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.

Add a debug-statement from NetBSD, and then rework all debug-statements

2004-03-08T19:20:06Z

so the program compiles without errors or warnings when DEBUG is defined on sparc64 with 64-bit time_t's. Also have debug statements include the year when printing records from a different year than 'now'. Also print out a special timestamp in debug statements when ut_time==0.

Minor style(9) fixes. remove a register keyword, correct two indents.

Noticed while comparing to OpenBSD version.

Convert K&R-style routine definitions to C89 style, partially to reduce

diffs with OpenBSD. This causes no changes to the object produced.

Remove unused #includes. Eliminate castings by using size_t instead of int.
