When we are asked for vfsv0 quota format and the file is in vfsv1
format (or vice versa), refuse to use the quota file. Also return
with error when we don't like the header of quota file.

So far the maximum quota space limit was 4TB. Apparently this isn't enough
for Lustre guys anymore. So implement new quota format which raises block
limits to 2^64 bytes. Also store number of inodes and inode limits in
64-bit variables as 2^32 files isn't that insanely high anymore.
The first version of the patch has been developed by Andrew Perepechko

Wrap long lines, remove assignments from conditions, rewrite two
overcomplicated for loops.

Quota subsystem has more and more files. It's time to create a dir for it.
