libc/stdio: in dtoa(), up_interrupt_context() is used in a debug assertion. up_interrupt_context() is not available in the user-mode phase of the PROTECTED or KERNEL build configurations. In those configurations, enabling libc floating point support and debug assertions will result in an undefined reference to up_interrupt_context().

reopen should return NULL when oflags is less than 0, not equal to 0.
...
Because negative value is returned on failure of lib_mode2offlags which converts the mode string into file open mode flag.

Fix sscanf character conversion (%c): do not add '\0' at the end as for strings, cause, for example, parsing one character will fill two bytes: character itself and zero one '\0' after it, so will overflow one byte variable argument and corrupt memory for variables allocated after it.

fs/vfs: Add new internal OS interface nx_read(). nx_read() is functionally equivalent to read() except that it does not modify the errno variable and it is not a cancellation point. Changed all references to read() in the OS to nx_read().

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.
