cc1c3629c5 MCOL-987 Add LZ4 compression. 
* Adds CompressInterfaceLZ4 which uses LZ4 API for compress/uncompress.
* Adds CMake machinery to search LZ4 on running host.
* All methods which use static data and do not modify any internal data - become `static`,
  so we can use them without creation of the specific object. This is possible, because
  the header specification has not been modified. We still use 2 sections in header, first
  one with file meta data, the second one with pointers for compressed chunks.
* Methods `compress`, `uncompress`, `maxCompressedSize`, `getUncompressedSize` - become
  pure virtual, so we can override them for the other compression algos.
* Adds method `getChunkMagicNumber`, so we can verify chunk magic number
  for each compression algo.
* Renames "s/IDBCompressInterface/CompressInterface/g" according to requirement.

025838629b MCOL-454 I_S.COLUMNSTORE_FILES multi-node 
I_S.COLUMNSTORE_FILES returned bad filenames and NULL file sizes when
there are multiple nodes in a ColumnStore cluster

It adds an extra message call to the WriteEngine to get the file size
for that file. The I_S function will figure out which WriteEngine to
communicate with and get the file size details from it.
