conftest: Make outgoing sequence number set by reset_seq configurable

This is useful for certain test cases. Passing the sequence number to
the callback requires a new struct that contains both the number and the
xfrm_usersa_id. The new configuration parameter is called oseq in
accordance with the kernel name, see the comment in the reset_cb
callback function for details.
conftest: Fix log level settings for stdout

This patch fixes bug #272 ("conftest ignores log settings for stdout").
http://wiki.strongswan.org/issues/272

According to the documentation of add_logger in src/libcharon/bus/bus.h,
the relevant log levels of a logger are registered with the logging
subsystem when adding the logger. If the log levels change later, the
logger must be re-added to propagate the new settings. In conftest.c,
the stdout logger is initialized and added before reading the logging
settings, but wasn't re-added after reading the settings.
conftest: Add support for time_format and ike_name options in log sections

Both options are well supported for normal operation but were completely
ignored by conftest, which used hard coded defaults. File options are
still missing but could be added in a similar way.
