This change allows following invocation of app_select_openpgp, which
may work well (if the problem is device side for initial connection).

With trylock_slot, it may return SW_HOST_BUSY.  This may occur when

Simply using lock_slot is much easier for user of apdu_send_direct.

--

The previous fix 192113552f did not
help, thus the new hypothesis is that PC/SC might return a valid
context with the value -1.  We now use a dedicated flag to track the
validity of the context.

The reference counting seems to be superfluous and is a relict due to
backporting from 2.3.  Removed.

--

Note that depending on the card backend (ccid or PC/SC) it might be
necessary to first send a reset followed by SERIALNO to get an updated
list of reader.  Or well send KILLSCD.

The pretty printing of Assuan data lines does only work if you connect
direct to scdaemon because the wrapper in gpg-agent does not know
about this and combines the Assuan lines again.
