Hello,

This patch add a new option "--cob" to gdbserver. When gdbserver called with this option, it will open support of continue over breakpoints.
Then we can use testsuite test the function of continue over breakpoints.

To support this function, I add new function step_over_breakpoints to let the thread that is stop by breakpoints before continue all theads.  It is not very fast.  But I think for test is OK.  Please give me more comments about it.

Thanks,
Hui
