This allows gdb to fetch per-thread registers for multi-threaded FreeBSD processes. Export get_ptrace_pid() from inf-ptrace.c and use it to determine the PID to pass to ptrace in pan-BSD native targets. NetBSD and OpenBSD also accept LWP IDs for ptrace requests to fetch per-thread state. gdb/ChangeLog: * amd64bsd-nat.c (amd64bsd_fetch_inferior_registers): Use get_ptrace_pid. (amd64bsd_store_inferior_registers): Use get_ptrace_pid. (amd64bsd_dr_get): Use get_ptrace_pid. (amd64bsd_dr_set): Use get_ptrace_pid. * i386bsd-nat.c (i386bsd_fetch_inferior_registers): Use get_ptrace_pid. (i386bsd_store_inferior_registers): Use get_ptrace_pid. (i386bsd_dr_get): Use get_ptrace_pid. (i386bsd_dr_set): Use get_ptrace_pid. * inf-ptrace.c (get_ptrace_pid): Export. * inf-ptrace.h (get_ptrace_pid): Declare. * ppcfbsd-nat.c (ppcfbsd_fetch_inferior_registers): Use lwp id. (ppcfbsd_store_inferior_registers): Use lwp id.
