 - build: configure script now supports --with-drivers option instead of --disable-pcsclite and --disable-libusb (see --help)
 - nfc-mfultralight: we now can write OTP bytes if user want to

Changes:
 - API: nfc_initiator_select_tag() is now nfc_initiator_select_passive_target()
 - API: nfc_initiator_deselect_tag() is now nfc_initiator_deselect_target()
 - API: new function nfc_initiator_list_passive_targets() to list available targets in field

 - API: new types: nfc_target_type_t and nfc_target_t
 - API: new configuration option NDO_AUTO_ISO14443_4 to enable/disable auto iso14443-4 mode.

 - API: (experimental) new nfc_initiator_poll_targets() which allow to use hardware polling function
 - examples: add draft of a new example: nfc-sam. It tests the comunication with a connected SAM (Secure Access Module)
 - examples: add new example to show how to use new polling function

 - nfc-mfclassic: take care of 16-blocks-long sectors of Mifare Classic 4K in the nfc-mfclassic example's blocks counting routine.
 - nfc-mfclassic: now fails ealier when something goes wrong (this allow to prevent from false-success).
 - nfc-mfclassic: disable ISO14443-4 auto-switching in order to read devices that emulate Mifare Classic with ISO14443-4 compliance.(e.g. Nokia 6212 Classic)

Note: This release will not install extra headers (like mifare.h), programs that depends on should copy theses files into their sources.
