returned by the server matched what we requested, and blindly appended
what we received to what we already had. This could go two ways: if the
delivered offset was higher than expected, the local file would contain
duplicate data, while if it was lower than expected, there would be data
missing from the middle of the file. Furthermore, if the transfer was
interrupted again, each subsequent attempt would compound the error.
Fix the first problem by restarting the transfer from scratch if there
is a gap, and the second by explicitly seeking to the correct location
in the local file so as to overwrite any duplicated data.

on vfc_name to set vfc_typenum, so that vfc_typenum doesn't
change when file systems are loaded in different orders. This
keeps NFS file handles from changing, for file systems that
use vfc_typenum in their fsid. This change is controlled via
a loader.conf variable called vfs.typenumhash, since vfc_typenum
will change once when this is enabled. It defaults to 1 for
9.0, but will default to 0 when MFC'd to stable/8.

gpt and zfs boot blocks are not nearly as size-constrained as boot2
from which they inherited their current optimization and anti-optimization
options. As such the current options do not provide any benefit, but
make debugging of the code much harder.
Also, it has been demonstrated that combination of -mrtd and
-fno-unit-at-a-time may result in mis-compilation of the boot code
with the current base gcc.
Additionally, intermediate assembly file filtering is removed for
zfsboot.
The new boot blocks are all compile- and boot- tested using qemu.
gptzfsboot is tested with real hardware.

(r225485). When setting an interface name to it, the following
configurations will be enabled:
1. "no_radr" is set to all IPv6 interfaces automatically.
2. "-no_radr accept_rtadv" will be set only for $ipv6_cpe_wanif. This is
done just before evaluating $ifconfig_IF_ipv6 in the rc.d scripts (this
means you can manually supersede this configuration if necessary).
3. The node will add RA-sending routers to the default router list
even if net.inet6.ip6.forwarding=1.
This mode is added to conform to RFC 6204 (a router which connects
the end-user network to a service provider network). To enable
packet forwarding, you still need to set ipv6_gateway_enable=YES.
Note that accepting router entries into the default router list when
packet forwarding capability and a routing daemon are enabled can
result in messing up the routing table. To minimize such unexpected
behaviors, "no_radr" is set on all interfaces but $ipv6_cpe_wanif.

of the device boundry.
While this is generally ok, the problem is that all the consumers
handle similar cases (and expect to catch) ENOSPC for this (for a
reference look at minidumpsys() and dumpsys() constructions). That
ends up in consumers not recognizing the issue and amd64 failing to
retry if the number of pages grows up during minidump.
Fix this by returning ENOSPC in dump_write() and while here add some
more diagnostic on involved values.
