pack-objects: warn on split packs disabling bitmaps
It can be tempting for a server admin to want a stable set of
long-lived packs for dumb clients; but also want to enable bitmaps
to serve smart clients more quickly.
Unfortunately, such a configuration is impossible; so at least warn
users of this incompatibility since commit 21134714 (pack-objects:
turn off bitmaps when we split packs, 2014-10-16).
Tested the warning by inspecting the output of:
make -C t t5310-pack-bitmaps.sh GIT_TEST_OPTS=-v
