"mac80211: Fix WMM driver queue configuration"
inadvertedly broke iwlwifi, because now mac80211
configures the QoS settings before assoc, and
therefore before HT. Thus, iwlwifi no longer told
the device about the HT setting, which it needs
to -- and thus throughput went down a lot. Fix
this by resending the QoS command to the device
not only when QoS/WMM settings change, but also
when HT changes.

When building 4965 without 5000+ there were a
lot of build errors due to functions being used
that weren't even compiled in. To fix this move
some code around and only compile the HCMD code
for 5000+ series as it's not used for 4965.

My previous patch to clean up all RXON handling
inadvertently broke IBSS because it failed to
take into account that unlike in AP mode, IBSS
requires beacons to be sent only after setting
the RXON assoc.

Fix this, clean up the code a bit, improve the
error checking around this, and also react to
beacon changes in IBSS mode from mac80211.

In order to simplify the flow, and make new
enhancements easier, separate out the RXON
processing for modern AGN (5000 and newer)
from RXON processing for the older 3945 and
4965 devices. Avoid changing these old ones
to avoid regressions and move their code to
a new file (iwl-legacy.c). 4965 gets the
commit_rxon that used to be common for all
AGN devices, but with removed PAN support.

The new RXON processing is more central and
does more work in committing, so that it is
easier to follow.

To make it more evident what is split out
for legacy, split the necessary operations
for that into a new struct iwl_legacy_ops.
Those parts that still exist in the new AGN
code don't need to be parametrized.
