a1f2245a81 py/vstr: vstr_null_terminated_str(): Extend string by at most one byte. 
vstr_null_terminated_str is almost certainly a vstr finalization operation,
so it should add the requested NUL byte, and not try to pre-allocate more.
The previous implementation could actually allocate double of the buffer
size.

6de8dbb488 py/objstr: .format(): Avoid call to vstr_null_terminated_str(). 
By comparing with string end pointer instead of checking for NUL byte.
Should alleviate reallocations and fragmentation a tiny bit.

460b086333 py/mpz: Fix mpn_div so that it doesn't modify memory of denominator. 
Previous to this patch bignum division and modulo would temporarily
modify the RHS argument to the operation (eg x/y would modify y), but on
return the RHS would be restored to its original value.  This is not
allowed because arguments to binary operations are const, and in
particular might live in ROM.  The modification was to normalise the arg
(and then unnormalise before returning), and this patch makes it so the
normalisation is done on the fly and the arg is now accessed as read-only.

This change doesn't increase the order complexity of the operation, and
actually reduces code size.

de5e0ed2e0 esp8266/main: Bump heap size to 28K. 
This is kind of compensation for 4K FatFs buffer size which is eaten away
from it on FS mount. This should still leave enough of networking ("OS")
heap.

65402ab1ec py/mpz: Do Python style division/modulo within bignum divmod routine. 
This patch consolidates the Python logic for division/modulo to one place
within the bignum code.

dc3faea040 py/mpz: Fix bug with overflowing C-shift in division routine. 
When DIG_SIZE=32, a uint32_t is used to store limbs, and no normalisation
is needed because the MSB is already set, then there will be left and
right shifts (in C) by 32 of a 32-bit variable, leading to undefined
behaviour.  This patch fixes this bug.

d59c2e5e45 py/repl: If there're no better alternatives, try to complete "import". 
Also do that only for the first word in a line. The idea is that when you
start up interpreter, high chance that you want to do an import. With this
patch, this can be achieved with "i<tab>".

87106d025b windows: Enable multi-processor compilation for msvc 
This will launch about as many compiler instances as there are logical
processors on a machine, and as such significantly speeds up compilation.

12dd8df375 py/objstr: Binary type of str/bytes for buffer protocol is 'B'. 
The type is an unsigned 8-bit value, since bytes objects are exactly
that.  And it's also sensible for unicode strings to return unsigned
values when accessed in a byte-wise manner (CPython does not allow this).

8db61e5b5a esp8266/scripts/inisetup: Don't start WebREPL on boot in master branch. 
It interferes with running testsuite. master branch should be optimized for
development, so any features which interfere with that, would need to be
disabled by default.

e64032d6fd stmhal: L4: Adapt DMA to be able to support STM32L4 MCU series. 
The main thing is to change the DMA code in a way that the structure
DMA_Stream_TypeDef (which is similar to DMA_Channel_TypeDef on stm32l4)
is no longer used outside of dma.c, as this structure only exists for the
F4 series.  Therefore I introduced a new structure (dma_descr_t) which
handles all DMA specific stuff for configuration.  Further the periphery
(spi, i2c, sdcard, dac) does not need to know the internals of the dma.
