Add missing ENTRY() and RET() macros in C callable assembly language. At one time I though the that the ESP32 support the CALL0 ABI. I was mistaken so there may be a few more like this.

ESP32 core v2: Two changes (1) flushes the UART TX buffer in the esp32 serial shutdown routine. The ROM bootloader does not flush the FIFO before handing over to user code, so some of this output is not currently seen when the UART is reconfigured in early stages of startup. And changes the openocd config file's default flash voltage from 1.8V to 3.3V. This is not necessary right now, but may save some hard-to-debug moments down the track (3.3V-only flash running at 1.8V often half-works and does weird things...)

Remove minnsh configurations and support logic: up_getc() and lowinstream.
...
This was an interesting exercise to see just how small you could get NuttX, but otherwise it was not useful: (1) the NSH code violated the OS interface layer by callup up_getc and up_putc directly, and (2) while waiting for character input, NSH would call up_getc() which would hog all of the CPU. NOt a reasonably solution other than as a proof of concept.

SAMV7: MCAN: Prevent Interrupt-Flooding of ACKE when not connected to CAN-BUS. An Acknowledge-Error will occur every time no other CAN Node acknowledges the message sent. This will also occur if the device is not connected to the can-bus. The CAN-Standard declares, that the Chip has to retry a given message as long as it is not sent successfully (or it is not cancelled by the application). Every time the chip tries to resend the message an Acknowledge-Error-Interrupt is generated. At high baud rates this can lead in extremely high CPU load just for handling the interrupts (and possibly the error handling in the application). To prevent this Interrupt-Flooding we disable the ACKE once it is seen as long we didn't transfer at least one message successfully.

I was wrong - the original commit was correct. Assume a write op on the last word: address of 0xxxxxfe and count of 2. It is a valid operation and address+count is == STM32_FLASH_SIZE - so that is OK
