Bug description:
CONFIG_SMP=y
Suppose we have 2 cores in SMP, here is the ps return:
PID GROUP CPU PRI POLICY TYPE NPX STATE STACK USED FILLED COMMAND
0 0 0 0 FIFO Kthread N-- Assigned 004076 000748 18.3% CPU0 IDLE
1 0 1 0 FIFO Kthread N-- Running 004096 000540 13.1% CPU1 IDLE
nsh> kill -4 0
or:
nsh> kill -4 1
system blocked.
Reason:
In func xx_sigdeliver() restore stage, when saved_irqcount == 0, that means
rtcb NOT in critical_section before switch to xx_sigdeliver(), then we need
reset the critical_section state before swith back.
Fix:
Add condition to cover saved_irqcount == 0.

since there are situation which send singal to idle thread already,
CONFIG_SCHED_CHILD_STATUS=y
CONFIG_SCHED_HAVE_PARENT=y
Signo SIGCHLD will send to parent group, when child exit

It is unnecessary to protect pollnotify since the wakeup
source comes from idle thread

Since we do not have the Nagle's algorithm,
the TCP_NODELAY socket option is enabled by default.

let's call either nx_dup/nx_dup2 or file_dup/file_dup2
instead just like other fs api: xxx->nx_xxx->file_xxx

the argument passed to file_dup2 doesn't always come from task file list
so it doesn't make sense to hold the file list lock and then it is better
to do the protection in the new function files_dupfd2
