1.The nice value shall in the range [-{NZERO},{NZERO} -1]
2.Lower nice value shall cause more favorable scheduling

I not two problems in handling of the return error values in PR #3858:
1. In KERNEL mode, the error return value of _SEM_WAIT() will be a negated errno value; in all other modes, it will be -1 (ERROR) with the errno variable set. This must be handled in the test of the returned value: Don't compare with -1; rather check if < 0
2. Also, conversion of the returned value to a negated errno value must be handled differently. This is handled by replacing -get_errno() with the macro _ERRVAL(ret)
This effects only error handling (it fixes it) and no other impacts are expected.
It's better to save one argument by returning pid directly.
This change also follow the convention of task_create.
BTW, it is reasonable to adjust the function prototype a
little bit from both implementation and consistency since
task_spawn is NuttX specific API.

OS functions in syscall.csv are ordered alphabetically. However, two recently added functions are not in the correct location. This PR simply corrects that ordering.
The ordering of one entry was also corrected in libs/libc/libc.csv. Same issue.
This change is only cosmetic.

Drop to user-space in kernel/protected build with up_pthread_exit,
now all pthread_cleanup functions executed in user mode.
* A new syscall SYS_pthread_exit added
* A new tcb flag TCB_FLAG_CANCEL_DOING added
* up_pthread_exit implemented for riscv/arm arch

Pros:
* Reduce code differences
* Smaller allocations for !CONFIG_ARCH_USE_MODULE_TEXT
Cons:
* Likely to use more memory for !CONFIG_ARCH_USE_MODULE_TEXT in total
Tested with:
* sim:module on macOS
* esp32-devkit:nsh + CONFIG_MODULE on qemu
* lm3s6965-ek:qemu-protected + CONFIG_EXAMPLES_SOTEST on qemu
arch: Allocate the space from the beginning in up_stack_frame
and modify the affected portion:
1.Correct the stack dump and check
2.Allocate tls_info_s by up_stack_frame too
3.Move the stack fork allocation from arch to sched
