commit b2f7c7e8b7046bf3dd99e3fb7329feb962a6bc7d

    Make linux_stop_lwp be a shared function
    
    Both GDB and gdbserver had linux_stop_lwp functions with identical
    declarations.  This commit moves these to nat/linux-nat.h to allow
    shared code to use the function.
    
    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.
