[PATCH 1/2] quota: Move function-macros from quota.h to quotaops.h

[Jan Kara <jack@suse.cz>]

Move declarations of some macros, which should be in fact functions
to quotaops.h. This way they can be later converted to inline functions
because we can now use declarations from quota.h. Also add necessary
includes of quotaops.h to a few files.
