NFCEE. The corresponding conn_info is now created in

The current implementation limits nci_core_conn_create_req()
to only manage NCI_DESTINATION_NFCEE.
Add new parameters to nci_core_conn_create() to support all
destination types described in the NCI specification.
Because there are some parameters with variable size dynamic
buffer allocation is needed.

The NFCC sends an NCI_OP_RF_NFCEE_ACTION_NTF notification
to the host (DH) to let it know that for example an RF

NFC_EVT_TRANSACTION is sent through netlink in order for a
specific application running on a secure element to notify
userspace of an event. Typically the secure element application
counterpart on the host could interpret that event and act
upon it.
Forwarded information contains:
- SE host generating the event
- Application IDentifier doing the operation
- Applications parameters

According to the NCI specification, one can use HCI over NCI
to talk with specific NFCEE. The HCI network is viewed as one
logical NFCEE.
This is needed to support secure element running HCI only
firmwares embedded on an NCI capable chipset, like e.g. the
st21nfcb.
There is some duplication between this piece of code and the
HCI core code, but the latter would need to be abstracted even
more to be able to use NCI as a logical transport for HCP packets.

In order to communicate with an NFCEE, we need to open a logical
connection to it, by sending the NCI_OP_CORE_CONN_CREATE_CMD
command to the NFCC. It's left up to the drivers to decide when
to close an already opened logical connection.

NFCEEs (NFC Execution Environment) have to be explicitly
discovered by sending the NCI_OP_NFCEE_DISCOVER_CMD
command. The NFCC will respond to this command by telling
us how many NFCEEs are connected to it. Then the NFCC sends
a notification command for each and every NFCEE connected.
Here we implement support for sending
NCI_OP_NFCEE_DISCOVER_CMD command, receiving the response
and the potential notifications.

The current NCI core only support the RF static connection.
For other NFC features such as Secure Element communication, we
may need to create logical connections to the NFCEE (Execution

In order to track each logical connection ID dynamically, we add a
linked list of connection info pointers to the nci_dev structure.

As there can be several pipes connected to the same gate, we need
to know which pipe ID to use when sending an HCI response. A gate
ID is not enough.
Instead of changing the nfc_hci_send_response() API to something
not aligned with the rest of the HCI API, we call nfc_hci_hcp_message_tx
directly.

Several pipes may point to the same CLF gate, so getting the gate ID
as an input is not enough.
For example dual secure element may have 2 pipes (1 for uicc and
1 for eSE) pointing to the connectivity gate.
As resolving gate and host IDs can be done from a pipe, we now pass
the pipe ID to the event received handler.

Changes:
* Extract the Listen mode activation parameters from RF_INTF_ACTIVATED_NTF.
* Store the General Bytes of ATR_REQ.
* Signal that Target mode is activated in case of an activation in NFC-DEP.
* Update the NCI state accordingly.
* Use the various constants defined in nfc.h.
* Fix the ATR_REQ and ATR_RES maximum size. As per NCI 1.0 and NCI 1.1, the
Activation Parameters for both Poll and Listen mode contain all the bytes of
ATR_REQ/ATR_RES starting and including Byte 3 as defined in [DIGITAL].
In [DIGITAL], the maximum size of ATR_REQ/ATR_RES is 64 bytes and they are
