bio_resid to detect short reads. This assumption proved false and
file corruption was the result.

Since its clean target seprate rm's for things, use NOPATH_FILES as list
to collect things that need .NOPATH.
bsd.obj.mk will add CLEANFILES to NOPATH_FILES and do the deed if needed.

This change is a bit ugly, but so is the coupling between the i915
driver and syscons. It isn't worth developing a more elegant solution
only to support the legacy syscons console.
The hcreate(3) implementation and related functions we inherited
from NetBSD used to free() the key value, something that is not
supported by the standard implementation.
This would cause a segmentation fault when attempting to run
the examples from the opengroup and linux manpages. NetBSD
has added non-standard calls to provide the previous
behaviour but hdestroy is not very commonly used so at this
time it seems excessive to bring those to FreeBSD.
Bump the __FreeBSD_version as this is an ABI change.

If RSS is enabled, ixgbe(4) will query the RSS API for the types of hashes
which should be used. It'll then only enable hashes that are exposed via
the RSS layer.
This way it won't try to do things like enable UDP hashing if RSS explicitly
states that it isn't supported in lookups.
Tested:
* 82599EB ixgbe(4) NIC
A mix of fragmented and non-fragmented UDP in a single stream will end up
being hashed differently, resulting in out-of-order behaviour in the receive
path.
This was done in the linux e1000 driver in 2011.

by the stack.
Right now the stack isn't really setup for RSS with 4-tuple UDP hashing
for either IPv4 and IPv6.
The specifics:
* The UDP init path udp_init() and udplite_init() specify the hash as
2-tuple, so the PCBGROUPS code only tries a 2-tuple check;
* The PCBGROUPS and RSS code doesn't know about the UDP hash types
just yet, so they're never treated as valid hashes.
* For correctness, 4-tuple can't be enabled in the general case because
UDP datagrams can be more fragmented than IP datagrams may be.
Strictly speaking, TCP datagrams may also be fragmented and this could
cause issues with PCBGROUPS/RSS until the IP defragment path grows some
code to re-calculate the RSS hash.
I'll follow this commit up with awareness of the UDP 4-tuple for those
who wish to configure it, but for now it'll stay disabled.
No drivers (yet) know to use this function when RSS is enabled.
