In order to provide more flexibility for the test writers,
add per-test-method cleanups in addition to the per-class cleanups.
Now the test 'test_one' can perform cleanup by either defining
per-class 'cleanup' method (typically used in VNET classes) and
per-test method 'cleanup_test_one'. The latter has preference.
In order to handle paramatrization, testid is passed as a single
argument to both of the methods.

Should we add more consumers or small (or large) objects would become a

Implement cfg80211_{get,put}_bss currently doing malloc/free bits,
so hopefully the drivers get the calls right.
cfg80211_get_bss() sets up a lookup structure which may also take a
result (first hit wins) and calls ieee80211_scan_iterate() comparing
the various values in the iterator funcion. Some of the checks are
partially pointless (as it seems the drivers are not interested in
these parts [ANY] but we keep them for documentation purposes should
futher values arise in the future).
We currently only iterate over the first VAP which will do for now.

Prior to Conrad's changes to replace session integer IDs with a
pointer to the driver-specific state in commit 1b0909d51a, the
driver had to find the softc pointer from the adapter before it could
locate the ccr_session structure for a completed request. Since
Conrad's changes, the ccr_session pointer can now be obtained directly
from the crp. Add a backpoint from ccr_session back to ccr_softc and
use this in place of the ccr_softc member in cxgbe's struct adapter.

getattr is very expensive and in important cases only gets called to get

that statistic.
As a step towards that goal make size-only consumers use a dedicated

of the buffer returned by fgetln isn't really safe, so switch to using
getline() instead.
Note that these fixes are a subset of those applied to a
