Unlike other devices, sending packets on the loopback device causes the
netif_rx() function to be called from the net_bh worker thread. Since
the thread is already running, it can't wake itself up when calling
mark_bh(). Use a new variable to indicate when net_bh work is pending.
* glue-include/linux/interrupt.h (net_bh_raised): Declare new global
variable.
(mark_bh): Set net_bh_raised to 1 before waking up net_bh worker thread.
* loopback.c (loopback_xmit): Add comment giving details about locking.
* sched.c (net_bh_raised): Define new global variable.
(net_bh_worker): Wait for net_bh_raised to become true and reset it
before processing net_bh work.

This change fixes a problem that can occur with non-blocking (and also
blocking for very short times) select/poll calls. The problem occurs because
the timeout is implemented at the client side. For a non-blocking call, this
means that (depending on the code path taken in the C library) the client
could get a timeout without a full RPC round-trip to the server. Moving the
implementation of the timeout to the servers guarantees a full round-trip,
and correct results for non-blocking calls.
The modifications in this change depend on the availability of the recently
added pthread_hurd_cond_timedwait_np function in libpthread.

Complete overhaul of pfinet based on the IPv4 networking code from the
Linux 2.2.12 kernel sources. This page describes a single unified set
of interdependent changes, but there are so many changes that I have
broken up the log entry into paragraphs based on rough topical
divisions of the work involved.
Subset of verbatim Linux 2.2.12 sources imported on a vendor branch.
* linux-src: New directory, see README for details.
* README: New file, describes linux-src layout and procedures for
tracking Linux source updates.
Light modifications to linux-src files to avoid really bending over
backwards with the glue macros. All modifications to files in
linux-src are conditionalized by #ifdef _HURD_.

refcnt and identity; elide members fasync_list, file.

(rtnl_shlock, rtnl_shunlock) [! _HURD_]: Conditionalize contents on
this, making these no-ops #ifdef _HURD_.

and SIOCSIFNETMASK code from devinet_ioctl.
* glue-include/asm, glue-include/linux: New directories.

Remove assert, since we always get passed IGMP_ALL_HOSTS.
(ethernet_thread): Make static.
(ethernet_demuxer): Use __mutex_lock in place of mutex_lock, so as to
get cthreads instead of linux/spinlock.h glue macros. Lock
net_bh_lock instead of global_lock. Set SKB->protocol with
eth_type_trans before calling netif_rx.
(ethernet_initialize): New function, one-time initialization broken
out of ethernet_open.
(ethernet_open): Ports setup moved to ethernet_initialize.
Don't use `errno' to avoid glue conflicts.

ops->sendto, which no longer exist. If O_NONBLOCK is set, set
MSG_DONTWAIT in msg_flags.
(S_socket_recv): Always use ops->recvmsg instead of ops->recv, which
no longer exists. If O_NONBLOCK is set, set MSG_DONTWAIT in flags.

Some of the new files in glue-include came from the old glue headers
in the asm and linux directories, but most were substantially modified.
* devices.c: File removed. The equivalent glue is now elsewhere.
