Fix to 'gdb detach' stub
With this patch, 'gdb detach' correctly resumes the inferior execution after detaching the debugger. The bug was caused by qemu asking gdb to execute a syscall (isatty) after the detach, and then waiting (forever) for the reply. I fixed this by properly setting gdb_syscall_mode appropriately in the 'detach' packet handling, so subsequent syscalls are solved by qemu rather than gdb.
