[libDCE] Add IPC 3.x Adapted code to Repository3.00.01.00

This patch adds libdce code to the repository.
LibDCE has been adapted to use the MmRpc layer
of IPC 3.x. This version of LibDCE is expected to
work on QNX.

Patchset 2 adds/modifies:
1. Removes Tiler 2D allocation/free for now.
2. Corrects memplugin_free() for Tiler 1D.
3. Modifies dce_test app to dump output till 30 frames.
4. Renamed dce.h to libdce.h.
5. Corrected header files across all files.
6. Build configuration for QNX
7. Removes build warnings.
8. Add README for Build instructions
9. Takes care of comments of Buddy and Pradeep.

Patchset 3 adds/modifies:
1. Reduced Stack usage of each function.
2. Add ptr check in memplugin and remove from libdce.
3. Add DCE_Assert macros.
4. Add DCE_error_status enum.
5. Comments Cleanup
6. Make some functions static.
7. process() cleanup including removing reply_buf.
8. Add else if (for codec_type == Encoder type)
9. Converted Macros to Inline functions.
10.Converted init and deinit to dce_init and dce_deinit functions.
11. Removed dce_init() and dce_deinit() declarations

Patchset 4 adds/modifies:
1. Assert Input function arguments.
2. Correct copyright year.
3. Correct memplugin_free for Shared memory.
4. Create dce_priv.h and move trace and assert macros to the header.
5. Redeclare mem_type enum and add mem_error_status enum in
   memplugin.h and make corresponding changes.
6. Add asserts in memplugin.

Intention of some of the changes above is to move towards
delinking Libdce and Memplugin.

Patchset 5:
1. Missed to add dce_priv.h file.

Patchset 6:
1. Take care Pradeep's comment.
