7437215ad7 stm32/modnetwork: Change base entry of NIC object from type to base. 
mod_network_nic_type_t doesn't need to be an actual uPy type, it just needs
to be an object.

6d87aa54d6 stm32/modnetwork: Don't take netif's down when network is deinited. 
It should be up to the NIC itself to decide if the network interface is
removed upon soft reset.  Some NICs can keep the interface up over a soft
reset, which improves usability of the network.

ea22406f76 extmod/modussl_mbedtls: Use mbedtls_entropy_func for CTR-DRBG entropy. 
If mbedtls_ctr_drbg_seed() is available in the mbedtls bulid then so should
be mbedtls_entropy_func().  Then it's up to the port to configure a valid
entropy source, eg via MBEDTLS_ENTROPY_HARDWARE_ALT.

98b9f0fc9d extmod/modussl_mbedtls: Populate sock member right away in wrap_socket. 
Otherwise the "sock" member may have an undefined value if wrap_socket
fails with an exception and exits early, and then if the finaliser runs it
will try to close an invalid stream object.

Fixes issue #3828.

c60589c02b py/objtype: Fix assertion failures in super_attr by checking type.

05b13fd292 py/objtype: Fix assertion failures in mp_obj_new_type by checking types. 
Fixes assertion failures when the arguments to type() were not of valid
types, e.g., when making calls like:

    type("", (), 3)
    type("", 3, {})

50bc34d4a4 stm32/boards: Split combined alt-func labels and fix some other errors. 
Pins with multiple alt-funcs for the same peripheral (eg USART_CTS_NSS)
need to be split into individual alt-funcs for make-pins.py to work
correctly.

This patch changes the following:
- Split `..._CTS_NSS` into `..._CTS/..._NSS`
- Split `..._RTS_DE` into `..._RTS/..._DE`
- Split `JTDO_SWO` into `JTDO/TRACESWO` for consistency
- Fixed `TRACECK` to `TRACECLK` for consistency

f497723802 stm32: Allow to have no storage support if there are no block devices. 
If no block devices are defined by a board then storage support will be
disabled.  This means there is no filesystem provided by either the
internal flash or external SPI flash.  But the VFS system can still be
enabled and filesystems provided on external devices like an SD card.

cda964198a stm32: Integrate lwIP as implementation of usocket module. 
This patch allows to use lwIP as the implementation of the usocket module,
instead of the existing socket-multiplexer that delegates the entire TCP/IP
layer to the NIC itself.

This is disabled by default, and enabled by defining MICROPY_PY_LWIP to 1.

When enabled, the lwIP TCP/IP stack will be included in the build with
default settings for memory usage and performance (see
lwip_inc/lwipopts.h).  It is then up to a particular NIC to register itself
with lwIP using the standard lwIP netif API.

operation using modulo arithmetic rules.
