* 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.
