Add test-chmtime: a utility to change mtime on files
This is intended to be a portable replacement for our usage of date(1), touch(1), and Perl one-liners in tests. Usage: test-chtime (+|=|-|=+|=-)<seconds> <file>..." '+' increments the mtime on the files by <seconds> '-' decrements the mtime on the files by <seconds> '=' sets the mtime on the file to exactly <seconds> '=+' and '=-' sets the mtime on the file to <seconds> after or before the current time.
