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.

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.
Verified only by CI
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

Move sched/task/task/task_gettid.c to libs/libc/unistd/lib_gettid.c. gettid() is a dumb wrapper around getpid(). It is wasteful of resources to support TWO systme calls, one for getpid() and one for gettid(). Instead, move gettid() in the C library where it calls the single sysgtem call, getpid(). Much cleaner.
