	o /dev/dtrace/helper device (needed for USDT probes)

	The work done by me was:
	Sponsored by:   The FreeBSD Foundation

plus a few netbsd-specific tweaks from me.

22c82d5b7b - Add processing for c++ references. 
- Make sure we load the DIE that contains the types of array elements so
  we can resolve them later.

f2e47b4038 Merge r274564 from FreeBSD: 
Fix a couple of bugs around the handling of structs and unions of size zero.
These would cause ctfconvert(1) to return an error when attempting to
resolve valid C types.

a37e72fe0d Let MKCTF alone control whether we build libctf. 
If MKDTRACE=yes MKCTF=no makes no sense, we can express that
somewhere else, not as a confusing set lists error at the end -- as
far as I know, there's no way to express MKDTRACE *or* MKCTF as a
condition for set list entries.

486516affa Clang 3.7 and newer provide the array size via DW_AT_count, not via 
DW_AT_upper_bound. Recognize the former as well as the latter.

604231c4f0 - don't barf if the object does not have DWARF debug data. 
- bump size of types to 1K to avoid string overflow
(both are needed for the new elftoolchain).

e9ae0934d6 dmu_objset_rename is an alias for dsl_dataset_rename, but differs in 
constness of the first argument. Newer clang checks for this and
prohibits it, so just be consistent by constifying the latter.
