After the gpg-card tool has issued a Yubikey specific command the
current application is not anymore correctly selected. This then
results in all kind of errors. We detect this now and try to
re-select the last app.

the challenge response interaction.

This allows us to return only KEYPAIRINFO lines for keys we can
actually use.
* scd/app.c (app_dump_state): Also print the refcount.
(maybe_switch_app): Make sure the app exists on the card.
--
When switching the current card and the card does not support the same
apps as the former, we now reset the app to the first one.
Testcase is to use a standard OpenPGP card and a P15 card.

This is required because we change what we emit as serialno of OpenPGP
cards but existing keys still use the old form of the serial
number (i.e. with a firmware version).

--
This patch gets us back to a unique serial number for cards and
provides a stable serial number as printed for Yubikeys.
Because we use a slightly different serial number now for Yubikeys and
cards only supporting OpenPGP card we need to come up with another
change so that the version number of OpenPGP serial numbers are
ignored when comparing card serial numbers. This is so that existing
stub keys of gpg-agent will continue to work.

We need to use es_fopen on Windows to cope with non-ascii file names.
This is quite a large but fortunately straightforward change. At a
very few places we keep using stdio (for example due to the use of
popen).

* scd/app.c (select_all_additional_applications_internal): Re-select
first app. Add arg 'ctrl'.
--
Usually keygrip based access to the Yubikey does a switching back and
forth and thus keeps the card and scdaemon's internal state in sync.
However, if we do only a listing scdaemon did not reselect the first
application (e.g. OpenPGP) after adding other applications (e.g. PIV)
and thus led to wrong info returned in a listing.

This has been tested with a D-Trust card featuring 3072 bit keys.
Note that non-repudiation key for a qualified signature does not yet
