/****************************************************************
Summary:
Lock BDBG module from multiple accesses.

Description:
DBG requires that BDBG_P_Lock be implemented per OS.
BDBG_P_Lock must work in both task and isr modes.
Therefore, BDBG_P_Lock cannot be implemented by calling BKNI_AcquireMutex or BKNI_EnterCriticalSection which only work in task mode.

Your OS's implementation of BDBG_P_Lock will likely look similar to your OS's implementation of BKNI_EnterCriticalSection.
For example, in linux user mode, BDBG_P_Lock acquries a pthread mutex.
For another example, in linux kernel mode, BDBG_P_Lock acquires a spin lock.
