iw: add TID specific configuration command

Use command NL80211_CMD_SET_TID_CONFIG to perform per-node TID specific
configuration. If peer is not specified, then configuration is applied
to all the peers. Currently kernel supports configuration of the
following parameters:
- short/long retry
- mpdu/msdu aggregation on/off
- rts/cts on/off
- noack on/off

Examples:
Apply configuration for specific peer and TIDs:
$ iw dev wlan0 set tidconf peer 1:2:3:4:5:6 tids 0x3 ampdu off tids 0x2 sretry 10 lretry 100
$ iw dev wlan0 set tidconf peer 1:2:3:4:5:6 tids 0x1 override ampdu off amsdu off

Apply configuration for all peers and all TIDs:
$ iw dev wlan0 set tidconf tids 0xff ampdu off amsdu off sretry 10 lretry 100 noack off

Apply configuration for all peers and specific TIDs:
$ iw dev wlan0 set tidconf peer 0xff:0xff:0xff:0xff:0xff:0xff tids 0x1 ampdu off amsdu off

iw: 'phy <name> reg get' shouldn't dump all domains

Right now, 'iw phy ... reg get' gets translated to NLM_F_DUMP, which
dumps all domains. But this command really is looking for non-DUMP
semantics -- it only wants the domain for the specified wiphy, or (per
the kernel's choice) the global, if the wiphy doesn't have its own.

We can achieve this by skipping the handle_reg_get() -> "reg dump"
indirection.

no longer need to spell out the list of files and can just

iw: change __cmd section scheme to fit gcc/clang

There are some behaviour differences in how gcc and clang
fill a special section like the one we use for __cmd here.

In both compilers, obviously all variables declared like
this end up in the special __cmd section.

However, alignment and padding is applied differently by
different compilers and linkers, and as such it is hard to
really rely on being able to treat this like an array.

To avoid all these issues, put just *pointers* to the
structures into the special section, which makes it easy
to skip NULL pointers (resulting from padding) and has no
issues with alignment as they're always smaller than the
alignment applied.

iw: Add support for controlling tx power for per station

This patch allows userspace to set transmit power,
in dBm units, to a station associated to the AP.

To set a limit tx power of 20 dBm:
iw wlan0 station set <mac-addr> txpwr limit 20

To revert the user defined tx power for a station:
iw wlan0 station set <mac-addr> txpwr auto

iw: add command to inject a frame via direct mesh link to mesh peer

Add mpath command to inject ethernet frame over direct mesh link to
given peer, bypassing the mpath table lookup. This helps to send data
frames over unexcersized direct mesh path, which is not selected as
next_hop node. This can be helpful in measuring link metrics.

Format:
$ iw dev <devname> mpath probe <Peer MAC> frame <pattern>

Example:
$ iw wlan0 mpath probe aa:bb:cc:dd:ee:ff frame aa:bb:cc:dd:ee:ff:kk:ll:mm:nn:oo:pp:yy:zz

Frame pattern is supplied as hex pattern of the form aa:bb:cc without
leading 0x. Frame type and length are expected to be of ethernet frame
type.
