--
At key generation of longer key size, OpenPGP card sends back "time
extension" with BWI=100, which is unusual value in the protocol and it
actually requires host having longer timeout like 43 seconds.

ccid_compare_BAI, otherwise scdaemon crashes.

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
device insertion/removal-s per second.
