uses the built-in based f_replaceall() which out-performs forking to
awk(1)). This should also improve readability slightly.
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().

PTP Tang, "Table-driven implementation of the Expm1 function
in IEEE floating-point arithmetic," ACM Trans. Math. Soft., 18,
211-222 (1992).
Over the last 18-24 months, the code has under gone significant
optimization and testing.

* 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
configured; I need to figure out why that is. That said, this makes
the single-antenna connected AR9285 and AR2427 (AR9285 w/ no 11n) work
correctly.

I initially thought wchar_t was locale independent, but this seems to be
only the case on Linux. This means that we cannot depend on the *wc*()
routines to implement *c16*() and *c32*(). Instead, use the Citrus
libiconv that is part of libc.
I'll see if there is anything I can do to make the existing functions
somewhat useful in case the system is built without libiconv in the
nearby future. If not, I'll simply remove the broken implementations.
