6812782462 hlr_auc_gw: Allow Milenage RES length to be reduced
Some USIM use shorter RES length than the 64-bit default from Milenage.
Such cases did not interoperate with the hlr_auc_gw implementation. Make
it possible to configure the RES length 4..8 octets, i.e., 32 to 64
bits) to support such USIM.

154a1d5f7f hostapd: Fix some compilation errors
If NEED_AP_MLME=y is not defined, compilation might
fail under some configurations:

src/ap/drv_callbacks.c:594:2: warning: implicit declaration of
function ‘hostapd_acs_completed’ [-Wimplicit-function-declaration]

src/ap/sta_info.c:253: undefined reference to `sae_clear_retransmit_timer'

Fix these errors by adding the missing hostapd_acs_completed() stub,
and defining NEED_AP_MLME in case of CONFIG_SAE.

68fa00c341 ACS: Allow specific channels to be preferred
The new acs_chan_bias configuration parameter is a space-separated list
of <channel>:<bias> pairs. It can be used to increase (or decrease) the
likelihood of a specific channel to be selected by the ACS algorithm.
The total interference factor for each channel gets multiplied by the
specified bias value before finding the channel with the lowest value.
In other words, values between 0.0 and 1.0 can be used to make a channel
more likely to be picked while values larger than 1.0 make the specified
channel less likely to be picked. This can be used, e.g., to prefer the
commonly used 2.4 GHz band channels 1, 6, and 11 (which is the default
behavior on 2.4 GHz band if no acs_chan_bias parameter is specified).

the assignments made in the Makefile. The CFLAGS values in the Makefile
are ignored, if defined directly in the make command line.

a156ffda61 Add support for testing memory allocation failures
The new control interface command TEST_ALLOC_FAIL and GET_ALLOC_FAIL can
now be used to trigger memory allocation failures for testing purposes.
TEST_ALLOC_FAIL sets a failure conditions with
<count>:func[;func][;func]... string and GET_ALLOC_FAIL returns the
current state using the same format. Whenever an allocation is made with
a matching backtrace of calling functions, the count is decremented by
one and once zero is reached, the allocation is forced to fail.

Function names can be prefixed with either '=' or '?' to get different
matching behavior. '=' requires this specific function to be the next
one in the backtrace (i.e., do not skip any other functions in the list
which is the default behavior). '?' allows the function to be optionally
present in the backtrace.
