7aeac9ef18 ifnet: Replace if_addr_lock rwlock with epoch + mutex 
Run on LLNW canaries and tested by pho@

gallatin:
Using a 14-core, 28-HTT single socket E5-2697 v3 with a 40GbE MLX5
based ConnectX 4-LX NIC, I see an almost 12% improvement in received
packet rate, and a larger improvement in bytes delivered all the way
to userspace.

When the host receiving 64 streams of netperf -H $DUT -t UDP_STREAM -- -m 1,
I see, using nstat -I mce0 1 before the patch:

37d68cafec [net80211] convert all of the WME use over to a temporary copy of WME info. 
This removes the direct WME info access in the ieee80211com struct and instead
provides a method of fetching the data.  Right now it's a no-op but eventually
it'll turn into a per-VAP method for drivers that support it (eg iwn, iwm,
upcoming ath10k work) as things like p2p support require this kind of behaviour.

Tested:

* ath(4), STA and AP mode

TODO:

* yes, this is slightly stack size-y, but it is an important first step
  to get drivers migrated over to a sensible WME API.  A lot of per-phy things
  need to be converted to per-VAP before P2P, 11ac firmware, etc stuff shows up.

139b7f149e rtwn(4): change type for Tx power values (RTL8192C / RTL8188EU). 
Tx power values can easily fit into uint8_t + only 8 bits are written

malformed data (but limit is checked anyway).

Tested with RTL8188CUS, dev.rtwn.1.debug=0x2000 (no changes).

48003447fd rtwn_usb: add support for fragmented Rx. 
Since device can pass multiple frames in a single payload temporary
Rx buffer was big enough to hold all of them; now the driver can
concatenate a single frame from multiple payloads.

The Rx buffer size may be configured via tunable (dev.rtwn.%d.rx_buf_size).

Tested with:
 - rtl8188cus, rtl8188eu and rtl8821au (STA mode).
 - (by kevlo) rtl8192cu and rtl8188eu.
