Subject: stdio_names: Ensure MAX_NAMES is defined before use, don't use 3 directly
X-Git-Tag: v2025.01-rc5-pxa1908~4411

stdio_names: Ensure MAX_NAMES is defined before use, don't use 3 directly

With tighter build flags the fact that <stdio_dev.h> doesn't have a
reference back to MAX_NAMES causes an error.  Include <stdio.h> here and
then in common/console.c use MAX_NAMES rather than 3 when working with
stdio_names.
