## Summary Add POSIX‑compliant default signal handling for SIGURG: 1. Introduce CONFIG_SIG_SIGURG_ACTION Kconfig option to enable default SIGURG behavior. 2. Register nxsig_null_action (ignore) as the default action for SIGURG when the option is selected, aligning with the POSIX requirement that SIGURG be ignored by default. ## Impact 1. Makes NuttX signal behavior conform to the POSIX standard for SIGURG. 2. Fixes the failing test case /tset/ANSI.os/signal/signal_X/T.signal_X which expects SIGURG to be ignored by default. 3. Maintains backward compatibility: existing applications that explicitly handle SIGURG are unaffected, and the feature is optional (default n). ## Testing Verified that the /tset/ANSI.os/signal/signal_X/T.signal_X test case now passes. -- This is an automated message from the Apache Git Service.
