e17fa5c75d scd: Remove --debug-disable-ticker option.
* scd/scdaemon.c (ticker_disabled): Remove.
(handle_tick, need_tick): Remove.
(handle_connections): Don't check ticker_disabled.

--

Now, removal of device/card is only done by the function
scd_update_reader_status_file, it should be called if needed.

Use pipe to wake up select(2).  If UNIX-only, signal could be used.  For
portability, "self-pipe" is better, here.  Setup for non-blocking for
pipe fds are not needed, because speed of USB device insertion is
limited by human physical interaction;  No one can do hundreds of

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.

--

This is long standing bug.  So far, Le was not exact value.
Since forthcoming change will introduce exact value of expected length
of response data, this change is needed.

68b59bbc42 Spelling: correct spelling of "passphrase".
There were several different variant spellings of "passphrase".  This
should fix them all for all English text.

I did notice that po/it.po contains multiple instances of
"passhprase", which also looks suspect to me, but i do not know
Italian, so i did not try to correct it.

In OpenPGP card specification 3.0, ECC is introduced.  So far, do_genkey
only supported RSA.  Since KDF spec. is needed to calculate the
fingerprint, it is hard coded in app-openpgp.c.  But it's defined by
OpenPGP ECC (RFC-6637), and card does nothing with KDF in fact.
