function parameters, the card has to be in transfer state. If it is in
the idle state, the commands are ignored. This caused us not to set
the proper parameters that we later assume to be present, leading to
downstream failures of the card / interface as our state machine
mismatches the card's.

into namecache, to avoid cache trashing when doing large operations.
E.g., tar archive extraction is not usually followed by access to many
of the files created.
Right now, each VOP_LOOKUP() implementation explicitely knowns about
this quirk and tests for both MAKEENTRY flag presence and op != CREATE
to make the call to cache_enter(). Centralize the handling of the
quirk into VFS, by deciding to cache only by MAKEENTRY flag in VOP.
VFS now sets NOCACHE flag for CREATE namei() calls.
Note that the change in semantic is backward-compatible and could be
merged to the stable branch, and is compatible with non-changed
third-party filesystems which correctly handle MAKEENTRY.

it's not just 11b/11g.
The following was happening, and it's quite .. annoyingly grr-y.
* create vap, setup wpa_supplicant with no bgscanning, etc - there's
no call to ieee80211_media_change, so vap->iv_des_mode is
IEEE80211_MODE_AUTO;
* do ifconfig wlan0 scan - same thing, media_change doesn't get called,
iv_des_mode stays as auto.
* But then, run wpa_cli and do 'scan' - it'll do a media change.
* if you're on 11ng, vap->iv_des_mode gets changed to IEEE80211_MODE_11NG
* Then makescanlist() is called. There's a block of code that gets
called if iv_des_mode != IEEE80211_MODE_AUTO, and it does this:
if (vap->iv_des_mode != IEEE80211_MODE_11G ||
mode != IEEE80211_MODE_11B)
continue;
mode = IEEE80211_MODE_11G; /* upgrade */
* .. now, iv_des_mode is not IEEE80211_MODE_11G, so it always runs
'continue'
* .. and thus the scan list stays empty and no further channel
scans occur. Ever.(1)
If you then disassociate and try associating to something, your
scan table has likely been purged / aged out and you'll never
see anything in the scan list.
(1) You need to do 'ifconfig wlan0 mode auto' or just destroy/re-create
the VAP to get working wireless again.
Tested:
* iwn(4) - intel 5300 wifi; STA mode; using wpa_supplicant; bgscan
enabled -and- wpa_supplicant scanning.
Thanks to:
* Everyone who kept poking me about this and wondering why the hell
their wifi would eventually stop seeing scan lists. Grr.
I eventually snapped this evening and dug back into this code.
new dpv(3) wrapper to dialog(3) dialog_gauge(). The dpv(3) library provides
a more flexible and refined interface similar to dialog_mixedgauge() however
is implemented atop the more generalized dialog_gauge() for portability.
Noticeable improvements in bsdinstall's distextract will be a status line
showing data rate information (with support for localeconv(3) to format
numbers according to $LANG or $LC_ALL conversion information), i18n support,
improved auto-sizing of gauge widget, a ``wheel barrow'' to keep the user
informed that things are moving (even if status/progress has not changed),
improved color support (mini-progress bars use the same color, if enabled,
as the main gauge bar), and several other improvements (some not visible).
dpv stands for "dialog progress view" (dpv was introduced in SVN r274116).

Summary:
This change converts NanoBSD into a two-script bundle.
- defaults.sh contains all non-CLI code. Most NanoBSD code is moved into
this file.
- nanobsd.sh now consists just of a command line interface that calls into
functions in defaults.sh.
Test Plan: Run NanoBSD using a previously-working configuration.

The C11 standard introduced a set of macros (CMPLX, CMPLXF, CMPLXL) that
can be used to construct complex numbers from a pair of real and
imaginary numbers. Unfortunately, they require some compiler support,
which is why we only define them for Clang and GCC>=4.7.
The cpack() function in libm performs the same task as CMPLX(), but
cannot be used to generate compile-time constants. This means that all
invocations of cpack() can safely be replaced by C11's CMPLX(). To keep
the code building with GCC 4.2, provide copies of CMPLX() that can at
least be used to generate run-time complex numbers.
This makes it easier to build some of the functions outside of libm.
