- improve performances between pcscd and libpcsclite
  see http://archives.neohapsis.com/archives/dev/muscle/2005-q4/0086.html

- allow the use of extended APDU without breaking libpcsclite ABI
  For now we have either normal APDU (max 256 bytes) or extended APDU
  (--enable-extendedapdu, max 32K bytes) but not both

- include Apple patches and improvements (if possible/needed)

- power on the card _only_ if an application requests a connection
  see Alioth bug #301965

- use a callback from IFD handler to pcscd instead of pooling to get the
  card status: better performance, possible lower power consumption
