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.
