(get_ccid_error_string): Add some error code mappings.
(send_apdu): Pass error codes along for drivers already supporting
them.
(host_sw_string): New.
(get_ccid_error_string): Use above.
(send_apdu_ccid): Reset the reader if it has not yet been done.
(open_ccid_reader): Don't care if the ATR can't be read.
(apdu_activate_card): New.
(apdu_strerror): New.
(dump_reader_status): Only enable it with opt.VERBOSE.

* apdu.c (open_ct_reader, open_pcsc_reader, open_ccid_reader)
(reset_ccid_reader, open_osc_reader): Call dump_reader_status only
in verbose mode.
* app-openpgp.c (do_getattr): Fix for sending CA-FPR.
* app-openpgp.c (app_openpgp_readkey): Fixed check for valid
exponent.
* app-openpgp.c (do_setattr): Sync FORCE_CHV1.
