Debugger support. Unfinished. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22695 a95241bf-73f2-0310-859d-f6bbb57e9c96

/*
* Always include the public arch_debugger.h headers. The structures defined there are prefixed with the respective architecture name. Useful for remote debugging a different architecture. * <x86/arch_debugger.h>: Introduced a structure for the FPU state, so that it isn't left to the debugger. * Removed the _kern_get_thread_cpu_state() syscall. Was originally intended for bdb compatiblity, but isn't really needed. * Kernel x86 arch_get_debug_cpu_state(): The use of fnsave was broken, since it reinits the FPU after saving the state. This resulted in weird results when debugging functions using the FPU. We now use fxsave, if available. Otherwise fnsave + frstor should be used -- not fully implemented yet. Same for arch_set_debug_cpu_state(). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31682 a95241bf-73f2-0310-859d-f6bbb57e9c96
