This avoids Coverity being unhappy that only lower bound was defined, well I hope
lower_bounds: Checking lower bounds of signed scalar "waiting_time" by "waiting_time > 0".
CID 1090343 (#1 of 1): Untrusted value as argument (TAINTED_SCALAR)
tainted_data: Passing tainted variable "waiting_time" to a tainted sink.
sleep(waiting_time);
nfc_exit(context); was called 2 times
CID 1090348 (#1 of 1): Use after free (USE_AFTER_FREE)53. deref_arg:
Calling "nfc_exit(nfc_context *)" dereferences freed pointer "context".
(The dereference is assumed on the basis of the 'nonnull' parameter
attribute.)
- Fixed the suppression of the auto-fixup for linking against MS built libs
- Fixed all the formatting warnings by shifting to inttypes.h specifiers
- shifted to %lu for DWORD printf
This becomes more consistent with all other pass by pointer of most structures.
Additionally, this should lessen stack memory usage, as building strings with str_nfc_target would push the target (283 bytes) plus then a copy of the info objects (up to 275) onto the stack as it dives into the sprintf functions.
Lastly, this makes my attempt at a .NET wrapper easier, as I can make passing by pointer work, but passing by value seems to bomb on the interop right now.

- nfc_device is now an opaque type;
- PN53x specific errors are not public anymore;
- nfc_device_name() renamed to nfc_device_get_name() for the sake of consistency;
- examples/*, utils/* uses the new nfc_device_get_name() function instead of access directly to struct's content;
- new error defined: NFC_ERFTRANS for notifying about RF transmission error, its used by mifare.c to detect permissions error on mifare;
- drivers initiator_transceive_bytes() function now returns libnfc's error code on failure (<0), and received bytes count on success (>=0);
- remove some unused errors.
