ff1a96ce2c py/mpz: Add commented-out mpz_pow3_inpl function, to compute (x**y)%z.
This function computes (x**y)%z in an efficient way.  For large arguments
this operation is otherwise not computable by doing x**y and then %z.

It's currently not used, but is added in case it's useful one day.

2e2e15cec2 py/mpz: Complete implementation of mpz_{and,or,xor} for negative args.
For these 3 bitwise operations there are now fast functions for
positive-only arguments, and general functions for arbitrary sign
arguments (the fast functions are the existing implementation).

By default the fast functions are not used (to save space) and instead
the general functions are used for all operations.

Enable MICROPY_OPT_MPZ_BITWISE to use the fast functions for positive
arguments.

5f3e005b67 py: Extend native type-sig to use 4 bits, so uint is separate to ptr.
Before this patch, the native types for uint and ptr/ptr8/ptr16/ptr32
all overlapped and it was possible to make a mistake in casting.  Now,
these types are all separate and any coding mistakes will be raised
as runtime errors.

e3a29de1dc py/objstr: For str.format, add nested/computed fields support.
Eg: '{:{}}'.format(123, '>20')

@pohmelie was the original author of this patch, but @dpgeorge made
significant changes to reduce code size and improve efficiency.

ea040a4f9a stmhal: In HAL I2C driver, move DMA setup to after sending I2C address.
Previous to this patch the DMA was setup and then the I2C address sent.
If the I2C address sending failed (eg no I2C device on the bus) then the
DMA was left in an inconsistent state.

This patch moves the DMA setup to after a successful sending of the I2C
address(es).

See issue #1765.

a8a4b01af6 stmhal: Add PWM capability for LED(3) and LED(4) on pyboards.
USB CDC no longer needs TIM3 (which was originally used for LED(4) PWM)
and so TIM3 has been freed for general purpose use by the user.  Hence
LED(4) lost its PWM capabilities.

This patch reinstates the PWM capabilities using a semi-generic piece
of code which allows to configure a timer and PWM channel to use for any
LED.  But the PWM capability is only configured if the LED is set to an
intensity between 1 and 254 (ie only when needed).  In that case the
relevant timer is configured for PWM.  It's up to the user to make sure
the timers are not used if PWM is active.

This patch also makes sure that PWM LEDs are turned off using standard
GPIO when calling led.off() or led.intensity(0), instead of just setting
the PWM counter to zero.

ea89b80ff4 stmhal: Make TIM3 available for use by the user.
TIM3 is no longer used by USB CDC for triggering outgoing data, so we
can now make it available to the user.

PWM fading on LED(4) is now gone, but will be reinstated in a new way.

d363133917 stmhal: Make USB CDC driver use SOF instead of TIM3 for outgoing data.
Previous to this patch the USB CDC driver used TIM3 to trigger the
sending of outgoing data over USB serial.  This patch changes the
behaviour so that the USB SOF interrupt is used to trigger the processing
of the sending.  This reduces latency and increases bandwidth of outgoing
data.

Thanks to Martin Fischer, aka @hoihu, for the idea and initial prototype.

See PR #1713.

7417ccfb0d py/formatfloat: Add ability to format doubles with exponents > 99.
For single prec, exponents never get larger than about 37.  For double
prec, exponents can be larger than 99 and need 3 bytes to format.  This
patch makes the number of bytes needed configurable.

Addresses issue #1772.

d3b1f0b627 py/runtime: mp_stack_ctrl_init() should be called immediately on startup.
Calling it from mp_init() is too late for some ports (like Unix), and leads
to incomplete stack frame being captured, with following GC issues. So, now
each port should call mp_stack_ctrl_init() on its own, ASAP after startup,
and taking special precautions so it really was called before stack variables
get allocated (because if such variable with a pointer is missed, it may lead
to over-collecting (typical symptom is segfaulting)).

6a804cbaba lib/utils/printf: Fix printf on release builds
When using newer glibc's the compiler automatically sets
_FORTIFY_SOURCE when building with -O1 and this causes
a special inlined version of printf to be declared which
then bypasses our version of printf.

7b05b1b225 py/bc: Update opcode format table now that MP_BC_NOT opcode is gone.
MP_BC_NOT was removed and the "not" operation made a proper unary
operator, and the opcode format table needs to be updated to reflect
this change (but actually the change is only cosmetic).

ee1656e148 extmod/moduhashlib: Add support for SHA1 (based on axTLS).
SHA1 is used in a number of protocols and algorithm originated 5 years ago
or so, in other words, it's in "wide use", and only newer protocols use
SHA2.

The implementation depends on axTLS enabled. TODO: Make separate config
option specifically for sha1().

df4ce930e3 py/modmicropython: Add stack_use, heap_lock and heap_unlock functions.
micropython.stack_use() returns an integer being the number of bytes used
on the stack.

micropython.heap_lock() and heap_unlock() can be used to prevent the
memory manager from allocating anything on the heap.  Calls to these are
allowed to be nested.

42a6364a31 stmhal: Add support for building frozen files.
This allows FROZEN_DIR=some-directory to be specified on the make
command line, which will then add all of the files contained within
the indicated frozen directory as frozen files in the image.

There is no change in flash/ram usage if not using the feature.

This is especially useful on smaller MCUs (like the 401) which only
has 64K flash file system.
