anupamg 0137495706 DCE-KMD: Make dce-client-ipc.c core file
- This change will remove linux nuances from dce-client-ipc.c
  file and make it a core DCE-KMD file agnostic to OS.

- To do that, dce-client-ipc module will repalce linux specific
  nuances for work queue related functionality with
  dce-os-work module.

- Further to support existing dce_client_ipc asyn callback function
  we need to make worker queue more generic by allowing clients
  to pass any data of their choice as data param to the
  callback function.

- Also take this opportunity to make following functions static:
    - dce_resume_work_fn()
    - dce_bootstrap_work_fn()
