Modified Files:
        src/sys/ufs/lfs: lfs_accessors.h lfs_segment.c lfs_subr.c lfs_vfsops.c

Log Message:
Handle two causes of the panic "lfs_ifile: looping".  Repurpose the lfs_iflock
to be locked with RW_WRITER while the segment lock is held, preventing
updates to the Ifile while its blocks are being gathered; and allow more
iterations than 10 before panicking, since we might need to rewrite the
entire segment table one block per iteration.  Issue uncovered in the course
of PR kern/60746.
