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

All supported arch uses a push-down stack:
The stack grows toward lower addresses in memory. The stack pointer
register points to the lowest, valid working address (the "top" of
the stack). Items on the stack are referenced as positive(include zero)
word offsets from sp.
Which means that for stack in the [begin, begin + size):
1.The initial SP point to begin + size
2.push equals sub and then store
3.pop equals load and then add

Summary
The naming standard at https://cwiki.apache.org/confluence/display/NUTTX/Naming+FAQ requires that all MCU-private functions begin with the name of the architecture, not up_.
This PR addresses only these name changes for the ARM-private functions prototyped in arm_internal.h
This change to the files only modifies the name of called functions. nxstyle fixes were made for all core architecture files. However, there are well over 5000 additional complaints from MCU drivers and board logic that are unrelated to to this change but were affected by the name change. It is not humanly possible to fix all of these. I ask that this change be treated like other cosmetic changes that we have done which do not require full nxstyle compliance.
Impact
There should be not impact of this change (other that one step toward more consistent naming).

This PR addresses only these name changes for the up_*.S files.
The entire job required to be compatible with that Naming Convention will also require changing the naming of the up_() functions that are used only within arch/arm and board/arm.

Summary
The naming standard at https://cwiki.apache.org/confluence/display/NUTTX/Naming+FAQ requires that all MCU-private files begin with the name of the architecture, not up_.
This PR addresses only these name changes for the up_*.h files. There are only three, but almost 1680 files that include them:
up_arch.h
up_internal.h
up_vfork.h
The only change to the files is from including up_arch.h to arm_arch.h (for example).
The entire job required to be compatible with that Naming Convention will also require changing the naming of the up_() functions that are used only within arch/arm and board/arm.
