#137 ceil semaphore status

[Pharos Team]

Add a new syscall for the ceiling semaphore get status that determines if a thread is holding the semaphore (or not). This function could be useful for debugging.

struct SemCeilStatus
{
    /**
     * Flag indicating if the semaphore is being held
     */
    bool isUsed;

    /**
     * Thread id of the holder
     */
    ThreadId holder;
};

PharosSemCeilStatusR pharosSSemCeilStatus(SemCeilNumber number , ptrSemCeilStatus status);
