* This patch adds rebuildEM tool support to work with compressed files.
* This patch increases a version of the file header.
Note: Default version of the `rebuildEM` tool was using very old API,
those functions are not present currently. So `rebuildEM` will not work with
files created without compression, because we cannot deduce some info which are
needed to create column extent.
The ChunkManager class was getting an IDBFileSystem instance in
a different way than seemingly everything else. Added code
to allow it to get an SMFileSystem if cloud storage is specified.
I reformulate the messages.
Changed version in preprocessor conditions to avoid compilation
warnings in Debian 9.
Disabled sign-compare check for generated files in DML/DDL.
Fixed pragmas that disables compilation checks.
DDLProc now returns an error if it couldn't cwd.
Use either auto_ptr or unique_ptr depending on GCC version.
* DML writes for multi-block dictionary (blob) now works
* PrimProc fixed so that the first block in multi-block is read
correctly
* Performance optimisation (removed string copy into stack) for new
dictionary entries
