libcopybit: protect all c2d copybit API's

- Each client API exposed by the copybit C2D needs
  to be protected.
- Add protection for clear_copybit and blit_copybit
- This is needed as clear_copybit was overriding the
  mapped gpuaddr while copybitwaitthread was waiting
  for transaction to finish and unmap
- After waitforTimestamp, the new addresses were
  unmapped leading to GPU Page fault
