reed 42346787b7 Change or add history. I checked the 1bsd archives and this first 
appeared in 1BSD (before it was known as 1BSD). I looked at code and
later sccs history to confirm.  In the case of rewritten code, we are
not consistent in manpages indicating that history.

dholland d4bd1c2d11 Tidy up: we no longer need FIRSTVALID for its original purpose, so change 
the name of the symbol to something that applies to the remaining use.

dholland 6eb9e0a428 When the wtmp file is empty, for the "wtmp[x] begins..." output, use 
the last mod time of the wtmp file (in practice, the time it was last
rotated, which is when it begins) instead of the current time, which
wasn't ever particularly useful. PR 39444.

dholland ce683a0035 Keep track of the timestamp of the last (thus oldest) record seen and use 
it to print "wtmp[x] begins" at the end, instead of knowing where to look
in the final utmp buffer to get a final timestamp out. This is both tidier
and fixes a problem with wtmpx files, which is that if the header record
is missing (which it seems to be on my machines) it would fetch the wrong
time out, and if you happened to have a one-record wtmp file it would use
the current time instead. This change restores the traditional behavior
of printing the time of the oldest record in the file, and if no records
are present to use the current time.

It might be a bug that wtmpx files don't seem to have the header
record they supposedly ought to.

cbiere a8d0a33445 - Applied patch by David Holland from PR bin/35354. 
- Use EXIT_SUCCESS/EXIT_FAILURE instead of 0/1.
 - Additional check for regular file.
 - Use pread() instead of lseek() + read().
 - Check for partial read to prevent out-of-bounds memory access.
 - Added FIXME to onintr(): This is no proper signal handler albeit might
   not really matter here.
