CURRENT_REGS may change during assert handling, so pass
in the 'regs' parameter at the entry point of _assert.

The current implementation requires the use of enter_critical_section, so the source code needs to be moved to kernel space

This is preparation for flushing streams from user space, like it should
be done.
- Move tg_streamlist (group, kernel space) ->
ta_streamlist (TLS, user space)
- Access stream list via tg_info in kernel
- Access stream list via TLS in user space
- Remove / rename nxsched_get_streams -> lib_getstreams
- Remove system call for nxsched_get_streams
I had a link problem regarding prctl while CONFIG_TASK_NAME_SIZE was
defined 0 and building in protected mode. Turns out in monolithic
build prctl is present no matter what CONFIG_TASK_NAME_SIZE, but in
protected mode build its only present if CONFIG_TASK_NAME_SIZE > 0.
So, bring protected mode build in sync with the monolithic one.

Deleting a task from another task's context will not do, so shut
this gate down for BUILD_KERNEL. In this case if a task wants another
task to terminate, it must ask the other task to politely kill itself.
Note: kthreads still need this, also, the kernel can delete a task
without asking.
Now that the environment strings are stored as an array of strings,
they can be passed from the application via char **environ, which
is really defined as a function call to get_environ_ptr().
This works as is for flat build, but protected mode and kernel mode
require a call gate, which is added here.
and implement all status related change function. the individual
file system change will provide in other upcoming patchset.

This reverts commit cc514d7791dae0808124249ff545d9dda39b24b7.
* It introduced a regression.
https://github.com/apache/incubator-nuttx/issues/3868
* It seems conceptually wrong to have per-process data in
the main thread's stack.
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.

Fix compilation when CONFIG_DEV_PIPE_SIZE > 0 && CONFIG_DEV_FIFO_SIZE == 0
In this case the nx_mkfifo doesn't exist.

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
