Some chips are capable of detecting when a tag is out of the field, so
they could send a netlink event about it to userspace.

Export new attributes sensb_res for tech B and sensf_res
for tech F in the target info (returned as a response to
NFC_CMD_GET_TARGET).
The max size of the attributes nfcid1, sensb_res and sensf_res
is exported to user space though include/linux/nfc.

This patch is an initial implementation for the NFC Logical Link Control
protocol. It's also known as NFC peer to peer mode.
This is a basic implementation as it lacks SDP (services Discovery
Protocol), frames aggregation support, and frame rejecion parsing.
Follow up patches will implement those missing features.
This code has been tested against a Nexus S phone implementing LLCP 1.0.

We can have the NFC core layer allocating the tx head and tail
room for the drivers and avoid 1 or more SKBs copy on write on
the Tx path.
