This is it. I promise.
ACTION_TECHNOLOGY_DISCOVERED -> ACTION_TECH_DISCOVERED
This was missed in our technology->tech rename.
Hide TagTechnology.reconnect()
This is used to reset any per-connection state in a tag, by reconnecting
to it. The first problem is that it belongs on Tag, not TagTechnology. The
second problem is that it may become redundant once we add Tag.rediscover()
which will also reconnect to the tag, and will also return a new Tag with
newly created technologies enumerated. And the third and most significant
problem is that you can already achieve the same result by just calling
close() followed by connect().
Hide Tag.createMockTag()
This API cannot be used reliably. First it requires using int[] for the
technology list, but those int constants are now hidden. Second it requires
knowledge of the extras parcel used to fill technology specific data - also
not public.
Introduce TagTechnology.isConnected()
Every child class already impelmented this, and given that connect() and
close() are defined on the interface, then isConnected() should be there
too.
Modify Ndef.getType to return a string (not int)
Allows more flexibility in adding new NDEF types. Current public strings are
org.nfcforum.ndef.type1
org.nfcforum.ndef.type2
org.nfcforum.ndef.type3
org.nfcforum.ndef.type4
com.nxp.ndef.mifareclassic
Add NdefFormatable.formatReadOnly()
This allows you to make the tag read-only at the same time as performing
format and write. It is important because we currently don't have any
public API to re-enumerate a tag technology list after making a tag
NDEF compatible, so you can't perform the format as a seperate step
without physically removing the tag from field and returning it.
Modify Readonly -> ReadOnly
Make Tag class final

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 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.
