Spec: Add rootdir (as in chroot).

parseSpec(): Pass rootdir argument.
rpm.c: Rework bigMode enum to simplify per-mode option checks.
build/build.c: Attempt a chroot before execl().
falloc.c: thinko: test for non-existent packages database was broke.
makeTempFile(): Skip possible URL leader on tempfile name expansion.
rpmio.c: Mkdir/Chdir/Rmdir/Rename/Chroot/Unlink syscall wrappers.
rpmdb.c: Coalesce and simplify legacy openDatabase() wrappers.
uninstall.c: Skip possible URL leader on chroot arg.
