rtwn: expand the ridx numbers to include VHT; add accessor macros

* expand the ridx field all the way through 4x4 11n (MCS0..MCS31)
* and then expand it through VHT 4x4 (MCS0..9 for each stream)
* add accessor macros to check if the rate is HT, VHT
* use accessor macros to check if the rate is HT rather than
comparing it against OFDM54 or RIDX_HT_MCS(0); the values
aobve HT MCS will be VHT, and we don't want to trigger on those!
* add a couple of appropriate TODO VHT bits in the TX path

Locally tested:

* RTL8192CU, STA mode
* RTL8188EU, STA mode
* RTL8821AU, STA mode
* RTL8192EU, STA mode

net80211/drivers: improve ieee80211_rx_stats for band

While IEEE80211_R_BAND was defined, there was no place to store the
band. Add a field for that, adjust ieee80211_lookup_channel_rxstatus()
to require it, and update drivers passing "R_{FREQ|IEEE}" in already to
provide the band as well. For the moment keep the fall-back code
requiring all three fields.

rtwn(4), urtwn(4): merge common code, add support for 11ac devices.

All devices:
- add support for rate adaptation via ieee80211_amrr(9);
- use short preamble for transmitted frames when needed;
- multi-bss support:
* for RTL8821AU: 2 VAPs at the same time;
* other: 1 any VAP + 1 sta VAP.
RTL8188CE:
- fix IQ calibration bug (reason of significant speed degradation);
- add h/w crypto acceleration support.
USB:
- A-MPDU Tx support;
- short GI support;
Other:
- add support for RTL8812AU / RTL8821AU chipsets
(a/b/g/n only; no ac yet);
- split merged code into subparts:
* bus glue (usb/*, pci/*, rtl*/usb/*, rtl*/pci/*)
* common (if_rtwn*)
* chip-specific (rtl*/*)
- various other bugfixes.

Due to code reorganization, module names / requirements were changed too:
urtwn urtwnfw -> rtwn rtwn_usb rtwnfw
rtwn rtwnfw -> rtwn rtwn_pci rtwnfw

Tested with RTL8188CE, RTL8188CUS, RTL8188EU and RTL8821AU.
