This patch simplifies the host-side work in the new /usr zfs filesystem
build process.

Previously, we copied the files to a temporary directory, used "cpio"
to archive them and sent its output to the guest with "netcat".

With this patch, we no longer have a temporary directory, and do not
need either cpio or netcat on the build machine.

Rather, mkzfs.py itself, using python (instead of a separate "nc" process),
connects to the guest and sends it the files - still using the CPIO format.

Rather than arbitrarily sleep for 3 seconds before the host tries to
connect to the guest (which might not be enough for some, or a waste
of time for others), with this patch the host looks at the guest's output
and connects when it sees the message "Waiting for connection".

Currently, OSv release numbers would look like this:

  $ git describe --tags --long
  v0.02-0-gc40b86b

Stop using "--long" and let "git describe" do the right thing:

  $ git describe --tags
  v0.01-298-g42d11fb
  $ git tag v0.02
  $ git describe --tags
  v0.02

We are switching to Amazon S3 for OSv pre-built image releases.

The script uses S3cmd:

  http://s3tools.org/s3cmd



which can be installed on Fedora with:

  yum install s3cmd python-magic

Please remember to configure your Amazon S3 credentials before running
the script:

  s3cmd --configure

To release a new version of OSv:

  git tag <version>

  ./scrips/release-s3

  git push --tags

This patch adds version numbering to the loader. We use "git tag" for
generating an unique version number with a little bit of shell script
magic to make sure version number is always up-to-date.

When the build/ directory is on tmpfs then 'cache=none' option makes
qemu fail with error:

    could not open disk image build/release/usr.img : Invalid argument

Using tmpfs for build/ makes a _huge_ difference in build time on some
setups.

This patch adds fallback to 'unsafe' mode when direct IO is not
supported.

This patch adds a "osv runqueue" command to gdb, which shows the (sorted)
run queue of each CPU. Note that the run queue does not include the thread
currently running - just those which are ready to run.

This command is useful for debugging the scheduler and load balancer, but
is less generally useful than the "osv info threads" command, which lists
all threads, specially marking those which are runnable as well as those
which are running.
