[v3 for 4.5 2/2] make: Make "src-tarball" target actually make a source tarball

[George Dunlap]

At the moment, making a release tarball is an annoyingly manual
process that involves running "git archive" into a temporary directory.

Script this process up and make a target, so that the release manager
can simply type "make src-tarball-release" and have everything show up
nice and neat in dist/xen-$version.tar.gz.  "make src-tarball" will
make a version number based on git describe, which will typically have
the most recent tag, number of commits since that tag, and the git
commit id of the current HEAD.

Signed-off-by: George Dunlap <george.dunlap@eu.citrix.com>

---

v2:
* Put quotes around assignments with variables in them
* Avoid pushd/popd
* Get rid of unnecessary error checks (since set -e will take care of it)
* Make a function to do the git archive
* Add "src-tarball-release" to do a clean version (e.g., 4.4.1)
* "src-tarball" will name it based on "git describe" (includes a short commit hash).
* Add mkdir -p $xen_root/dist/ to the script so that it works on a freshly cloned tree

v3:
* Use fixed filename for temporary directory
* Make script "crash-only"
* Include all subtrees, configured or not

Is HEAD really the right thing here?

My git-speak isn't good enough to be sure about suggesting an
alternative, but it would seem to me that the respective
*_REVISION variables from ./Config.mk should be used here.
Iiuc HEAD may refer to a newer commit.

HEAD should be the current state of the tree, and that's what we want:
just as the build will take the current state of the git subtrees, we
want the mktarball script by default to take the current state of
whatever the git subtrees are.

But the "make src-tarball[-release]" at the moment will first call
subtree-force-update on all the trees, so by the time we run the
script HEAD will be pointing to the _REVISION variables from
Config.mk.  I was going to add an option to allow the trees to be left
as they are, but that turns out to be more complicated than it's worth
right now, I think.

Ah, okay. As said, my git-speak is pretty limited, so never mind
the comment then.

IanJ,

Just a refresh: It would be nice if this could make it into 4.5, so a
review in the next week or so might be helpful.
