the connection.

It found that libusb_get_pollfds is not supported on Windows.
Besides, it's a bit difficult to use for the select loop.
Thus, we use the thread named ccid_usb_thread, instead.

With Gnuk Token, it works fine as expected. With Gemalto reader,
intr_cb is not called when card is removed. So, the macro
LIBUSB_WORKS_EXPECTED_FOR_INTERRUPT_ENDP is not defined yet.

This is a long standing bug. There are two different things; The
serialization of allocating a new SLOT, and the serialization of using
the SLOT. The latter was implemented in new_reader_slot by lock_slot.
However, the former was not done. Thus, there was a possible race where
a same SLOT is allocated to multiple threads.

APP is the abstraction of the card application. For management of
cards, it is better to focus on the APP instead of the physical reader.
This change makes support of multiple card/token easier.

* common/util.h: Provide replacement for GPGRT_ATTR_ macros when using
libgpg-error < 1.20.
* common/mischelp.h: Ditto.
* common/types.h: Ditto.

Given that libgpg-error is a dependency of all GnuPG related libraries
it is better to define such macros at only one place instead of having
similar macros at a lot of places. For now we need repalcement
macros, though.
The vreader table makes the code more clear by explicitly talking
about APDU slots and reader indices. It also accommodates for future
extensions.
* scd/scdaemon.h (server_control_s): Remove READER_SLOT.
* scd/scdaemon.c (scd_init_default_ctrl): Do not init READER_SLOT.

(server_local_s): Add field VREADER_IDX as replacement for
the READER_SLOT in server_control_s. Change all users.
(slot_table): Rename to vreader_table. Change all users.
(vreader_slot): New.
(do_reset, cmd_apdu): Map vreader to apdu slot.

(open_card): Map vreader toapdu slot. Pass slot to
check_application_conflict.
(scd_command_handler): Init VREADER_IDX.
(update_reader_status_file): Reset SLOT field on error.
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
