Add samdb_result_account_expires() function.
Windows uses 2 different values to indicate an account doesn't expire: 0 and 9223372036854775807 (0x7FFFFFFFFFFFFFFFULL). This function looks up the value of the accountExpires attribute and if the value is either value indicating the account doesn't expire, 0x7FFFFFFFFFFFFFFFULL is returned. This simplifies the tests for account expiration. There is no need to check elsewhere in the code for both values, therefore a simple greater-than expression can be used. (This used to be commit 7ce5575a3a40cca4a45ec179a153f7e909065a87)
