    Fix potential infinite loop in build-iso

    Function generate_dep_list is creating a DEPLISTFILE
    with a lot of unwanted 'installing package xxx' messages
    when it should only contain a list of unresolved
    dependencies.

    On the next iteration we waste a lot of time trying to install
    nonexistant packages 'installing' and 'packages', and re-installing
    packages we already have.

    Instead of converging on an empty DEPLISTFILE, we converge
    on a DEPLISTFILE that just reiterates the same list of
    'installing package' if we are lucky, which we usually are,
    but not always.

    Add subdir PKG_GITREVCOUNT support

    This update introduces the PKG_GITREVCOUNT variable for package-based
    auto-versioning. Similar to GITREVCOUNT, PKG_GITREVCOUNT will
    calculate the number of commits in the corresponding package's
    directory. This allows each package within a git repo to be
    independently auto-versioned.

    Use of the PKG_BASE_SRCREV variable is optional. If it is not defined,
    the PKG_GITREVCOUNT will count all commits in the package directory.
    If it is defined, it will count a range of commits, with
    PKG_BASE_SRCREV as the starting point.

    To use this, include the following in the package's build_srpm.data
    file:
    TIS_PATCH_VER=PKG_GITREVCOUNT

    This can also be combined with GITREVCOUNT, if a package has local
    files in addition to an external repo to be factored in. This would
    add the count from PKG_GITREVCOUNT to GITREVCOUNT in calculating the
    TIS_PATCH_VER value:
    TIS_PATCH_VER=GITREVCOUNT+PKG_GITREVCOUNT
