This partially implements adafruit#8675. Releasing non-primary displays is left for a 10.0 incompatible change. The allocation of I2C and SPI bus objects is unchanged, rather than allocating them outside the GC heap as suggested in that PR.
This can be enabled on additional boards provided the board: * has a HSTX or DVI connector built in * connects the primary I2C bus to this connector * has pull-ups on this connector * for RP2040, a `preflight` function needs to be written to check the requested resolution is valid If a DVI display is configured, it will be set as the primary display and be available as `supervisor.runtime.display`. It will not be `board.DISPLAY`.

This commit enables support for DTLS, i.e. TLS over datagram transport protocols like UDP. While support for DTLS is absent in CPython, it is worth supporting it in MicroPython because it is the basis of the ubiquitous CoAP protocol, used in many IoT projects. To select DTLS, a new set of "protocols" are added to SSLContext: - ssl.PROTOCOL_DTLS_CLIENT - ssl.PROTOCOL_DTLS_SERVER If one of these is set, the library assumes that the underlying socket is a datagram-like socket (i.e. UDP or similar). Our own timer callbacks are implemented because the out of the box implementation relies on `gettimeofday()`. This new DTLS feature is enabled on all ports that use mbedTLS. This commit is an update to a previous PR adafruit#10062. Addresses issue adafruit#5270 which requested DTLS support. Signed-off-by: Keenan Johnson <[email protected]>
