This was done in a mostly automated fashion. I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.
The first step was a sed-based addition of the parent type to the subclass
registration functions.
The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.
Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,
and type_register_static calls.
We are almost fully converted to QOM after this commit.

ATR size exceeding the limit is diagnosed, but then we merrily use it
anyway, overrunning card->atr[].
The message is read from a character device. Obvious security
implications unless the other end of the character device is trusted.
Spotted by Coverity. CVE-2011-4111.

arpa/inet.h is not available for w32, so commit
edbb21363fbfe40e050f583df921484cbc31c79d breaks
w32 compilations.
This is fixed by using qemu_socket.h.

The passthru ccid card is a device sitting on the usb-ccid bus and
using a chardevice to communicate with a remote device using the
VSCard protocol defined in libcacard/vscard_common.h
Usage docs available in following patch in docs/ccid.txt

see lengthy comment below.
Changes from v15->v16:
Behavioral changes:
* return correct size
* return error instead of assert if client sent too large ATR
* don't assert if client sent too large a size, but add asserts for indices to buffer
* reset vscard_in indices on chardev disconnect
* handle init from client
* error if no chardev supplied
* use ntoh, hton
* eradicate reader_id_t
* remove Reconnect usage (removed from VSCARD protocol)
* send VSC_SUCCESS on card insert/remove and reader add/remove
Style fixes:
* width of line fix
* update copyright
* remove old TODO's
* update file header comment
* use macros for debug levels
* c++ style comment replacement

ccid-card-passthru: force chardev user wakeup by sending Init
The problem: how to wakeup the user of the smartcard when the smartcard
device is initialized?
Long term solution: have a callback interface. This was done via
the deprecated so called chardev ioctl interface.
Short term solution: do a write. Specifically we write an Init message.
And we change the client to send it's own Init message regardless of
receiving this one. Additional Init messages will be regarded as
acceptable, the first one received after connection establishment is
the determining one wrt capabilities.
