Fix logic error in gvinum's gv_set_sd_state()
With clang 4.0.0, I'm getting the following warnings:
sys/geom/vinum/geom_vinum_state.c:186:7: error: logical not is only

The logical not operator should obiously be called after masking.
Add direction argument to ipsec_setspidx_inpcb() function.
This function is used only by ipsec_getpolicybysock() to fill security
policy index selector for locally generated packets (that have INPCB).
The function incorrectly assumes that spidx is the same for both directions.
Fix this by using new direction argument to specify correct INPCB security
policy - sp_in or sp_out. There is no need to fill both policy indeces,
because they are overwritten for each packet.
This fixes security policy matching for outbound packets when user has
specified TCP/UDP ports in the security policy upperspec.

[net80211] Add initial VHT support routines.
This is a skeleton set based on ieee80211_ht.c. It implements some IE
parsing, some basic unfinished negotiation, and channel promotion/demotion.
However, by itself it's not enough to do VHT - notably, the actual
channel promotion for STA mode at least is done in ieee80211_ht.c as
part of htinfo_update_chw(). I was .. quite amused when I found that
out.
I'm checking this in so others can see progress rather than one huge
commit when VHT is "done" (which will likely be quite a while.)

Add a new sdhci interface method, get_card_present().
Many embedded SoC controllers that are (more or less) sdhci-compatible don't
implement card detect, and the related values in the PRESENT_STATE register
aren't useful. A bridge driver can now implement get_card_present() to read
a gpio pin or whatever else is necessary for that system.
The default implementation reads the CARD_PRESENT bit from the PRESENT_STATE
register, so existing drivers will keep working (or keep not-fully-working,
since many drivers right now can't detect card insert/remove).
Export __cxa_thread_atexit_impl as an alias for __cxa_thread_atexit.
libstdc++ before gcc r244057 expected that libc provided
__cxa_thread_atexit_impl, and libstdc++ implemented
__cxa_thread_atexit, by forwarding the calls to _impl. Mentioned gcc
revision checks for __cxa_thread_atexit in libc and does not provide
the symbol from libstdc++ if found.
This change helps older gcc, in particular, all released versions
which implement thread_local, by consolidating the implementation into
libc. For that versions, if configured with the current libc, the
__cxa_thread_atexit is exported from libstdc++ as a trivial wrapper
around libc::__cxa_thread_atexit_impl.
The __cxa_thread_atexit implementation is put into separate source
file to allow for static linking with older libstdc++.a.

Obviously, the masking needs to be done before the logical not
operation. Add parentheses to make it so.
sched_*(2) syscalls might be not available at runtime. Defining this
constant as zero directs POSIX-compliant code to call sysconf(3) to
detect the feature at runtime, and forces libc sysconf(3) to ask

[ifconfig] add initial VHT (802.11ac) configuration and channel support to ifconfig.
This is very preliminary and mostly enough for me (with other patches)
to work on VHT support.
It adds:
* VHT20, VHT40 and VHT80 regulatory/band awareness
* VHT20, VHT40 and VHT80 channel configuration / population
* Parses vht channel specifications (eg ifconfig wlan0 create wlandev athp0 wlanmode monitor channel 36:vht/80)
* Configuration of VHT, VHT40, VHT80, VHT80+80, VHT160 channel
width (IEEE80211_FVHT_VHT* flags in net80211)
TODO:
* No VHT80+80 or VHT160 channels yet - I don't yet have hardware, and I'm
not yet sure how to support/populate VHT80+80 channels.
* No, I won't update the manpage until this is "more done", lest someone
tries using vht and gets upset with me.
* No, I won't commit the regulatory database I'm testing with, so you'll
just end up with no VHT channels ever populated. Which is good, as there
isn't an 11ac driver in-tree yet to try it with.

configure the ic_curchan.
For fullmac devices it isn't /as/ important, as each virtual device
exposed by the firmware will likely have its own configuration and the
firmware figures out what to do to enable it.

sys/_sigset.h does not define osigset_t, but sys/sysproto.h sees

Do not hardcode elf64-tradbigmips as output format in BERI linker scrips.
Unfortunately, in-tree toolchain and external newer versions of binutils
mean two different things under that. When creating elf binaries using
external toolchain, gcc uses elf64-tradbigmips-freebsd and so linker
script file has to match in order for ld to be able to create the final loader
binary.
Rather than trying to guess, remove hardcoded output format directive from
the linker directive files and use CC to invoke the linker instead.
