argv is allocated from stack and then belong to userspace,
so task_info_s is a best location to hold this information.

Because idle task will call mm_malloc to create some task
and will take sem of mm. But if smp enable, the sem of mm may be
taken by other cpu, so idle may be block because take this sem and crash.

chips that have multiple separate heaps.
For now it's used to enable APIs to initialize the different heaps
during the start sequence but can be extended for other purposes that
manage those heaps.

Follow the POSIX description.
SIGTSTP should be sent when the Ctrl-Z characters is encountered, not SIGSTP.
Testing:
Built with hifive1-revb:nsh (CONFIG_SERIAL_TERMIOS=y, CONFIG_SIG_DEFAULT=y and CONFIG_TTY_SIGTSTP=y)
because nx_task_idle doesn't call sched_note_start. To avoid the
same error happen again in the furture, nx_task_idle is removed.

Revert a portion of eca7059785 that
causes compiler warnings about unused variables if nx_start() is not
initializing any of the user-mode heap, kernel-mode heap, or page
allocator:
init/nx_start.c: In function 'nx_start':
init/nx_start.c:552:14: warning: unused variable 'heap_size'
[-Wunused-variable]
size_t heap_size;
^~~~~~~~~
init/nx_start.c:551:17: warning: unused variable 'heap_start'
[-Wunused-variable]
FAR void *heap_start;
^~~~~~~~~~
See dev@nuttx.apache.org mailing list discussion "New unused variables
warning in nx_start()" starting 6 May 2020, archived here:
https://lists.apache.org/thread.html/r3900727e6a06f4445d6eb881d065119ba6647daab89600c3d45d1424%40%3Cdev.nuttx.apache.org%3E
sched/init/nx_start.c:
* If none of MM_KERNEL_USRHEAP_INIT, CONFIG_MM_KERNEL_HEAP, or
CONFIG_MM_PGALLOC are defined, the variables heap_start and
heap_size were declared but never used.
* This change reinstates wrapping the block with a preprocessor
conditional to prevent the variables being declared if they will
not be used. This preprocessor condition was removed in the
above-mentioned commit.
And remove syslog_init_e because all initialization is later now and we don't
distinguish the initialition phase anymore after ramlog don't need special
initialize.
it doesn't make sense that iob initialization is in up_initialize
but other memory components initialization is called in nx_start
