From: Christoph Hellwig <hch at lst.de>
BugLink: https://bugs.launchpad.net/bugs/1950239
There is no point in splitting the fields like this in an purely
in-memory structure.

(backported from commit de7a866fd41b227b0aa6e9cbeb0dae221c12f542)
[cascardo: conflicts because of changed code, including:
new function xfs_qm_id_for_quotatype on xfs_dquot.c
XFS_QMOPT_DQALLOC flag turned into a bool
xfs_qm_quotacheck_dqadjust losing the id parameter
support for FSSETXATTR, introducing xfs_fill_fsxattr
new v5 bulkstat structure
]
[cascardo: looked for missing conversions of xfs_get_projid]
