  pkcs11: leverage sc_wait_for_event to avoid unneccesary queries to card

card_detect_all() is now used as global entry point even to reader
specific card detection (card_detect() is removed). This enforces
a constant update of reader_states so that no events are silently
dropped. This removes the need for having a timer in C_GetSlotInfo() for
avoiding too many queries. If the reader implementation (i.e.
reader-*.c) does not implement wait_for_event, then all slots will be
queried on request just like it used to be.

  PC/SC: fixed missing events of sc_wait_for_event()

pcsc_wait_for_event now exports an opaque structure which not only holds
the reader states but also indicates the SCARDCONTEXT, which is used to
query for events. This context is exclusively for these event requests,
which fixes the problem of events being swallowed by the primary
SCARDCONTEXT that is used for standard card/reader interaction. It seems
to be consistent across macOS, Windows and Linux that
SCardGetStatusChange returns new events based on those that have been
detected with the same context rather than those events that are based
on the input of LPSCARD_READERSTATE.

  PKCS#11: support C_WaitForSlotEvent for macOS and Windows

All platforms are supporting good enough `SCardGetStatusChange()` so
that `C_WaitForSlotEvent()` can be done on all platforms. On Linux, this
raises the minimum requirement for PCSC lite to 1.8.22 (17 June 2017)
