While not too late rename if_get_counter_compat() to if_get_counter_default().
The compat counters will go away, but the function will remain in its place,
and in all places where it is going to be called.

Fix an assert to tolerate spare parents with more than 2 children.

This can occur if a spare is being spared, which would yield three
children: the original pool drive, the previous spare, and the spare
that is replacing it.

zfs_setprop_error(): Handle errno value E2BIG.

This errno value is emitted by dsl_props_set_check() in
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/dsl_prop.c, and
is used to mean that the property value is too long.  For the record,
the maximum length is ZAP_MAXVALUELEN, which is 8*1024 bytes.

Instead of claiming an unknown error (and abort()ing), provide
something more specific to the scenario involved.  As far as I
can tell, E2BIG is not emitted for any other scenario.

		This change modified the value returned by
		dsl_props_set_check(), so that it can distinguish between
		a name that's too long and a value that's too long, but
		libzfs was not updated accordingly.

Add a function to set if_get_counter method for an ifnet. To be used
in the drivers that are already converted to "Juniper drvapi". This
can be revisited in future.
Fix incremental builds involving non-root users with read-only source files.

Makefiles should not assume that source files can be overwritten.  This is the
common case for Perforce source trees.

This is a followup commit to r211243 in the same vein.

Accidentially, ng_ppp changes leaked out with r271770. The proper
commit message should have been:

In case if ng_ppp(4) runs only IPv4, with one link, w/o any
encryption and compression, set faster rcvhook method.

While not too late rename 'ifnet_counter' to 'ift_counter'. One of the
imporant moments that we discussed with Marcel and Anuranjan was that
a converted driver should return false for 'grep ifnet if_driver.c' :)

bpobj_iterate_impl(): Close a refcount leak iterating on a sublist.

If bpobj_space() returned non-zero here, the sublist would have been
left open, along with the bonus buffer hold it requires.  This call
does not invoke any calls to bpobj_close() itself.

This bug doesn't have any known vector, but was found on inspection.

- Use if_inc_counter() to increment various counters.
- Do not ever set a counter to a value. For those counters
  that we don't increment, but return directly from hardware
  create cases in if_get_counter() method.
