Mpersify decoder of struct xfs_dqstats

Browse Source 
* xfs_quota_stat.h: New file.
* fetch_struct_xfs_quotastat.c: Likewise.
* Makefile.am (strace_SOURCES): Add them.
* quota.c: Include xfs_quota_stat.h
(struct fs_qfilestat, struct xfs_dqstats): Moved to xfs_quota_stat.h.
(decode_cmd_data) <case Q_XGETQSTAT>: Use fetch_struct_quotastat.
