Remove dead code and cleanup scoping in dmu_send.c

Browse Source 
This addresses a number of problems with dmu_send.c:

* bp_span is unused which makes clang complain
* dump_write conflicts with FreeBSD's existing core dump code
* range_alloc is private to the file and not declared in any headers
  causing clang to complain
