SMP: Fix a gap where we may try to make modifications to the task lists without being in a critical sections. That permits concurrent access to the tasks lists and many subtle problems. This fix just remains in the critical section throughout the operation (and possible until the task is restore in the event of a context switch). Makes a big difference in stability

Xtensa ESP32: Corrects a problem with dispatching to signal handlers: Cannot vector directly to the signal handling function as in other ABIs under the Xtensa Window ABI. In that case, we need to go through a tiny hook when performs the correct window call (call4) otherwise registers will be scrambled in the signal handler

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.
