b7768a74a7 atmel-samd: Fix file system init. 
Adding the USB write protection prevented file system reset from
working. Since it happens before USB start we temporarily set the
volume to writeable and then set it back to read-only before USB is
started.

984a867341 esp8266/scripts: Make neopixel/apa102 handle 4bpp LEDs with common code. 
The NeoPixel class now handles 4 bytes-per-pixel LEDs (extra byte is
intensity) and arbitrary byte ordering.  APA102 class is now derived from
NeoPixel to reduce code size and support fill() operation.

2550d7dfd2 esp8266: Add support for building firmware version for 512K modules. 
To build, "make 512k".

Disabled are FatFs support (no space for filesystem), Python functionality
related to files, btree module, and recently enabled features. With all
this, there's only one free FlashROM page.

e6af94d13b esp8266/modesp: Add flash_user_start() function. 
As we're looking towards adding OTA support, calculation of a FlashROM
area which can be used for filesystem (etc.) may become complex, so
introduce C function for that. So far it just hardcodes current value,
0x90000. In the future the function may be extended (and renamed) to
return the size of area too.

479b961d39 zephyr: Implement utime module. 
This provides time and sleep together with the usual ticks_us/_ms/_diff
and sleep_us/ms family.

We also provide access to Zephyr's high precision timer as ticks_cpu().

571e6f26db py: Specialise builtin funcs to use separate type for fixed arg count. 
Builtin functions with a fixed number of arguments (0, 1, 2 or 3) are
quite common.  Before this patch the wrapper for such a function cost
3 machine words.  After this patch it only takes 2, which can reduce the
code size by quite a bit (and pays off even more, the more functions are
added).  It also makes function dispatch slightly more efficient in CPU
usage, and furthermore reduces stack usage for these cases.  On x86 and
Thumb archs the dispatch functions are now tail-call optimised by the
compiler.

The bare-arm port has its code size increase by 76 bytes, but stmhal drops
by 904 bytes.  Stack usage by these builtin functions is decreased by 48
bytes on Thumb2 archs.

4ebdb1f2b2 py: Be more specific with MP_DECLARE_CONST_FUN_OBJ macros. 
In order to have more fine-grained control over how builtin functions are
constructed, the MP_DECLARE_CONST_FUN_OBJ macros are made more specific,
with suffix of _0, _1, _2, _3, _VAR, _VAR_BETEEN or _KW.  These names now
match the MP_DEFINE_CONST_FUN_OBJ macros.
