Subject: [PATCH v2 0/5] Stack independent BT HAL test tool

v2:
- license changed to apache
- source folder changed to hal-client (underscore to dash)
v1:
This tool is for testing Android HAL interfaces from command line.
Due to lack of readline on Android simple equivalent is hand coded.
This tool can be used with bluedroid stack so no glib dependency.

Tool source code is in folder hal_client, please comment if it should be
somewhere else.

Comments welcome.

Best regards
Jerzy Kasenberg

Could we get structure initializations like this to use follow the
coding style, i.e.:

static bt_callbacks_t bt_callbacks = {
.member1 = sizeof(),
.member2 = adapter_state_changed_cb,
...
};

This way you can directly see that the right members are initialized to
the right values and there's no risk that e.g. two members with the same
type are swapped (something the compiler wouldn't warn about).

As a general point to others working on the android code: if there are
any other similar places elsewhere in the code please fix those too.

The user space coding style convention is to have a space between the
type cast and the variable. In this case you might make the code more
readable by adding an extra variable, something like:

bluetooth_device_t *btdev;

...

btdev = (bluetooth_device_t *) device;
if_bluetooth = btdev->get_bluetooth_interface();
...

This is first code that actually calls HAL functions.
Functions defined in bt_interface_t can be executed.

Subject: [PATCH v2 4/5] android: Add text conversion helpers to haltest

Application uses a lot of text in the form of defines found in header
files to represent arguments and output.
Conversion helpers keep functionality of converting string as
bt_status_t or uuid in one place.
