These functions convert relative addresses to absolute addresses\r
in CALL instructions to increase the compression ratio.\r
\r
  In:\r
    data     - data buffer\r
    size     - size of data\r
    ip       - current virtual Instruction Pinter (IP) value\r
    state    - state variable for x86 converter\r
    encoding - 0 (for decoding), 1 (for encoding)\r
\r
  Out:\r
    state    - state variable for x86 converter\r
\r
  Returns:\r
    The number of processed bytes. If you call these functions with multiple calls,\r
    you must start next call with first byte after block of processed bytes.\r

\r
  size must be >= Alignment + LookAhead, if it's not last block.\r
  If (size < Alignment + LookAhead), converter returns 0.\r

  Example:\r
\r
    UInt32 ip = 0;\r
    for ()\r
    {\r
      ; size must be >= Alignment + LookAhead, if it's not last block\r

      data += processed;\r
