[PATCH 05/14] Make linux_stop_lwp be a shared function

[Gary Benson <gbenson at redhat dot com>]

Both GDB and gdbserver had identical linux_stop_lwp functions.
This commit moves its declaration to nat/linux-nat.h to allow
shared code to use it.

gdb/ChangeLog:

	* linux-nat.h (linux_stop_lwp): Move declaration to...
	* nat/linux-nat.h (linux_stop_lwp): New declaration.

gdb/gdbserver/ChangeLog:

	* linux-low.h (linux_stop_lwp): Remove declaration.
