This is needed because downstream packagers, e.g. Debian, Ubuntu, etc, also keep the source code in git, but do not want to enable the 'git_update' mode; with the current code, that's not possible even if the downstream package specifies --disable-git-update. The previous parameters are deprecated but still available; the --enable-git-update parameter maps to --with-git-submodules=3Dupdate and --disable-git-update parameter maps to --with-git-submodules=3Dvalidate. The configure script behavior is slightly modified, where previously the dtc, capstone, and slirp submodules were not validated when --disable-git-update was specified (but were updated with git-update enabled), now they are validated when using --with-git-submodules=3Dvalidate and are only ignored when using --with-git-submodules=3Dignore.
