The debug ring buffers is a purely debug mechanism to let the driver
report debug info like connection events, power events, etc to the
framework.
The framework used to previously dump out the raw byte stream in
the bugreport and the vendors had some tools to parse out the data.
This is now being changed to provide the framework with the
internal ring buffer structs to ease parsing this data in framework
itself. This will eventually be used in the new wifilogd daemon.

Some of these structs are used in the debug framework and hence needs to
live in types.hal. Add a |Sta| prefix to differentiate them from other
types similar to what is done for Nan and Rtt types.

Changes in the CL:
a) Unions are not allowed in the HIDL generated code that is going to be
used in java.
b) Few RTT constants were defined twice in the legacy rtt.h. One set
as enums, the other set as #define's. Remove the duplicated values in
the HIDL interface.

Interface is mostly a replication of the wifi_nan.h HAL header file.
1. All the methods are in |IWifiNanIface|.
2. Moved all the callbacks to |IWifiNanIfaceEventCallback.hal|.

3. Changed all the variable size arrays to vecs.

Having all the HIDL methods asynchronous, makes it hard for the
calling code to keep track of the operation status/result.
There are some operations which will generate asynchronous results (like
bgscan), convert all the other methods to synchronous methods.
The |EventCallback| objects will now just broadcast important events
(needed for other clients to listen for state changes). This will no
longer be used to send responses to every command sent to the HAL.

Add separate types of Iface/Network object for STA (station mode) and
P2P mode ifaces and associated networks. These expose very different
functionality and exposing 2 different types of objects makes the
interface cleaner.
Although, they're still represented via the same struct for both types
in the wpa_supplicant core.

Add the iface creation/retrieval/list method implementations in WifiChip.
WifiChip does not yet support the chip mode configuration. So, all
|createIface| method calls succeed today. Once the mode configuration
changes are in place, we will deny iface creation requests depending on
the iface combination supported in the current mode.
The iface objects are all invalidated and deleted on mode switches and
when HAL is stopped.

All the legacy HAL API's in the function table uses the "wlan0"
interface handle for the various operations. But, this is an internal
detail that should be abstracted inside WifiLegacyHal class. So, rename

Also, add methods to fetch the iface names to use for the various types
of HAL.

Create a RTT controller object to use for initiating all the RTT related
HAL opertations.
Since we don't want to fix the iface on which to initiate RTT operations,
these methods will be rooted in a new standalone object |RttController|.
Framework can decide to intiate an instance of |RttController| on a
specified iface or let the implementation pick one.

Create a child object under IWifiChip to represent each interface
within the chip. Each iface object has a |type| & |ifname| which should
help us uniquely identify them. This should help us expose methods that
are applicable only to a specific interface type.
While there,
Assign a unique id to every chip on the device.
Add IWifi.listChipIds() to retrieve the list of chip Id's avaiable on the
device. IWifi.getChip() will now use the provided Id to retrieve the
corresponding IWifiChip object(because HIDL language doesn't support
vec<HIDL objects>).

Convert the existing AIDL binder interface of wpa_supplicant to HIDL.
Summary of changes:
1. Every HIDL method returns an instance of |SupplicantStatus|
along with any others params (for getters). This is needed to return the
equivalent of |Binder::Status| to indicate errors in the args passed,
stale proxy, etc.
2. All constants are changed to enums. There were some constants which
should have been enums in the first place, but wasn't because AIDL did
not support enums. But, there are others which should be standalone
constants, but are enums now because constants are not supported in HIDL.
3. Conform to HIDL style guide.
