test helpers: move test-* to t/helper/ subdirectory
This keeps top dir a bit less crowded. And because these programs are for testing purposes, it makes sense that they stay somewhere in t/ Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

+/*
+ * This program can either change modification time of the given
+ * file(s) or just print it. The program does not change atime or
+ * ctime (their values are explicitly preserved).
+ *
+ * The mtime can be changed to an absolute value:
+ *
+ * test-chmtime =<seconds> file...
+ *
+ * Relative to the current time as returned by time(3):
+ *
+ * test-chmtime =+<seconds> (or =-<seconds>) file...
+ *
+ * Or relative to the current mtime of the file:
+ *
+ * test-chmtime <seconds> file...
+ * test-chmtime +<seconds> (or -<seconds>) file...
+ *
+ * Examples:
+ *
+ * To just print the mtime use --verbose and set the file mtime offset to 0:
+ *
+ * test-chmtime -v +0 file
+ *
+ * To set the mtime to current time:
+ *
+ * test-chmtime =+0 file
