- Use time_t instead of abstract minutes to store validity time to make sure we support all possible values.
- Return UNIX time from it to support both relative and absolute expire times.
- Pass a current time to gsm340_validity_period() to compute the absolute expire time if a relative time is specified. What time is "current" is to be decided by callers.
- We also introduce SMS_DEFAULT_VALIDITY_PERIOD macros to reduce number of magic values.
The number of digits is the number of used octets times two (two
digits per octet). The result has been successfully dissected by
wireshark. It has not been tested with real phones.

openbsc.git, after the sms code had been migrated here:
introduce HAVE_TM_GMTOFF_IN_TM
Not all architectures have the tm.tm_gmtoff member. This fixes cygwin builds.
