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

_assert is a kernel procedure, entered via system call to make the core
dump in privileged mode.
Running exit() from this context is not OK as it runs the registered
exit functions and flushes streams, which must not be done
from privileged mode as it is a security hole.
Thus, implement assert() into user space (again) and remove the exit()
call from the kernel procedure.
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.

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.
