raisin: disable stubdoms and etherboot in xen

Raisin is about cloning (or downloading) components explicitly and
independently, rather than having the Xen build system clone and build
stuff as part of the build process.

Unfortunately it is not possible to build stubdoms outside the Xen tree
today, so just disable stubdoms for the moment.

Similarly etherboot support requires downloading ipxe, so remove it for
now.

With this patch, building Xen via Raisin doesn't fetch anything from the
web, aside from what is configure in the config file.

First, create a new global variable, PKGTYPE.  At the moment support "deb" and "rpm".

Define _check-package-$PKGTYPE which returns true if the package is
installed, false otherwise, and _install-package-$PKGTYPE which will
install a list of packages.

Define check-package(), which will take a list of packages, and check
to see if they're installed.  Any missing packages will be added to an
array called "missing".

Change _${COMPONENT}_install_dependencies to
${COMPONENT}_check_package.  Have these call check-package.

Define check-builddeps().  Define an empty "missing" array.  Call
check-package for "raisin" dependincies (like git and rpmbuild).  Then
call for_each_component check_package.

At this point we have an array with all missing packages.  If it's
empty, be happy.  If it's non-empty, and deps=true, try to install the
packages; otherwise print the missing packages and exit.

Add install-builddeps(), which is basically check-builddeps() with
YES=y.

Call check-builddeps from build() to close the loop.

Add function keyword to all other exported functions in commands.sh.

Remove --no-deps command line option.
