LU-4664 libcfs: allow file/func/line passed to CDEBUG()

LU-4664 libcfs: allow file/func/line passed to CDEBUG()

Allow the file, function, and line number to be passed to CDEBUG()
messages so that they are not duplicated in helper functions that
may be called from multiple places.

This patch is largely a no-op in terms of code, with the exception
of one call in osc_extent_sanity_check0() to OSC_EXTENT_DUMP() that
is changed to OSC_EXTENT_DUMP_WITH_LOC().
