Add the option to ask for VHT operation similarly to the way ht40 is
configured - either by adding 'vht' param to the relevant p2p_*
commands or by configuring p2p_go_vht=1 in the configuration file.
This patch only adds the configuration option (e.g., via control
interface). The actual handling of the VHT parameter (asking the driver
to use VHT, etc.) will be done by the following patch.

beacon_int (in TU) can now be used to configure Beacon interval for AP
mode operations (including P2P GO) in wpa_supplicant. This can be set
either in a network block or as a global parameter in the configuration
file (or with "SET beacon_int <value>" control interface command) to
apply for all networks that do not include the beacon_int parameter to
override the default.
In addition, this commits extends the dtim_period parameter to be
available as a global parameter to set the default value. dtim_period is
now stored in the configuration file, too, if it was set.

This new mechanism can be used to make wpa_supplicant using external
storage (e.g., key store in the operating system) for passwords,
passphrases, and PSKs. This commit is only adding the framework part
needed to support this, i.e., no actual configuration parameter can
yet use this new mechanism. In addition, only a simple test backend
is added to allow developer testing of the functionality.

MCS Rates can be disabled to force to slower speeds when using HT.
Rates cannot be forced higher.
HT can be disabled, forcing an 802.11a/b/g/n station to act like

A-MPDU Factor and A-MPDU Density can be modified.
Please note that these are suggestions to the kernel. Only mac80211

This can be used to limit which frequencies are considered when
selecting a BSS. This is somewhat similar to scan_freq, but will
also affect any scan results regardless of which program triggered
the scan.
This makes it clearer which files are including header from src/common.
Some of these cases should probably be cleaned up in the future not to
do that.
In addition, src/common/nl80211_copy.h and wireless_copy.h were moved
into src/drivers since they are only used by driver wrappers and do not
need to live in src/common.
This allows background scanning and roaming decisions to be contained in
a single place based on a defined set of notification events which will
hopefully make it easier to experiment with roaming improvements. In
addition, this allows multiple intra-ESS roaming policies to be used
(each network configuration block can configure its own bgscan module).
The beacon loss and signal strength notifications are implemented for
the bgscan API, but the actual events are not yet available from the
driver.
The included sample bgscan module ("simple") is an example of what can
be done with the new bgscan mechanism. It requests periodic background
scans when the device remains associated with an ESS and has couple of
notes on what a more advanced bgscan module could do to optimize
background scanning and roaming. The periodic scans will cause the scan
result handler to pick a better AP if one becomes available. This bgscan
module can be taken into use by adding bgscan="simple" (or
bgscan="simple:<bgscan interval in seconds>") into the network
configuration block.
A new network block parameter, scan_freq, can be used to specify subset
of frequencies to scan. This can speed up scanning process considerably
if it is known that only a small subset of channels is actually used in
the network. A union of configured frequencies for all enabled network
blocks is used in scan requests.
Currently, only driver_nl80211.c has support for this functionality.
For example, following parameter marks 2.4 GHz channels 1, 6, 11 to be
scanned: scan_freq=2412 2437 2462
Move the shared IEEE 802.11w enum definition into src/common/defs.h to
avoid redefinition when both configuration structures are included into
the same file.
This version is adding the configuration option (mode=2) for this and
driver capability reporting to figure out whether AP mode can be used.
However, this does not actually implement any real functionality yet.
Added a new configuration option, wpa_ptk_rekey, that can be used to
enforce frequent PTK rekeying, e.g., to mitigate some attacks against TKIP
deficiencies. This can be set either by the Authenticator (to initiate
periodic 4-way handshake to rekey PTK) or by the Supplicant (to request
Authenticator to rekey PTK).
With both wpa_ptk_rekey and wpa_group_rekey (in hostapd) set to 600, TKIP
keys will not be used for more than 10 minutes which may make some attacks
against TKIP more difficult to implement.
