For filesystems which use vfs_mount_error() to log an error, this
char buffer will be populated with a string error message.
If nmount() fails, in addition to printing out strerror(errno),
print out the "errmsg" populated by vfs_mount_error().
(somewhat) meaningful message and terminate the build. It'd be
nice to print a proper URL from which to fetch the file but that
seems problematic. Leave a suggested starting point in this file
(TBD: add it to the man page).

described in kern/104678 and may be useful in other situations too.

Rather than rendering a different version of the release notes for
every architecture, we now produce a single release notes document
that covers all architectures.
This change makes document maintenence easier (because there is no
longer a need to support each architecture specifically in the
src/release/doc/ and www/ build infrastructures). It's also
easier to read because there is now exactly one release notes document,
and readers can see changes that affected various subsets of
architectures.

rather than treating them as a fatal exception and halting. At least one
storage BIOS (some newer mpt(4) parts) have a breakpoint instruction in
their disk read routine.

Make part of John Birrell's KSE patch permanent..
Specifically, remove:
Any reference of the ksegrp structure. This feature was
never fully utilised and made things overly complicated.
All code in the scheduler that tried to make threaded programs
fair to unthreaded programs. Libpthread processes will already
do this to some extent and libthr processes already disable it.
Also:
Since this makes such a big change to the scheduler(s), take the opportunity
to rename some structures and elements that had to be moved anyhow.
This makes the code a lot more readable.
The ULE scheduler compiles again but I have no idea if it works.
The 4bsd scheduler still reqires a little cleaning and some functions that now do
ALMOST nothing will go away, but I thought I'd do that as a separate commit.
Tested by David Xu, and Dan Eischen using libthr and libpthread.
driving xl_watchdog() in order to avoid races accessing if_timer.
While at it relax the watchdog a bit by reloading it in xl_txeof()/
xl_txeof_90xB() if there are still packets enqueued.
- Use bus_get_dma_tag() so xl(4) works on platforms requiring it.
- Don't bother to set if_mtu to ETHERMTU, ether_ifattach() does that.
hme_watchdog() in order to avoid races accessing if_timer.
- Use bus_get_dma_tag() so hme(4) works on platforms requiring it.

This operation is a part of a reorganization of the release notes,
which will (when completed) provide one version of the release notes
covering all architectures, rather than multiple versions (each
describing one architecture).
