Rework the xxxVERBOSE option to share the common module-hook-based
verbose mechanism with MIIVERBOSE.  This reduces some duplicated code
and allows us to once again permit auto-unload of MIIVERBOSE.

Change details:
* Update dev/devlist2h.awk to accomodate miidevs, including generation
  of MII_STR_oui_model definitions and use of oui and model rather than
  vendor and product.  This also changes the compressed data in the
  xxxdevs_data.h files to uint32_t (since mii oui's are up to 6 hex
  digits long)
* Update a couple of phy drivers to use new calls to get verbose data
* Regen all of the xxxdevs{,_data}.h files (separate commit, coming
  very soon)
* Update mii/mii_verbose.[ch] and mii/mii_physubr.c to use the various
  DEV_VERBOSE_xxx macros
* Update the pci, usb, and hdaudio code as needed, to #include the
  xxxdevs.h files (in order to get the proper printf format strings)
* Since dev/dev_verbose.c now uses non-literal printf format strings,
  (to deal with the vendor/product vs oui/model issue), we need to
  make sure it gets compiled with -Wno-error=format-nonliteral, even
  in userland's libpci and librumpdev!
* Bump kernel version for the change in module interfaces

Welcome to 9.99.86!

XXX It might be useful in the future to extend the MII_STR_oui_model
XXX definitions to PCI as well (and perhaps USB and HDAUDIO).  This
XXX would allow for a single centralized location for the products'
XXX descriptions, rather than being dispersed among individual
XXX drivers' xxx_match tables.

Don't set DVF_DETACH_SHUTDOWN.  The MII layer wants to manage the lifecycle
of the PHY devices, and if a NIC driver chooses not to detach its PHYs
at shutdown, that's the driver's business.

PR kern/55121.

Define and implement a locking protocol for the ifmedia / mii layers:
- MP-safe drivers provide a mutex to ifmedia that is used to serialize
  access to media-related structures / hardware regsiters.  Converted
  drivers use the new ifmedia_init_with_lock() function for this.  The
  new name is provided to ease the transition.
- Un-converted drivers continue to call ifmedia_init(), which will supply
  a compatibility lock to be used instead.  Several media-related entry
  points must be aware of this compatibility lock, and are able to acquire
  it recursively a limited number of times, if needed.  This is a SPIN
  mutex with priority IPL_NET.
- This same lock is used to serialize access to PHY registers and other
  MII-related data structures.

The PHY drivers are modified to acquire and release the lock, as needed,
and assert the lock is held as a diagnostic aid.

The "usbnet" framework has had an overhaul of its internal locking
protocols to fit in with the media / mii changes, and the drivers adapted.

USB wifi drivers have been changed to provide their own adaptive mutex
to the ifmedia later via a new ieee80211_media_init_with_lock() function.
This is required because the USB drivers need an adaptive mutex.

Besised "usbnet", a few other drivers are converted: vmx, wm, ixgbe / ixv.

mcx also now calls ifmedia_init_with_lock() because it needs to also use
an adaptive mutex.  The mcx driver still needs to be fully converted to
NET_MPSAFE.

- Simplify sc->mii_anegticks setting. Same as FreeBSD.

   Don't set the default value not in the attach function. Instead, set the
  default value (MII_ANEGTICKS) first in the beginning of the
  mii_phy_add_media(). The function already has the code to change the value to
  MII_ANEGTICKS_GIGE if it's gigabit capable.

- Remove extra pmf_device_register() call. It's done in mii_phy_add_media().
