow recursive calls to REPL. 
Before this change, if REPL blocked executing some code, it was possible
to still input new statememts and excuting them, all leading to weird,
and portentially dangerous interaction.

TODO: Current implementation may have issues processing input accumulated
while REPL was blocked.

4b597a1c1a esp8266: Reset term_obj on reboot. 
Also, term_obj can be NULL if socket enables REPL duplication signalling
before os.dupterm is called, so it should be checked.

Paul Sokolovsky
98af891610 esp8266: Implement input part of dupterm handling. 
The idea is following: underlying interrupt-driven or push-style data source
signals that more data is available for dupterm processing via call to
mp_hal_signal_dupterm_input(). This triggers a task which pumps data between
actual dupterm object (which may perform additional processing on data from
low-level data source) and input ring buffer.

Paul Sokolovsky
61fa7c8152 esp8266: Switch back to accumulating input data via ring buffer. 
But now it's generic ring buffer implemented via ringbuf.h, and is intended
for any type of input, including dupterm's, not just UART. The general
process work like this: an interrupt-driven input source puts data into
input_buf, and then signals new data available via call to
mp_hal_signal_input().

632d8efa05 esp8266: Add PWM support. 
PWM implementation uses a timer and interrupts (FRC1), taken from
Espressif's/NodeMCU's implementation and adapted for our use.

8 channels are supported, on pins 0, 2, 4, 5, 12, 13, 14, 15.

Usage:

    import machine
    pwm0 = machine.PWM(machine.Pin(0))
    pwm0.freq(1000)
    pwm0.duty(500)

Frequency is shared (ie the same) for all channels.  Frequency is
between 1 and 1000.  Duty is between 0 and 1023.

97375f4576 esp8266/ets_alt_task: Be sure to "pop" event before calling its handler.

97c2628900 esp8266: Add alternative event loop implementation. 
This implementation provides the same interface and uses the same
datastructures as used by BootROM, i.e. is a drop-in replacement for it.
But it offers one advantage: it allows to run single iteration of
event-pumping loop.

Original BootROM function are renamed, prefixed with underscore. There's
a switch which allows to use forward calls to them, for compatibility
testing.

The implementation also includes workarounds for hardware timer handler,
and these workarounds may be SDK version specific.

9e8396accb esp8266/modnetwork: Allow to configure STA and AP interfaces separately. 
On ESP8266, there're 2 different interfaces. Pretending it's not the case
desn't make sense. So, network.WLAN() now takes interface id, and returns
interface object. Individual operations are then methods of interface
object. Some operations require i/f of specific type (e.g. .connect()
makes sense only for STA), other are defined for any (e.g. .ifconfig(),
.mac()).

5b3f0b7f39 py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*. 
The first argument to the type.make_new method is naturally a uPy type,
and all uses of this argument cast it directly to a pointer to a type
structure.  So it makes sense to just have it a pointer to a type from
the very beginning (and a const pointer at that).  This patch makes
such a change, and removes all unnecessary casting to/from mp_obj_t.

Scenario: module1 depends on some common file from lib/, so specifies it
in its SRC_MOD, and the same situation with module2, then common file
from lib/ eventually ends up listed twice in $(OBJ), which leads to link
errors.

Make is equipped to deal with such situation easily, quoting the manual:
"The value of $^ omits duplicate prerequisites, while $+ retains them and
preserves their order." So, just use $^ consistently in all link targets.

2fc1e64319 esp8266: Fix lost chars problem when block-xfering data (e.g., when pasting). 
Pasting more or less sizable text into ESP8266 REPL leads to random chars
missing in the received input. Apparent cause is that using RTOS messages
to pass individual chars one by one is to slow and leads to UART FIFO
overflow. So, instead of passing chars one by one, use RTOS msg to signal
that input data is available in FIFO, and then let task handler to read
data directly from FIFO.

With this change, lost chars problem is gone, but the pasted text is
truncated after some position. At least 500 chars can be pasted reliably
(at 115200 baud), but 1K never pastes completely.

28076f3d4b esp8266: Fix garbage collector by hard-coding stack end address. 
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.

7f9d1d6ab9 py: Overhaul and simplify printf/pfenv mechanism. 
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.

0bfc7638ba py: Protect mp_parse and mp_compile with nlr push/pop block. 
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.
