agent: New option --s2k-count.
* agent/agent.h (opt): New field 's2k_count'. * agent/gpg-agent.c (oS2KCount): New enum value. (opts): New option --s2k-count. (parse_rereadable_options): Set opt.s2k_count.
This option is useful to speed up the starting of gpg-agent and in
cases where the auto-calibration runs into problems due to a broken
time measurement facility.
