xfs: Add xfs_log_rlimit.c
Add source files for xfs_log_rlimit.c The new file is used for log
size calculations and validation shared with userspace.
[dchinner: xfs_log_calc_max_attrsetm_res() does not modify the
tr_attrsetm reservation, just calculates the maximum. ]
[dchinner: rework loop in xfs_log_get_max_trans_res() ]
