Going through the Frame (Sub)types the "QOS Data" being called "QOS"
scheme leads to a naming conflict for QOS_CFPOLL and QOS_CFACKPOLL
(if added). Rename QOS* to QOS_DATA* to avoid the conflict and
to also better match the standards name.
No functional changes intended.

Enabling other driver code found that the bssid in
struct ieee80211_bss_conf is not an array but expected to be
a const pointer (const, != NULL checks).
Adjust accordingly in the header and in the LinuxKPI compat code.
There initialization now needs to be a static array always present
as we need a value before we will have a BSS (node in scan_to_auth)
as the mac80211 driver (*handlers) are expecting the pointer to be
not NULL (copying without checks).
This is a pre-req to enable d3 (CONFIG_PM[_SLEEP]) in the future.

This is a joint work with manu.
- fixed conditions in do_i2c_transfer and i2c_transfer as linux_i2cbb
does not set adapter->algo->master_xfer but does set
adapter->algo_data;
- fixed parent bus specification for linux_i2cbb driver module;
- actually implemented iicbb_transfer method;
- added iicbb_pre_xfer and iicbb_post_xfer methods;
- removed unnecessary and harmful delays (and other extra logic) from
iicbb methods as iicbb driver already has them;
- added setting of iicbb speed based on algo_data->udelay, so that iicbb
uses correct delays;

RB_ROTATE_LEFT (and it symmetric twin) modify the rb-tree, adjusting
pointers so that what started as a proper tree ends up a proper
tree. When two consecutive rotations move the same node up the tree,
some of the pointers changed in the first rotation are immediately
changed again in the second - namely, the pointer from the rising node
to its new parent, and the pointer from that parent back to the rising
node. This change removes from RB_ROTATE macros the responsibility for
managing those two pointers, and leaves it to the code that calls for
rotations to fix up those pointers afterward. That drops a comparison
and a pair of assignments from every INSERT_COLOR or REMOVE_COLOR call
that ends in a double rotation.
A side-effect of this change is that the SWAP_CHILD macro must take as
a parameter a pointer to the node that is changing children, where it
is now computed from the old child. Since this macro is called in a
couple of places besides the RB_ROTATE macros, those calls are also
affected.

Rather than defining the same values in two places and having to do
conflict resulution on the name in LKPI, change the defines to an
enum in net80211. In addition to de-duplication this also gives us
value checks in certain cases.

In Linux this takes a refcount_t argument but in linuxkpi struct kref
uses an atomic_t for the refcount and code in drm directly uses this
function with a kref so use an atomic_t here.

o Assert that every protosw has pr_attach. Now this structure is
only for socket protocols declarations and nothing else.
o Merge struct pr_usrreqs into struct protosw. This was suggested
in 1996 by wollman@ (see 7b187005d1), and later reiterated
in 2006 by rwatson@ (see 6fbb9cf860).
o Make struct domain hold a variable sized array of protosw pointers.
For most protocols these pointers are initialized statically.
Those domains that may have loadable protocols have spacers. IPv4
and IPv6 have 8 spacers each (andre@ dff3237ee5).
o For inetsw and inet6sw leave a comment noting that many protosw
entries very likely are dead code.
o Refactor pf_proto_[un]register() into protosw_[un]register().
o Isolate pr_*_notsupp() methods into uipc_domain.c

Make most AST handlers dynamically registered. This allows to have
subsystem-specific handler source located in the subsystem files,
instead of making subr_trap.c aware of it. For instance, signal
delivery code on return to userspace is now moved to kern_sig.c.
Also, it allows to have some handlers designated as the cleanup (kclear)
type, which are called both at AST and on thread/process exit. For
instance, ast(), exit1(), and NFS server no longer need to be aware
about UFS softdep processing.
The dynamic registration also allows third-party modules to register AST
handlers if needed. There is one caveat with loadable modules: the
code does not make any effort to ensure that the module is not unloaded
before all threads processed through AST handler in it. In fact, this
is already present behavior for hwpmc.ko and ufs.ko. I do not think it
is worth the efforts and the runtime overhead to try to fix it.

While working on new and updates to drivers more structs, fields,
functions, .. were found, had to be shuffled around, ..
Some of these are (so far still dummy) functions or not properly
typed fields. The IEEE80211_HE_ constants are all still dummy.
This was msotly as a start to make new (out-of-tree) things compile.
