rtwn: add VHT awareness to rtwn_chan2centieee()

Since we're not doing 80+80 yet, this is easy - just use
the freq1 centre.

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.

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.
