perf debug: Remove needless include directives from debug.h All we need there is a forward declaration for 'union perf_event', so remove it from there and add missing header directives in places using things from this indirect include.

perf tests: Add breakpoint modify tests Adding to tests that aims on kernel breakpoint modification bugs. First test creates HW breakpoint, tries to change it and checks it was properly changed. It aims on kernel issue that prevents HW breakpoint to be changed via ptrace interface. The first test forks, the child sets itself as ptrace tracee and waits in signal for parent to trace it, then it calls bp_1 and quits. The parent does following steps: - creates a new breakpoint (id 0) for bp_2 function - changes that breakpoint to bp_1 function - waits for the breakpoint to hit and checks it has proper rip of bp_1 function This test aims on an issue in kernel preventing to change disabled breakpoints Second test mimics the first one except for few steps in the parent: - creates a new breakpoint (id 0) for bp_1 function - changes that breakpoint to bogus (-1) address - waits for the breakpoint to hit and checks it has proper rip of bp_1 function This test aims on an issue in kernel disabling enabled breakpoint after unsuccesful change.
