JCTVC-P0041: Signalling and decoding of POC (Several macros)

The following macros describe the code each contains:

  1. POC_RESET_IDC_SIGNALLING - signalling of POC-related syntax elements
  2. POC_RESET_IDC_ENCODER - support for POC reset at encoder
  3. POC_RESET_IDC_DECODER - support for POC reset at decoder

In addition two bugfixes, under macros ALIGN_IRAP_BUGFIX and UNAVAILABLE_PIC_BUGFIX are also submitted.
