for signicantly optimized UDP socket I/O when using a single UDP
socket from many threads or processes that share it, by avoiding
significant locking and other overhead in the general sosend()
path that isn't necessary for simple datagram sockets. Specifically,
this change results in a significant performance improvement for
threaded name service in BIND9 under load.

Add back in a scheme to emulate old type major/minor numbers via hooks into
stat, linprocfs to return major/minors that Linux app's expect. Currently
only /dev/null is always registered. Drivers can register via the Linux
type shim similar to the ioctl shim but by using
linux_device_register_handler/linux_device_unregister_handler functions.
The structure is:
struct linux_device_handler {
char *bsd_driver_name;
char *linux_driver_name;
char *bsd_device_name;
char *linux_device_name;
int linux_major;
int linux_minor;
int linux_char_device;
};
Linprocfs uses this to display the major number of the driver. The
soon to be available linsysfs will use it to fill in the driver name.
Linux_stat uses it to translate the major/minor into Linux type values.
Note major numbers are dynamically assigned via passing in a -1 for
the major number so we don't need to keep track of them.
This is somewhat needed due to us switching to our devfs. MegaCli
will not run until I add in the linsysfs and mfi Linux compat changes.

destination. These checks are needed so we do not install
a route looking like this:
(0) 192.0.2.200 UH tun0 =>
When removing this route the kernel will start to walk
the address space which looks like a hang on 64bit platforms
because it'll take ages while on 32bit you should see a panic
when kernel debugging options are turned on.
The problem is in rtrequest1:
if (netmask) {
rt_maskedcopy(dst, ndst, netmask);
} else
bcopy(dst, ndst, dst->sa_len);
In both cases the len might be 0 if the application forgot to
set it. If so ndst will be all-zero leading to above
mentioned strange routes.
This is an application error but we must not fail/hang/panic
because of this.

- Fix bfe_encap so that it will pass the address of the mbuf back up to its
caller if/when it modifies it, as it does when doing a m_defrag on a mbuf chain.
- Make sure to unload the dmamap for ALL fragments of a packet, not just the first
- Use BUS_DMA_NOWAIT for all bus_dmamap_load calls so that the allocation of the
map is not delayed - this driver is not set up to handle such delays.
- Reduce the number of RX and TX buffers bfe uses so that it does not use more
bounce buffers than busdma is willing to allow it to use
With these changes, the driver now works properly for a user with a 2GB system,
and it also works on my system when the acceptable address range is lowered to 128MB.
Previously, both of these setups would act up after a few minutes of activity.

interact very nicely with HTTP proxies: Since proxies do not know
that all the files on portsnap1.freebsd.org are identical to the
files with the same names on portsnap2.freebsd.org, said proxies end
up downloading and storing files in duplicate.
This commit uses the HTTP_PROXY environment variable, if set, to
generate a random number seed for use in selecting a mirror. This
means that if several systems all have the same HTTP_PROXY value set,
they will ask the proxy to fetch files from the same mirror (unless
that mirror fails, in which case all the systems will use the same
second choice, et cetera).
Portsnap still doesn't interact very well with "transparent" HTTP
proxies, but there's nothing I can do about those.

track of which mirrors we have tried and try a different mirror if we
fail when trying to download the SSL public key or the snapshot
signature.
Failures later in the download process will not result in switching to
a different mirror, for two reasons:
1. If is very unlikely that a mirror will fail partway through the
process of downloading updates.
2. If we switched from a more recently updated mirror to a less
recently updated mirror partway through the download process, we would
end up failing anyway because we would be trying to fetch files which
the second mirror didn't have yet.

I tested this with 2 amr controllers in one box. It seems to work
okay with them.
