xfs: stop passing opaque handles to xfs_log.c routines
Currenly we pass opaque xfs_log_ticket_t handles instead of struct xlog_ticket pointers, and void pointers instead of struct xlog_in_core pointers to various log manager functions. Instead pass properly typed pointers after adding forward declarations for them to xfs_log.h, and adjust the touched function prototypes to the standard XFS style while at it.
