Garance A Drosehn e3b218cd7b Add a check for wtmp records which have invalid values for ut_time. Wtmp
records with time==0 get "the time of the last valid record", while records
where time goes backwards (compared to the previous record) are skipped.
Also prints a message saying how many records were changed or skipped due
to these checks. Check was inspired by a simpler check in OpenBSD's version.

This is all meant to sidestep problems that Tillman Hodgson noticed with 'ac'
when running sparc64 with 64-bit time_t's.  The real problem is whatever is
creating wtmp records with ut_time==0, of course, but I have not yet figured
out what is doing that.
