Use LWP IDs with ptrace register requests on FreeBSD.
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.
