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 function-like macro naming that was missing in previous PRs: up_savestate() and up_restorestate() which must be named arm_savestate() and arm_restorestate().
Impact
There should be no impact of this change (other that one step toward more consistent naming).

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.
Impact
There should be not impact of this change (other that one step toward more consistent naming).

* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
