5c32111fa0 ports: Reformat more C and Python source code.
These files that are reformatted only now fall under the list of files to
apply uncrustify/black formatting to.

95ee29f4f4 stm32/mbedtls: Add NULL pointer check in m_free_mbedtls.

5e506567a3 stm32/mbedtls: Enable MBEDTLS_TLS_DEFAULT_ALLOW_SHA1_IN_KEY_EXCHANGE.
This adds MBEDTLS_MD_SHA1 to the list of default hashes for TLS 1.2
handshake signatures.  Although SHA-1 is weak, this option is turned on in
the default mbedtls configuration file, and allows better compatibility
with older servers.  In particular it allows an stm32-mbedtls-based client
to connect to an axtls-based client (eg default unix port and esp8266).

5264478007 extmod/modussl_mbedtls: Integrate shorter error strings.
The stm32 and esp32 ports now use shorter error strings for mbedtls errors.
Also, MBEDTLS_ERROR_C is enabled on stm32 by default to get these strings.

fed4c23590 stm32: Integrate optional mbedTLS component for ussl module.
To use it a board should define MICROPY_PY_USSL=1 and MICROPY_SSL_MBEDTLS=1
at the Makefile level.  With the provided configuration it adds about 64k
to the build.
