Now that OBJTOP is assumed to be proper, it needs to be overridden for
the bootstrap-tools phase to ensure it is not kept as the top-level
OBJTOP. Otherwise the libraries were not found during the
bootstrap-tools phase.

When this option is set, the NFS server uses the list of groups
acquired via getgrouplist(3) for the uid instead of the list of
groups in the RPC request. This can be used to avoid the 16 gid
limit for the group list in the RPC request.

option that will be added to the nfsuserd daemon in a future
commit. It modifies the cache used by NFSv4 for name<-->id
translation (both username/uid and group/gid) to support this.
When "-manage-gids" is set, the server looks up each uid
for the RPC and uses the list of groups cached in the server
instead of the list of groups provided in the RPC request.
The cached group list is acquired for the cache by the nfsuserd
daemon via getgrouplist(3).
This avoids the 16 groups limit for the list in the RPC request.
Since the cache is now used for every RPC when "-manage-gids"
is enabled, the code also modifies the cache to use a separate
mutex for each hash list instead of a single global mutex.

tested on the Broadwell-Xeon with a hacked up version of pmcstudy -T. I still need
to circle back and add in to pmcstudy all the new tests from the Broadwell Vtune
guide (for the hacked up version I just made it so I could run the -T option). The
Skylake CPU is not yet available (even though Intel is advertising it .. imagine that).
The Skylake PMC's will need to be tested once we can get a sample skylake CPU :-)

- add new TEX class for WT cacheable memory
- export new TEX class to kernel as VM_MEMATTR_WT attribute
- add new aliases VM_MEMATTR_WRITE_COMBINING and
VM_MEMATTR_WRITE_BACK, it's used in DRM code
Note:
Only Cortex A8 supports WT caching in HW. On rest of Cortex CPUs,
WT requests is treated as uncacheable.

The synth programming here requires the real centre frequency,
which for HT20 channels is the normal channel, but HT40 is
/not/ the primary channel. Everything else was using 'freq',
which is the correct centre frequency, but the hornet config
was using 'ichan' to do the lookup which was also the primary
channel.
So, modify the HAL call that does the mapping to take a frequency
in MHz and return the channel number.

Actual changes:
Add "rt_chain" field to permit rte grouping while doing batched delete

Add "rti_filter" / "rti_filterdata" / "rti_spare" fields to rt_addrinfo

Convert all rt_expunge() customers to new rt_addinfo-based api and eliminate

on every allocation and fully releases them on every free. These
are not trivial costs: it starts by zeroing a large structure then
initializes a mutex, a lock manager lock, an rw lock, four lists,
and six pointers. And looking at vfs.vnodes_created, these operations
are being done millions of times an hour on a busy machine.
As a performance optimization, this code update uses the uma_init
and uma_fini routines to do these initializations and cleanups only
as the vnodes enter and leave the vnode_zone. With this change the
initializations are only done kern.maxvnodes times at system startup
and then only rarely again. The frees are done only if the vnode_zone
shrinks which never happens in practice. For those curious about the
avoided work, look at the vnode_init() and vnode_fini() functions in
kern/vfs_subr.c to see the code that has been removed from the main
vnode allocation/free path.

the name of a filesystem when setting it as the first parameter to the
getnewvnode() function. Most filesystems call getnewvnode from just one
place so can use a literal string as the first parameter. However, NFS
calls getnewvnode from two places, so we create a global constant string
that can be used by the two instances. This change also collapses two
instances of getnewvnode() in the UFS filesystem to a single call.
