Introduce support for `repo.fetchcmd` configuration, allowing users to specify a custom command to fetch project data instead of `_RemoteFetch`. When `repo.fetchcmd` is specified, `repo` will execute it instead of `_RemoteFetch` during the network half of sync. Note that `repo.fetchcmd` requires `repo.uselocalgitdirs` to be enabled. The command is executed in a subshell with project-context environment variables, including the new `REPO_TREV` (target revision resolved to a commit hash) and `REPO_PROJECT_FETCH_URL`. After execution, `repo` verifies that the target commit is available and that the tracking ref and FETCH_HEAD are correctly updated. Tested with: ``` > ~/git-repo/repo init -u https://android-review.googlesource.com/platform/manifest \ --repo-url file:///usr/local/google/home/gavinmak/git-repo \ --groups developers \ --no-repo-verify \ --use-local-gitdirs ... > git config --file .repo/manifests.git/config repo.fetchcmd 'mkdir -p $REPO_PATH && cd $REPO_PATH && if [ ! -d .git ]; then git init && git remote add aosp $REPO_PROJECT_FETCH_URL; fi && git fetch aosp $REPO_TREV && git reset --hard $REPO_TREV && mkdir -p .git/refs/remotes/aosp && echo $REPO_TREV > .git/refs/remotes/aosp/main && echo $REPO_TREV > .git/FETCH_HEAD' > ~/git-repo/repo sync -j32 warning: repo is not tracking a remote branch, so it will not receive updates; run `repo init --repo-rev=stable` to fix.
