This fixes the problem that an assertion in sim build aborted NuttX
even when the assertion was generated from userspace (in which case
simpy the task needs to exit). This required moving the relevant code
into the sim blob.
Summary:
- In the previous implementation, signal handling for SMP was done
in a critical section that is not correct
- This commit fixes this issue
Impact:
- signal handling for SMP
Testing:
- Tested with ostest

Summary:
- During repeating ostest with sabre-6quad:smp (QEMU),
I noticed that pthread_rwlock_test sometimes stops
- Finally, I found that nxtask_exit() released a critical
section too early before context switching which resulted in
selecting inappropriate TCB
- This commit fixes this issue by moving nxsched_resume_scheduler()
from nxtask_exit() to up_exit() and also removing
spin_setbit() and spin_clrbit() from nxtask_exit()
because the caller holds a critical section
- To be consistent with non-SMP cases, the above changes
were done for all CPU architectures
Impact:
- This commit affects all CPU architectures regardless of SMP
Testing:
- Tested with ostest with the following configs
- sabre-6quad:smp (QEMU, dev board), sabre-6quad:nsh (QEMU)
- spresense:wifi_smp
- sim:smp, sim:ostest
- maix-bit:smp (QEMU)
- esp32-devkitc:smp (QEMU)
- lc823450-xgevk:rndis

Summary
- This commit fixes interrupt handling for SMP
- The following are the changes
- Introduce up_copyfullstate.c
- Add enter_critical_section() to up_exit()
- Add a critical section to up_schedule_sigaction()
- Introduce pseudo timer thread to send periodic events
- UART and interval timer are now handled in the pause handler
- Apply the same SMP related code as other CPU architectures
- However, signal handling and context switching are not changed
- Also enable debug features and some tools in smp/defconfig
Imact
- SMP only
Testing
- Tested with sim:smp on ubuntu18.04 x86_64
- Tested with hello, taskset, smp, ostest
