cc7fece309 stm32/modnwwiznet5k: Release the GIL on blocking network operations.
connect, send, recv, sendto and recvfrom now release the GIL.  accept
already releases the GIL because it calls mp_hal_delay_ms() within its
busy-wait loop.

19f1b39d6f stm32/i2c: When scanning for I2C devices only do 1 probe per address.
Previous to this patch the i2c.scan() method would do up to 100 probes per
I2C address, to detect the devices on the bus.  This repeated probing was a
relic from when the code was copied from the accelerometer initialisation,
which requires to do repeated probes while waiting for the accelerometer
chip to turn on.

But I2C devices shouldn't need more than 1 probe to detect their presence,
and the generic software I2C implementation uses 1 probe successfully.  So
this patch changes the implementation to use 1 probe per address, which
significantly speeds up the scan operation.

b8ee7ab5b9 py/runtime0.h: Put inplace arith ops in front of normal operations.
This is to allow to place reverse ops immediately after normal ops, so
they can be tested as one range (which is optimization for reverse ops
introduction in the next patch).

c460f6f15a py/runtime0.h: Regroup operations a bit.
Originally, there were grouped in blocks of 5, to make it easier e.g.
to assess and numeric code of each. But now it makes more sense to
group it by semantics/properties, and then split in chunks still,
which usually leads to chunks of ~6 ops.

6d4cac088e py/objtype: Make sure mp_binary_op_method_name has full size again.
After recent refactorings to mp_binary_op_t, and make it future refactoring
proof for now, at the cost of extra element in the array.

50b9329eba py/runtime0.h: Move MP_BINARY_OP_DIVMOD to the end of mp_binary_op_t.
It starts a dichotomy of mp_binary_op_t values which can't appear in the
bytecode. Another reason to move it is to VALUES of OP_* and OP_INPLACE_*
nicely adjacent. This also will be needed for OP_REVERSE_*, to be soon
introduced.

d4d1c45a55 py/runtime0.h: Move relational ops to the beginning of mp_binary_op_t.

preparation to introduction of __rOP__ method support.

beeb7483d8 extmod/modussl_mbedtls: Allow to compile with MBEDTLS_DEBUG_C disabled.
With MBEDTLS_DEBUG_C disabled the function mbedtls_debug_set_threshold()
doesn't exist.  There's also no need to call mbedtls_ssl_conf_dbg() so a
few bytes can be saved on disabling that and not needing the mbedtls_debug
callback.

68c28174d0 py/objstr: Add check for valid UTF-8 when making a str from bytes.
This patch adds a function utf8_check() to check for a valid UTF-8 encoded
string, and calls it when constructing a str from raw bytes.  The feature
is selectable at compile time via MICROPY_PY_BUILTINS_STR_UNICODE_CHECK and
is enabled if unicode is enabled.  It costs about 110 bytes on Thumb-2, 150
bytes on Xtensa and 170 bytes on x86-64.

98da3cf407 stmhal: Fix clock initialisation of L4 MCUs.
There are 2 changes:
- remove early initialisation of LSE and replaced it by LSEDRIVE config
  (there is no reason to call HAL_RCC_OscConfig twice).
- add initialisation of the variables PLLSAI1Source and PLLSAI1M as they
  are needed in Cube HAL 1.8.1.

d4b75f6b68 py/obj: Fix comparison of float/complex NaN with itself.
IEEE floating point is specified such that a comparison of NaN with itself
returns false, and Python respects these semantics.  This patch makes uPy
also have these semantics.  The fix has a minor impact on the speed of the
object-equality fast-path, but that seems to be unavoidable and it's much
more important to have correct behaviour (especially in this case where
the wrong answer for nan==nan is silently returned).

9950865c39 py/objfloat: Fix binary ops with incompatible objects.
These are now returned as "operation not supported" instead of raising
TypeError. In particular, this fixes equality for float vs incompatible
types, which now properly results in False instead of exception. This
also paves the road to support reverse operation (e.g. __radd__) with
float objects.

This is achieved by introducing mp_obj_get_float_maybe(), similar to
existing mp_obj_get_int_maybe().

2daacc5cee py/modstruct: Check and prevent buffer-write overflow in struct packing.
Prior to this patch, the size of the buffer given to pack_into() was checked
for being too small by using the count of the arguments, not their actual
size.  For example, a format spec of '4I' would only check that there was 4
bytes available, not 16; and 'I' would check for 1 byte, not 4.

The pack() function is ok because its buffer is created to be exactly the
correct size.

The fix in this patch calculates the total size of the format spec at the
start of pack_into() and verifies that the buffer is large enough.  This
adds some computational overhead, to iterate through the whole format spec.
The alternative is to check during the packing, but that requires extra
code to handle alignment, and the check is anyway not needed for pack().
So to maintain minimal code size the check is done using struct_calcsize.

79d5acbd01 py/modstruct: Check and prevent buffer-read overflow in struct unpacking
Prior to this patch, the size of the buffer given to unpack/unpack_from was
checked for being too small by using the count of the arguments, not their
actual size.  For example, a format spec of '4I' would only check that
there was 4 bytes available, not 16; and 'I' would check for 1 byte, not 4.

This bug is fixed in this patch by calculating the total size of the format
spec at the start of the unpacking function.  This function anyway needs to
calculate the number of items at the start, so calculating the total size
can be done at the same time.

793d826d9d py/modstruct: In struct.pack, stop converting if there are no args left.
This patch makes a repeat counter behave the same as repeating the
typecode, when there are not enough args.  For example:
struct.pack('2I', 1) now behave the same as struct.pack('II', 1).

8388ec4e35 stmhal: Update to new STM Cube HAL library.
This upgrades the HAL to the versions:
- F4 V1.16.0
- F7 V1.7.0
- L4 V1.8.1

The main changes were in the SD card driver.  The vendor changed the SD
read/write functions to accept block number intead of byte address, so
there is no longer any need for a custom patch for this in stm32lib.
The CardType values also changed, so pyb.SDCard().info() will return
different values for the 3rd element of the tuple, but this function was
never documented.
