Fix uninitialized memory reference in mps_read_config_page. It was
referencing a field (params->hdr.Ext.ExtPageType) that would only be
set when reading an Extended config page. The symptom was that
MPSIO_READ_CFG_PAGE ioctls would randomly fail with
MPI2_IOCSTATUS_CONFIG_INVALID_PAGE errors. The solution is to
determine whether an extended or an ordinary config page is requested
by looking at the PageType field, which should be available regardless.
Similarly, mps_user_read_extcfg_header and mps_user_read_extcfg_page,
which call mps_read_config_page, had to be fixed to always set the
PageType field. They were implicitly assuming that
mps_read_config_page always operated on Extended pages.

with merge the functions but leave out the code to save/load the VFP
registers as that requires other changes to ensure the VFP is enabled
first.
This removes storing the old fpa registers. These were never fully
supported, and the only user of this code I can find have moved to newer
CPUs which use a VFP.
this menu consistent with Console->Repeat, Console->Font, Console->Screenmap
and many others which place the default choice at the top.
NOTE: SVN r249751 changed things so that these menus highlight the active
selection, so the idea that the default choice (now at top) "can be selected
immediately by hitting ENTER" is not possible unless the default choice is
the currently active setting (e.g., on first visit to the menu). However, it
is still warranted to have the default choice at the top of the menu.

dialog(1) API in dialog.subr responsible for retrieving menu-choice data
(for the --menu widget).
Add f_dialog_menuitem_store()/f_dialog_menuitem_fetch() for storing and
retrieving the menuitem (not the tag) from a --menu widget result.
The dialog --menu widget returns the `tag' from the tag/item pair of choices
for a menu list. Because the menu list is often local to the function that
is displaying it, the ability to dereference this into the item is not
possible unless you use a global. This changes things so the function (upon
successful return of dialog) dereferences the tag into the item and stores
it for later retrieval using these functions.
NOTE: Tags are dereferenced into items using f_dialog_menutag2item().

* Grab the reset lock first, so any subsequent interrupt, TX, RX work
will fail
* Then shut down interrupts
* Then wait for TX/RX to finish running
At this point no further work will be running, so it's safe to do the
reset path code.

The main problem here is that fast and driver RX diversity isn't actually
