    Make git revision more descriptive
    
    The previously introduced mechanism of generating
    a git revision was only using the abbreviated hash.
    That approach doesn't give a clue whether version
    1.8.18.2c99bf6 is newer or older than 1.8.18.7f8d374.
    
    The project uses tags, so `git describe` can be
    employed to produce an incremental revision number
    since the last tag. Version 1.8.18.13 is much more
    understandable and comparable. Howerver that doesn't
    answer the question "what codebase was used". To
    address that, the abbreviated hash should also be
    preserved. Hence, this commit introduces a new
    versioning scheme like `1.8.18.13.gee01aa5`.
    
    For git snapshots when git program is absent the
    version will be like `1.8.18.0.gsnapshot`.
    
    For cases when .git directory is missing (Release
    compilation?) the suffix part will be omitted
    completely yielding a version like `1.8.18`.
    
    The suffix generation has been moved to the added
    csv-revision script. The script is absolutely
    POSIX-ly correct and doesn't require XSI or any
    other POSIX extensions.
