>Description:
Similar to the previous PR, but for gdb.threads.

This is a separate PR because gdb.mi and gdb.threads have different maintainers.
>How-To-Repeat:
Run the test suite with gcc HEAD.
>Fix:
(1) Add copyright notices to gdb.thread/*.c.
(2) Add "#include" lines to gdb.thread/*.c.

The fix is in progress.
