networking.7 : create network quickstart guide

have a network quickstart guide in-band, in base, in the system manual.

x86/xen: fix accounted interrupt time
The current addition to the interrupt nesting level in
xen_arch_intr_handle_upcall() needs to be compensated in

there's been an interrupt nesting.
Such extra interrupt nesting count lead to statclock() reporting idle time as
interrupt, as the call from interrupt context will always be seen as a nested
one (td->td_intr_nesting_level >= 2) due to the nesting count increase done by
both xen_arch_intr_handle_upcall() and intr_execute_handlers().
Fix this by adjusting the nested interrupt count before dispatching interrupts

release: Build dvd image before staging pkgs

release: Use the ABI of the target release to fetch packages
- Point --rootdir at the installed destdir in the dvd tree. This
causes pkg to determine the ABI from the installed destdir instead
of the host's binaries. Previously the result was that packages
for the host's ABI were always downloaded breaking cross-releases
(e.g. arm64 releases built on an amd64 host included amd64
packages on the DVD ISO image rather than arm64 packages). This
also handles version mismatches, and I tested this by cross-building
a 15.x arm64 release on a 14.x amd64 host.
- As a result, pkg now does a chdir(3) to the rootdir before running,
so the -o argument to fetch needs to be updated to be relative to
rootdir instead of the CWD as make runs.
- Add a new ROOTDIR variable to limit references to "dvd" to one
place. Ideally ROOTDIR would be an argument to this script so
that it didn't really know about the dvd layout at all.
- While here, simplify creation of symlinks by just using a longer
path to the link name instead of using 'cd' in the shell before
invoking ln(1). Also use ln -sf to create the pkg.pkg symlink
rather than rm + ln.
People get confused when some software (VirtualBox, etc) does not work as
expected (or at all) after a major upgrade.
We have a nice way to deal with this when using sources, namely including
PORTS_MODULES in /etc/make.conf, but we lack something similar for binary
updates.

advises the user to recompile from ports to avoid problems.
