profilesafe: Collect copies in single *.pack file

Enhanced helper classes for BackupFileHelper to
allow writing a stack of rescued last valid
configuration files to a single file package.
Added configuration values for enabling this and
defining the number of entries, added max entry
limitation. Using FileSize and CRC32 now to dectect
if config file did change. To make this work I added
sorting to writing the configuration so that with no
change the same configuration file is written.
Use std::vector for better mem performance for sorting,
defined static const for buffer size of manipulation,
prepare inflate/deflate usages. Fixes to setPos, warnings
