[PING/rfa/testsuite/threads] schedlock.c: add copyright notice

[Michael Chastain <mec.gnu@mindspring.com>]

Previously sent 2004-07-31 and 2004-08-08 ... ping!

This patch adds a copyright notice to schedlock.c.  It doesn't touch
anything else in schedlock.c, but naturally I'm doing this because I
want to patch schedlock.c next (so that it compiles with gcc HEAD).

Daniel Jacobowitz created schedlock.c in 2002, and the file was edited
in 2003 but not in 2004.  Following a previous discussion with Andrew
Cagney and Dan Berlin, I'm not including 2004 in the list of copyright
years.

Date sources: ChangeLog and the cvs log.

Testing: I ran schedlock.exp 32 times before and after on native
i686-pc-linux-gnu to make sure no absolute line numbers got hosed.

Okay to commit?
