Updates to indirect blocks of spacemaps can contribute significantly to
write inflation. Therefore we want to reduce the indirect block size of
spacemaps from 128K to 16K.
Porting notes:
* Refactored to allow the dmu_object_alloc(), dmu_object_alloc_ibs()
and dmu_object_alloc_dnsize() functions to use a common shared
dmu_object_alloc_impl() function.
