osdc/Striper: implemented a lightweight version of file_to_extents

The previous versions of file_to_extents resulted in numerous heap
allocations for maps, vectors, and strings -- in addition to using
a CPU inefficient oid name formater.

librbd doesn't require the use of object_t and it would be better to
avoid any heap allocations on the IO path for the common case.
