60970a328e did one half of the job
of making rssi relative to nf and numbers for radiotap were fine.
net80211 internally works with .5 dBm units thus we need to apply a
* 2 to the value we pass in to c_rssi; leave a comment explaining.
Note: it is only ifconfig in user space which re-adjust it for printing
or contrib/wpa for calculations. Other applications getting values
from kernel also have to apply the maths.

dev_alloc_skb() comapred to alloc_skb() reserves some headroom
at the beginning of the skb which is used by drivers.
Split the code for the two cases and reserve NET_SKB_PAD space,

LinuxKPI is asking for single-segment mappings. Some (wireless) drivers
are using this to map multi-pages and our busdma framework is not very
friendly to that as single-segments [D31823]. Add a counter so we can
track when this happens to gather more information.

As in 4a22cd6c4e nf and rss should be
signed and not unsigned. Change the types in the header and while
here change a magic number to a define as done elsewhere (value does
not change).
When calculating c_rssi we need to make it relative so subtract nf.
And while here improve the debug output.
This will hopefully fix ifconfig wlanN list scan S:N output which
tools use to chose a BSSID and help net80211 internal calculations.

Historically 32-bit Linuxulator under amd64 emulated the real i386
behavior. Since 3d8dd983 the old i386 Linux world can't be used under
amd64 Linuxulator as it don't know anything about amd64 machine (which
is returned now by newuname() syscall). So, add a knob to allow to swith
the behavior and use i386 Linux binaries on amd64.
Set knob to the new behavior as I think this is common to the modern
Linux distros.

Compiling another driver on i386 revealed two problems:
- ieee80211_tx_info.status.status_driver_data space needs to be
calculated. While a pointer is 32bit vm_paddr_t is 64 bit on i386
so we didn't fit more than one of these in but needed more space.
- the arguments to ieee80211_txq_get_depth() are expected to
unsigned long and not uint64_t.
No user noticable changes.

32-bit architectures other than i386 have 64-bit time_t which results
in a struct timespec with 12 bytes for tv_sec and tv_nsec, and 4 bytes
of padding. Zero the padding holes in struct stat32 and struct
freebsd11_stat32.
i386 has 32-bit time_t; struct timespec is 8 bytes and has no padding.
Found by inspection, prompted by a report by Reno Robert of Trend Micro
Zero Day Initiative. The originally reported issue (ZDI-CAN-14538) is
already fixed in all supported FreeBSD versions (it was addressed
incidentally as part of the 64-bit inode project).

generic. Hide all debugging behind #ifdef for now and turn off.
Rename the debugging sysctl so we can start adding more to the
