* Name: signal_handler
*
* Description:
* This function is the user-space, signal handler trampoline function. It
* is called from up_signal_handler() in user-mode.
*
* Inputs:
* sighand - The address user-space signal handling function
* signo, info, and ucontext - Standard arguments to be passed to the
* signal handling function.
*
* Return:
* None. This function does not return in the normal sense. It returns
* via signal_handler_return (see include/nuttx/arch.h)
*
