MCOL-4566: Extend CompressedDBFileHeader struct with new fields.

Browse Source 
* This patch extends CompressedDBFileHeader struct with new fields:
  `fColumWidth`, `fColDataType`, which are necessary to rebuild extent map
  from the given file. Note: new fields do not change the memory
  layout of the struct, because the size is calculated as
  max(sizeof(CompressedDBFileHeader), HDR_BUF_LEN)).

* This patch changes API of some functions, by adding new function
  argument `colDataType` when needed, to be able to call `initHdr`
  function with colDataType value.
