[PATCH 7/9] builtin: Support RUN_SETUP_GENTLY to set up repository early if found

From: Nguyễn Thái Ngọc Duy <pclouds@gmail.com>

Attempts to access gitdir are everywhere, even before cmd_*() is called (examples: alias handling, pager configuration, work tree). Because the repository has not been found, repository-specific information (i.e., $GIT_DIR/config) can not be read. This leads to obscure bugs.

So the sooner we setup gitdir, the less trouble we may have to deal with.

This patch sets up the infrastructure. Later patches will teach particular commands to use it where applicable.
