9a493fab73 WNM: Add candidate list to BSS transition query
Add an option to configure a candidate list to BSS transition query
("list" as the second argument to WNM_BSS_QUERY). The candidate list is
built from the available scan results. If no updated scan results (< 10
sec) are available, the command fails.

75d65857d5 WNM: Use recent scan results on BSS transition request
If the last scans are recent (for now, less than ten seconds old), use
them instead of triggering a new scan when a BSS Transition Management
Request frame is received. As a fallback, allow a new scan to be
triggered if no matches were found.

e1117c1c01 WNM: Optimize BSS transition management scans
When the list of preferred transition candidates is received, use the
identified channels to optimize the following scan so that no time is
wasted on other channels.

093226783d WNM: Simplify how candidate subelements are stored
There is no need to use a separately allocated data structures for this.
A bitfield indicating which information is present and variables within
struct neighbor_report are simpler to use and more efficient.

897a5ccee8 WNM: Remove unnecessary present flag
The structures are all allocated, so the pointer can be compared to NULL
to determine whether the subelement was present.

dbfb8e82ff Remove unnecessary EVENT_RX_ACTION
This driver event was used separately for some Action frames, but all
the driver wrappers converted to this from information that would have
been enough to indicate an EVENT_RX_MGMT event. In addition, the
received event was then converted back to a full IEEE 802.11 management
frame for processing in most cases. This is unnecessary complexity, so
get rid of the extra path and use EVENT_RX_MGMT for Action frames as
well as other management frame subtypes.
