[Re-done with git.]
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.
