IOException on close() can be useful to indicate that in-progress transactions
were canceled.
I also audited all of our tech classes to make sure every function that needs
to throw IOException does so.

o Some javadoc updates
o writeBlock -> writePages (Block means something else in NFC Forum).
o validate page offset

This makes the system more flexible and allows
adding new technology types without having to
update the API.

Also make sure they are non-negative.
This is not documented in Mifare Classic spec, but based on findings from NXP:
- Operand should be stored in little-endian format in the transceive buffer
- Tag ignores the sign bit on the operand, its effectively 31-bit unsigned
- Overflow and underflow generates an error.

When generating a mock tag (after a NDEF exchange over LLCP), one of
the internal fields is set to null. This was causing NullPointerException
when being converted to a Parcel.
This is fixed by not including this field in the Parcel for mock tags.

Remove method overloading for combinations of sector+block addressing.
Instead provide methods that more closly match the raw commands, and more
efficient helpers to convert between blocks and sectors.
o fix off-by-one bug in getBlockCountInSector()
o add BLOCK_SIZE
o remove DESFIRE not operating in classic emulation (SAK 0x20)
o hide isEmulated(), there is no use case, and the info is available elsewhere
o getTotalBlockCount() -> getBlockCount()
o getBlockCount(int) -> getBlockCountInSector(int)
o introduce blockToSector() and sectorToBlock()
o remove authenticateBlock()
make it really clear that authentication is per sector, and reduce function
explosion. blockToSector() allows you to use authenticateSector...
o explicit authenticateSectorWithKeyA() / authenticateSectorWithKeyB()
get rid of magic boolean
o remove all (int sector, int block) parameters
always address by absolute block. this makes the API crystal clear, and
helps reduce function explosion
o validation of all sector and block indices
o dont & 0xff when converting to byte - its redundant
o Remove TYPE_OTHER. Mifare Classic types are well-known and stable.

The NPP is only usable by the foregorund
activity to prevent dispatching confusion
on the far end.

The method is needed since makeReadOnly() only works on T1T/T2T. Also removed
makeLowlevelReadonly(), since NFC forum does not allow setting the CC and the lock
bits separately.

attemptDeadServiceRecovery() is a hack to recover from NfcService dying. It
should be a rare event, and is only needed in NfcAdapter which is a long-lived
object.
TagTechnology objects are transient, it is acceptable for them to go stale
when NFC service dies. Lets not complicate the code with recovery for a rare
event.

BasicTagTechnology.transceive(byte[] raw) should work for most child classes,
except those that want to disable (raw) transceive.
Current plan is not to add transceiveMifare() etc - use explicit methods
instead.
Add package scoped BasicTagTechnology.transceive(byte[] rata, boolean raw)
as a helper to remove code duplication.

It's not easy to determine if this
is possible, so instead apps should
attempt a format and handle errors
in the format request.

- It's useful to have accessors at block level, so apps don't really have to know
about the sector structure (and how many blocks there are in a sector).
- There's no way to tell whether a read/write/ didn't work because of auth
failure. The documentation should be changed to make this point clear.
- Added increment/decrement commands, for atomic increment/decrement of value blocks.
Change-Id: I590feacbcd1443f1be7a86ab046a5b1f33e2e04c
- The NfcService now allows for connecting to a specific technology;
- The "active" parts of technology classes may not be used at the same time.
Change-Id: Ibb569f51cc6da4f3e24df9d0850c6f49a022b0c2
- Added getNdefCached() to return the message read at discovery time.
- Fixed format() to check ndef before doing the write:
libnfc actually requires a checkNdef to be done before writing.
