Add support for confirmation APIs.
This code implements new keystore APIs for confirmations.
Also add new 'confirmation' verb to the keystore_cli_v2 command to be
used for testing confirmations. It will block until there's a
callback. Example invocations:
phone:/ # keystore_cli_v2 confirmation --prompt_text="Hello World" --extra_data=010203 --ui_options=1,2,3
Waiting for prompt to complete - use Ctrl+C to abort...
Confirmation prompt completed
responseCode = 0
dataThatWasConfirmed[30] = {0xa2, 0x66, 0x70, 0x72, 0x6f, 0x6d, 0x70, 0x74, 0x6b, 0x48, 0x65, 0x6c, 0x6c, 0x6f, 0x20, 0x57, 0x6f, 0x72, 0x6c, 0x64, 0x65, 0x65, 0x78, 0x74, 0x72, 0x61, 0x43, 0x01, 0x02, 0x03}
phone:/ #
If a prompt is already being shown, the |OperationPending| return code
(code 3) is returned:
phone:/ # keystore_cli_v2 confirmation --prompt_text="Hello World" --extra_data=010203 --ui_options=1,2,3
Presenting confirmation prompt failed with return code 3.
Canceling a prompt:
phone:/# keystore_cli_v2 confirmation --prompt_text="Hello World" --extra_data=010203 --cancel_after=1.5
Sleeping 1.5 seconds before canceling prompt...
Waiting for prompt to complete - use Ctrl+C to abort...
Confirmation prompt completed
responseCode = 2
dataThatWasConfirmed[0] = {}
